Carbon tool steel to the T8 SK6 and SK5 carbon tool steel, mold steel, nonferrous metal · · ·, carbon tool steel the T8 SK6 SK5 carbon tool steel, carbon tool steel, the T8 SK6 and SK5 carbon tool steel quality assurance, materials prove to have a domestic imports have, the nature and purpose of the alloy steel 
 Steel generally can be divided in accordance with its refined method the Bei Simai converter steel (Bessemer converter), alkaline converter steel, open-hearth steel, electric steel. 
 According to its components can be divided into carbon steel, low alloy steel, high alloy steel. 
 Their product shape is divided into steel (section), the steel rod (bar), steel plate (plate). 
 For a specific purpose, the addition of various alloying elements of special alloy steel (special alloy steel), referred to special steel. 
 The nature and purpose of the following special alloy steel for a rough description. 
 (1) high-temperature steel (high-temperature steel) used in the manufacture of boiler. Continuous use temperature of 500 ° C to 600 ° C, to maintain its mechanical properties. Copper is the main alloying elements of high-temperature steel. 
 (2) heat-resistant steel (heat-resistant steel). Chromium, nickel and silicon make the steel resistant to high temperature of 1300 ℃ in the steel. Such steel is usually used in the manufacture of industrial furnaces and resistance wire. 
 (3) stainless steel (stainless steel), add a small amount of copper in steel can delay the corrosion rate of steel in the air. Plus more than 12% chromium steel can avoid steel corrosion. If addition of nickel corrosion resistance and better, and improve the steel Le Xing. The food industry and chemical industry is the extensive use of stainless steel. Kitchen utensils, cutlery and surgical appliances are stainless steel. 
 (4) (Tool, steels) tool steel tool steel carbon content higher than that of structural steel, usually used for saw blades, drill bits, and so on. Special Steel added alloying elements of chromium, tungsten, cobalt, molybdenum, vanadium, and appropriate heat treatment. The following types of steel and uses a simple table for readers' reference. We can see from the above table are many types of steel, while a variety of finished steel has its own special purposes; thus the iron and steel industry is a wide scope of industrial to comprehensive development of the iron and steel industry, in fact, a quick fix may.
