Spring steel made of stainless steel flange is classified according to the chemical composition of stainless steel flange,
Spring steel made of stainless steel flange can be classified into many categories. Today, we mainly introduce the classification according to the chemical composition of stainless steel flange,
According to gb/t 13304 standard of stainless steel flange material, spring steel is divided into non alloy spring steel (carbon spring steel) and alloy spring steel according to its chemical composition.
The carbon content (mass fraction) of carbon spring steel made of stainless steel flange is generally 0.62% - 0.90%. According to the manganese content of stainless steel flange material, it is divided into general manganese content (mass fraction) (0.50%~0.80%), such as 65, 70, 85 and higher manganese content (mass fraction) (0.90~1.20%), such as 65Mn.
Alloy spring steel made of stainless steel flange is a steel that improves the mechanical properties, hardenability and other properties of steel by adding one or several alloy elements on the basis of carbon steel, so as to meet the properties required for manufacturing various springs.
The basic composition series of alloy spring steel made of stainless steel flange include silicon manganese spring steel, silicon chromium spring steel, chromium manganese spring steel, chromium vanadium spring steel, tungsten chromium vanadium spring steel, etc. On the basis of these series, some brands of stainless steel flange materials have added molybdenum, vanadium or boron and other alloy elements to improve their performance in some aspects.
In addition, some grades are selected as spring steel from other stainless steel flange materials, such as high-quality carbon structural steel, carbon tool steel, high-speed tool steel, stainless steel.
