Alloy quenched and tempered steel
41Cr4 / 1.7035 alloy engineering steel
41Cr4 is chromium-alloyed quenched and tempered steel. Closer to C45 in carbon, with chromium for hardenability — without the Mo addition in 42CrMo4.

Limits
42CrMo4 when the section or strength requirement calls for molybdenum.
Delivery
We source 41Cr4 from European mill partners as round bar, flat bar, square bar, cut to your dimensions and ship the certificate with the material. Typical condition: +QT. From a single cut piece to larger lots — with no minimum charge, so you do not have to buy a full commercial length to get what you need.
Certificates and documentation
41Cr4 can be supplied with a material certificate to EN 10204, depending on producer, dimension and the requirements specified for the delivery. The condition is what the certificate has to carry on 41Cr4: as-rolled, +N and +QT are not the same product, and if a hardness or strength is to be documented in the delivered dimension, the requirement belongs on the enquiry. EN 10204 3.1 can be supplied on a wide range of our materials.
