Chisel tool steel
Generally used to manufacture various tools, such as carbon tool steel, alloy tool steel, high-speed tool steel, etc. According to the purpose, it can also be divided into cutting tool steel, mold steel and measuring tool steel.
Special steel
Steel with special properties, such as stainless steel and acid-resistant steel, heat-resistant and non-peeling steel, high-resistance alloy, wear-resistant steel, magnetic steel, etc.
Special steel
This refers to professional steel used in various industrial sectors, such as automobiles, agricultural machinery, aviation, chemical machinery, boilers, electrical engineering, welding rods, etc.
According to the quality of steel
High-quality carbon structural steel, alloy structural steel, carbon tool steel and alloy tool steel, spring steel, bearing steel, etc.
The symbol "A" or the Chinese character "high" is usually added after the steel grade for identification.
