Special steel and there is no uniform definition of the concept of special steel is generally considered to have a special chemical composition (alloying), using a special production process, with a special organization and performance to meet the special needs of the steel type. Compared with ordinary steel, special steel has a higher strength and toughness, physical properties, chemical properties, biocompatibility and process performance.
China and Japan, the EU definition of special steel closer, into the special steel quality carbon steel, alloy steel, high alloy steel (alloying elements greater than 10%) three categories, including steel and high-alloy special steel production accounted for 70%. The main advantages of special steel carbon structural steel, carbon tool steel, carbon spring steel, alloy spring steel, alloy steel, ball bearing steel, alloy tool steel, high alloy tool steel, high speed tool steel, stainless steel, heat-resistant steel , and high-temperature alloys, precision alloy, electric alloy. There are nearly 2,000 special steel grades, about 50,000 varieties and specifications in the world currently. In addition to a wide range of special steel outside, in the specification with ordinary steel also showed different characteristics. In addition to plates, tubes, wire, strip, rods and profiles outside, as well as composite materials, surface alloying material, surface treatment material, forging materials, precision casting, powder metallurgy products.
