Everything You Need to Know About 36CrNiMo4, 817M37, 35NCD5, 4340, 1.6511 Alloy Steel EN 10083-1
1.6511 Alloy Steel Description
1.6511 alloy steel is a medium carbon, low alloy steel. The 36CrNiMo4 alloy steel is known for its toughness and hardness. The pre-hardened 1.6511 alloy steel can be further hardened by flame, induction hardening or nitriding. The steel is specifically used in cases where the other steel grades do not have the hardenability to provide the required strength.
