What Are the Spring Washer Materials?

1． spring washers are mainly two kinds of material, one is iron, the other is stainless steel. Iron in general we usually use 65MN spring steel or 70 carbon steel, 3Cr13, also called 65 mammoth. So the iron material is better. Stainless steel, generally has 201, 304, 316. Iron spring washers are required to be electroplated, stainless steel material is not required to plating;

2． introduce why the material of spring washers must be 65MN rigid or 304 stainless steel, mainly due to the advantages of spring washer material and their respective scope of application, such as 65 spring steel performance and 70 spring steel similar, elasticity and strength slightly higher, suitable for the manufacture of small cross-section, strength requirements, general machine round, square spring spring washers, such as cars, tractors or trains and other mechanical vibration flat and coiled coils.

3． gb93 spring washer is 304 stainless steel spring washer good or manganese steel spring washer spring gasket good? In fact, this is also the spring washer material material difference, manganese steel refers to 65 manganese. 65 manganese is a more commonly used spring steel, refers to carbon steel in the higher manganese content of structural steel. In terms of strength, the 304 is only about two-thirds of 65 manganese, but stainless steel is rust-proof. If you must say who is good, can only be determined according to the use!
