Did you try 42CD4 steel

A french friend sent me an inquiry about 42CD4 steel about 2 years ago,I was so confuse at that time

A french friend sent me an inquiry about 42CD4 steel about 2 years ago,I was so confuse at that time,I think I never heard this kind of material.and told him that 42CD4 steel we don’t have.
Lately,I got the inquiry of 42CD4 steel again,but I check the chemical component this time,It’s Din 42CrMo4 similar steel,how stiup i was 2 year ago,42CD4 steel is the french standard,42CrMo4 is the germen standard.I had been this company for 3 year,finnaly I got experience about steel,and this time I sure would do the same mistake,I told the french customer about 42CD4 steel information,and share the stock data with him.

If you want to know more about 42CD4 steel,you are welcome contact me.

42CD4 alloy steel Heat treatment
Annealing
AISI 42CD4 alloy steel is annealed at 872°C (1600°F) followed by slowly cooling in the furnace.
Tempering
AISI 42CD4 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has lower tempering temperature. For example, tensile strength of 225 ksi cab be achieved by tempering at 316°C (600°F), and a tensile strength of 130 ksi can be achieved by tempering at 538°C (1000°F).
Hardening
AISI 42CD4 alloy steel can be hardened by cold working, or heating and quenching.
