W NR1 8159 What steel can be substituted

Spring steel

Standard:

en 10083-3 : 2006

Features & Applications:It has good mechanical properties and process properties, high hardenability, adding vanadium to refine the grain of steel, reduce overheating sensitivity, improve strength and toughness, have high fatigue strength, yield ratio is also high, but poor weldability, low plasticity due to cold deformation.

It is a high-grade spring, which is used as a high-load important spring with a large cross-section and a valve spring, piston spring, and safety valve spring with an operating temperature of <300.

There is no one material that can replace it, and it is not two materials that can be replaced.

Corresponding: domestic 45 steel.

Buderus Buderus cutting steel, also known as Buderus 1730 unalloyed tool steel, is suitable for machining and welding, also known as M 2, fast cutting and easy machining, suitable for large models. The blow mold has excellent wear resistance and heat resistance of the mold base with low stress, frame, general plastic materials, and 1730 mold steel.

Uses: Suitable for domestic and imported enameling machine coating lines.
