Material properties: Steel code-named - is a kind of martensite precipitation stainless steel. The steel has high strength and sufficient toughness. After aging treatment, the tensile strength can generally be increased by ~3. Compared with carbon spring steel wire, it is equivalent to The strength of the steel wire. Adding setting tempering can stabilize the low strength and deformation caused by cutting single pieces, joining and trimming after winding the spring. After heat treatment, if the steel is used at 3~℃, it will tend to become brittle. Using stainless steel to make springs can meet the special performance requirements of certain products. Therefore, its materials and manufacturing process are relatively special.
Chemical composition
The chemical composition (mass fraction) of the steel: ,.,.,.~.,.~.,.~.,.3,.3.
Secondary Aging Specification
After heating at ℃, solid solution treatment, and then adjustment treatment at ℃, air cooling, and then aging treatment at ℃. If higher plasticity and toughness are required, the time and temperature can be increased to ℃.
Cold treatment and aging specifications
After heating at ℃, solid solution treatment, then adjustment treatment at ℃, air cooling to room temperature, cold treatment at ℃, and finally aging treatment at ℃.
Specifications for solid solution and aging treatment
The solid solution treatment temperature is ℃, plastic deformation treatment is carried out at room temperature, and finally aging treatment is carried out. Aging temperature ℃, aging.
Typical application examples
) Springs that require normal operation under corrosive combustion gas conditions.
) requires a spring that cannot be disassembled during use.
3) Due to the compact structure, the geometric size of the spring is limited, and the working stress of the spring far exceeds the design allowable limit.
) Important spring that works frequently (~ times/).
