What are the characteristics of different types of stainless steel spring materials?
Time: December 5, 2019 Source: this station Font:[ large in Small ]

There are several kinds of spring made of stainless steel spring, such as 304 stainless steel spring and 304 stainless steel spring produced by different factories in Zhejiang Province Stainless steel spring What are the characteristics of the material?

 What are the characteristics of different types of stainless steel spring materials?

304 stainless steel spring:

Spring made of 304 stainless steel is also a large number of domestic stainless steel spring. 304 is a chrome nickel stainless steel, divided into three types: mirror, bright and matte. According to the name, we can see that the mirror is the brightest, just like the mirror, which is especially suitable for medical device spring and handicraft spring, because the mirror stainless steel is not easy to stick grease and easy to clean. Compared with the mirror stainless steel spring, the smooth surface of stainless steel is slightly worse. If it is used as a medical device spring, it needs to be polished after the spring is formed. Finally, a lot of matte stainless steel was used. Due to its low cost, the stainless steel has the same mechanical properties and rust resistance as the first two. Therefore, it is widely used in all kinds of springs which need to be rustproof. The recommended service temperature is - 40 ° to 120 ° (it is not recommended to exceed 120 ° otherwise the mechanical properties will be reduced)

302 stainless steel spring:

In fact, it is larger than 304 stainless steel in foreign countries. In terms of mechanical properties, the effect is better than 304 stainless steel spring, but the anti rust ability is slightly lower than 304. Because of the different element contents. But on the whole, it doesn't make much difference. In many cases, if the spring accuracy required by 302 and 304 is not particularly high, other types can be used. The recommended operating temperature is - 40 ° to 120 ° (it is not recommended to exceed 120 ° otherwise the mechanical properties will be reduced). The recommended operating temperature is - 40 ° to 120 ° (it is not recommended to exceed 120 ° otherwise the mechanical properties will be reduced).

301 stainless steel spring:

301 stainless steel spring is equivalent to "stainless steel piano wire". The elasticity and fatigue are much higher than the former two, so it is very suitable to be used when the conventional stainless steel spring (such as 302 ~ 304 spring) can not meet the force requirements. The recommended service temperature is - 40 ° to 120 ° (it is not recommended to exceed 120 ° otherwise the mechanical properties will be reduced)

316 stainless steel spring:

316 stainless steel spring is more suitable for use in seawater than other types of stainless steel, and has better corrosion resistance than other grades of stainless steel. It also has low magnetism. The recommended service temperature is - 40 ° to 120 ° (it is not recommended to exceed 120 ° otherwise the mechanical properties will be reduced)

631 stainless steel spring:

631 stainless steel spring is a kind of semi austenitic precipitation hardening stainless steel, which is widely used in mechanical and medical fields. It has strong corrosion resistance, toughness and high fatigue resistance. Especially for the high temperature resistance, 631 spring is different from other stainless steel and can be used between - 40 ° and 380 °. In many cases, it is used as heat-resistant spring steel.
