Carbon Steel Bars

Product Details:

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.

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.

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.
