CK60 steel is one of the higher carbon content (0.60%) steels. It is more difficult to fabricate than the lower carbon grades.


Designation by Standards:

  • Mat No1.1221
  • DIN Ck65
  • EN -
  • AISI 1060

Soft Annealing:
  • Heat to 650-700°C, cool slowly in furnace. This will produce a maximum Brinell hardness of 241.
  • Hardening: Harden from a temperature of 800-830°C, 810-840°C followed by water or oil quenching. Normalizing
  • Normalizing temperature (°C): 820-850°C.
  • Tempering: Tempering temperature: 540-680°C. Forging
  • Hot forming temperature: 1100-850°C.
  • Machinability: Machinability of CK60 and all of the higher carbon steels is relatively poor.
  • CK60 rates at 55 to 60 % that of the AIS11112 steel which is considered 100% machinable Corrosion Resistance
  • This steel is not corrosion resistant, it will rust unless protected.

Welding:
  • CK60 steel is weldable by all of the welding methods. However with its higher carbon content it is important to use both pre-heat at 150 to 260°C and post-heat at 590 to 650°C practice per an approved welding procedure.
  • Cold working is difficult even in the annealed condition although it may be done by conventional methods but requires greater force than the lower carbon steels.

Steel grade S355J2G3 is a low carbon, high strength structural steel which can be readily welded to other weldable steel. With its low carbon equivalent, it possesses good cold-forming properties. The plate is produced by fully killed steel process and supplied in n normalized or controlled rolling condition. S355J2G3 steel has its own features and its use is quite wide. Because of adding Cr, Cu and Ni, oxide layer forms stick firmly on the work piece surface. This oxide layer prevents further corrosion of the steel.

StandardAISI 1045

AISI 1045 steel is a medium tensile steel supplied in the black hot rolled or normalized condition. It has a tensile strength of 570 – 700 MPa and Brinell hardness ranging between 170 and 210. AISI 1045 steel is characterized by good weldability, good machinability, and high strength and impact properties in either the normalized or hot rolled condition. AISI 1045 steel has a low through-hardening capability with only sections of size around 60 mm being recommended as suitable for tempering and through-hardening. However, it can be efficiently flame or induction hardened in the normalized or hot rolled condition to obtain surface hardnesses in the range of Rc 54 – Rc 60 based on factors such as section size, type of set up, quenching medium used etc. AISI 1045 steel lacks suitable alloying elements and hence does not respond to the nitriding process


Machining:
  • AISI 1045 steel has good machinability in normalized as well as the hot rolled condition.
  • Based on the recommendations given by the machine manufacturers, operations like tapping, milling, broaching, drilling, turning and sawing etc.
  • Can be carried out on AISI 1045 steel using suitable feeds, tool type and speeds.

Welding:
  • Certain facts about welding of AISI 1045 steel are:
  • The workpiece is
  • AISI 1045 steel is readily welded when correct procedure is followed.
  • Welding AISI 1045 steel in through-hardened, tempered and flame or induction hardened condition is not recommended.
  • Low hydrogen electrodes are preferred for welding AISI 1045 steel.
  • Pre-heated at 200°C–300°C (392°F – 572°F)
  • Maintained at the same temperature during welding
  • Cooled slowly using sand, ashes etc and
  • Stress relieved at 550°C – 660°C (1022°F – 1220°F).
 

AISI 1045 is subjected to the following processes:

  • Forging
  • Annealing
  • Normalizing
  • Stress relieving
  • Hardening
  • Tempering

Forging:
  • Heat to 850°C – 1250°C (1562°F – 2282°F)
  • Hold until the temperature is uniform
  • Cool in furnace
  • Heat to 800°C – 850°C (1472°F – 1562°F)
  • Hold until the temperature is uniform
  • Cool in furnace.
  • Cold Working
  • AISI 1040 carbon steel can be cold worked in the annealed state using conventional methods

AISI 1020 is a low hardenability and low tensile carbon steel with Brinell hardness of 119 – 235 and tensile strength of 410-790 MPa. It has high machinability, high strength, high ductility and good weldability. It is normally used in turned and polished or cold drawn condition. Due to its low carbon content, it is resistant to induction hardening or flame hardening. Due to lack of alloying elements, it will not respond to nitriding. However, carburization is possible in order to obtain case hardness more than Rc65 for smaller sections that reduces with an increase in section size. Core strength will remain as it has been supplied for all the sections. Alternatively, carbon nitriding can be performed, offering certain benefits over standard carburizing. AISI 1020 steel can be largely utilized in all industrial sectors in order to enhance weldability or machinability properties. It is used in a variety of applications due to its cold drawn or turned and polished finish property.

 

Machining:

  • In the cold drawn or turned and polished condition, AISI 1020 steel has high machinability.
  • As per recommendations of machine manufacturers, AISI 1020 steel can be used for drilling, turning, milling and tapping operations using suitable feeds, tool type and speeds.

Weldability:
  • AISI 1020 can be welded by performing the most common welding processes.
  • In the cold drawn or turned and polished condition, it has better weldability. It has been suggested that the welding process should not be performed in heat treated or carburized condition.

Heat TreatmentAnnealing:
  • AISI 1020 steel is heated at 870°C – 910°C followed by holding for certain time until the temperature remains constant all over the section.
  • It is then cooled in a furnace.

Carburizing:
  • AISI 1020 is heated to between 880°C – 920°C in a suitable carburizing atmosphere followed by holding for sufficient amount of time to produce the needed carbon content and case depth.
  • After this, refining/hardening and tempering processes are carried out to optimize the core and case properties.

30C8 in its heat treated forms possesses good homogenous metallurgical structures, giving consistent machining properties. Good heat treatment results on sections larger than 63mm may still be achievable, but it should be noted that a fall-off in mechanical properties would be apparent approaching the centre of the bar. It is therefore recommended that larger sizes of 30C8 are supplied in the untreated condition, and that any heat treatment is carried out after initial stock removal. This should achieve better mechanical properties towards the core.


PreviousNext Welding:

  • 30C8 bright mild steel contains a lot less carbon then it use to, this mean that it is possible to weld pieces up to 18mm thick without preheating using MIG wire (SG2) or a 7018 electrode.
  • Over 18mm would require a pre-heat of 100°C (212°F) in order to prevent cracking.
  • Anneal afterward is recommended to prevent breaking

Flame Cut Profiles:
  • A hard edge can occur when flame cutting EN8 plate, therefore this grade is commonly normalized after flame cutting.
  • EN8 flame cut profiles can be supplied Lumsden ground or precision ground.

Carbon Steel C 60 Description C 60 steel is one of the higher carbon content (0.60%) steels. It is more difficult to fabricate than the lower carbon grades.

 

Soft Annealing:

  • Heat to 650-700°C, cool slowly in furnace. This will produce a maximum Brinell hardness of 241.

Hardening:
  • Harden from a temperature of 800-830°C, 810-840°C followed by water or oil quenching.

Normalizing:
  • Normalizing temperature (°C): 820-850°C.

Tempering:
  • Tempering temperature: 540-680°C.

Forging:
  • Hot forming temperature: 1100-850°C.

Machinability
:
  • Machinability of C 60 and all of the higher carbon steels is relatively poor. CK60 rates at 55 to 60 % that of the AIS11112 steel which is considered 100% machinable

Corrosion Resistance:
  • This steel is not corrosion resistant, it will rust unless protected.

Welding:
  • C 60 steel is weldable by all of the welding methods. However with its higher carbon content it is important to use both pre-heat at 150 to 260°C and post-heat at 590 to 650°C practice per an approved welding procedure.

Cold working:
  • Cold working is difficult even in the annealed condition although it may be done by conventional methods but requires greater force than the lower carbon steels.

Normalizing:
  • Normalizing temperature: 890°C.

Forging:

  • Hot forming temperature: 1100-850°C.

Machinability:

  • Machinability is good,rated at 60 % that of the AIS11112 alloy steel which is considered 100% machinable Corrosion Resistance
  • This is a steel alloy and will rust if not protected. it is not corrosion resistant Welding
  • CK40 steel is weldable by all of the welding methods. However with its higher carbon content it is important to use both pre-heat at 150 to 260°C and post-heat at 590 to 650°C practice per an approved welding procedure.

Tempering:
  • Tempering from the quenched condition may be done at 320-700°C depending upon the strength desired
