Many customers are asking about 65Mn spring steel recently. 65mn spring steel, because its elasticity and hardenability are higher than that of No. 65 steel, has a tendency of overheating sensitivity and temper brittleness, and water quenching tends to form cracks. The annealed state can be cut, the cold deformation has low plasticity, and the welding performance is poor.Next, I will introduce some basic information of 65Mn in detail. If you need to purchase 65Mn spring steel, you can compare it to see if it meets your requirements.

Grade: 65Mn
Standard: GB/T 1222-2007
Features and scope of application:
After heat treatment and cold drawing hardening, it has high strength, certain toughness and plasticity; under the same surface state and complete hardening, the fatigue limit is equivalent to that of alloy springs. However, the hardenability is poor, and it is mainly used for springs of smaller sizes, such as pressure-adjusting and speed-regulating springs, force-measuring springs, round and square coil springs on general machinery, or drawn steel wires as springs on small machinery.
