60Si2MnA GB /T 5218-1999 alloy spring wire

60Si2MnA alloy spring wire is a kind of high performance spring material, which has a wide range of applications and unique material properties.

Material designation	60Si2MnA
China ISC	A11603
Correspondence standard	GB /T 5218-1999 Alloy spring steel wires
Sort out	Alloy steel
Property	Elastic hardenability
Tag	Spring steel
Instructions	The steel is a widely used spring steel with good hardenability, high strength and elastic limit after quenching + tempering, high yield ratio and anti-relaxation ability, and high tempering stability. However, the decarbonization tendency is large, the cold deformation is poor, and the cutting performance is poor. It is mainly used in the manufacture of various elastic retainers, rings and springs that work below 250°C, with a thickness of less than 10mm and a diameter of less than 25mm. The amount of steel in the fastener industry is smaller than 65Mn, mainly used for the production of various elastic gaskets, rings, pins and other products. Generally not used for the production of bolts, screws, nuts. Selection suggestions: All kinds of elastic washers, pins and clasp, etc., working in a non-corrosive environment, strength 42~54HRC, recommended use.
