Please recommend a hardware spring manufacturer? It is best to be near Dongguan.

High temperature resistant spring is a spring made of special material, which can adapt to the high temperature environment of 300-950℃. High temperature resistant compression spring, high temperature resistant tension spring, high temperature resistant torsion spring, high temperature resistant die spring, high temperature resistant disc spring, etc.

Generally, the materials of high temperature resistant springs are CrSi, CrV, Inconel, gh series, etc. The recommended maximum service temperature of superalloy materials is 300℃~950℃.

The temperature below 250℃ can also be made of stainless steel. Suitable materials can be selected according to the use requirements, so as to control the product price and cost.

1) t 631j1t 631used for heat-resistant springs and springs with high tensile strength after heat treatment;

2)630 stainless steel is precipitated, quenched and martensite. This brand has the characteristics of high strength, high hardness and corrosion resistance. After heat treatment, the mechanical properties of the product are more perfect, and the compressive strength can be as high as1100-1300mpa (160-190ksi).

Dongguan Ruizeng Spring Factory can do it, hoping to help you.
