What is high temperature resistant spring?

by:Yongqiang     2020-09-09
Always strong for everyone to explain high-temperature spring, is the unique materials produced, to adapt to the environment of high temperature of the spring.


high temperature resistant stainless steel spring, high temperature resistant, high temperature resistant compression spring tension spring torsional spring, high temperature resistant, high temperature resistant mould spring, high temperature resistant disc spring, etc.





high temperature resistant materials in the spring are usually CrV, CrSi, high temperature alloy Inconel material recommended maximum application temperature 300 ℃ ~ 950 ℃, and select suitable materials according to the application of rules.


1. T631J1 / T631 to hot spring and after heat treatment with high intensity of the spring.


2. 630 stainless steel is precipitation, water quenching, martensite stainless steel, and the grade with high strength, hardness and corrosion resistance characteristics. After heat treatment, the mechanical properties of the products more perfect, can reach as high as 1100 - 1300mpa( 160 - 190ksi) The compressive strength. This level can not be used to higher than 300 ℃, 570F) Or very low temperatures, in the atmosphere and dilute acid or its salt have good corrosion resistance, its corrosion resistance is the same as the 304 and 430.


3. High temperature resistant spring 400 ~ 650 ° material selection, GH4145, MonelK500 GH4169 was investigated, Inconel718, InconelX750 etc. ,
