Product Details:

C40 steel plate is one mainly of high carbon steel, EN 10083 C40 steel plate is meduim Carbon Steels are similar to low carbon steel except that the carbon ranges from 0.30 to 0.60% & the manganese from 0.50 to 1.65%. Increasing the carbon content is approximately 0.5%.

Hardenability:

• Low hardenability; it shows intermediate features between those of steels with medium and those of steels with high carbon content
• Therefore it is not easy to obtain the required features by quenching in oil and the quenching in water can result in cracking.

Product Details:

CK-50 is a Fe-Cr-Ni alloy containing slightly more chromium and considerably more nickel than the CH-20 grade. The alloy is used provides good resistance to dilute sulfuric acid and resists many co rodents more effectively Than CF-8 type. The alloy is fully austenitic and contains chromium carbides throughout the matrix, which are put into solution by High temperature solution anneal, which also improves ductility and strength. The alloy should be solution Annealed to maximize corrosion resistance and after welding to prevent sensitization of the HAZ.

Product Details:

DIN 41Cr4 and DIN 42CrMo4 materials have been widely used in automotive driving elements. Although 42CrMo4 is more expensive than 41Cr4, it is more preferable in terms of material properties. In this study, these two materials were heat treated by austenitizing in a continuous furnace at 850 °C and quenched in oil at 90 °C. After they were tempered at various temperatures, mechanical properties were determined for each tempering temperature. The material properties for both materials were compared with each other. Results indicated that same mechanical properties for 41Cr4 and 42CrMo4 can be achieved by tempering 41Cr4 about 50 °C lower temperature than for 42CrMo4. In addition to the mechanical tests, fatigue tests were performed for both materials. Weibull distributions were plotted. Results indicated that 42CrMo4 had a longer life than 41Cr4 material.
