What is Superior Steel?
Superior steel (between special steel and plain carbon steel, generally does not contain alloy): mainly refers to the mechanical properties of good, and tensile strength, toughness of the comprehensive performance is good, can mechanical properties of good easy to process, heat treatment after mechanical effect significantly improve, from the composition of the steel in the steel less impurities, the gold particles are relatively small and uniform steel.
Common superior steel carbon steel, steel, mold steel, spring steel, steel round, high steel, bearing steel, carbon steel, gear steel, carbon steel, steel, carbon steel, steel, carbon steel, billet steel, roll steel, steel, and so on.

Carbon steel: high-quality carbon structural steel referred to as carbon steel; specifically, its carbon content is less than 0.08%. The use of low carbon steel is rolled sheet, deep-drawn products; carbon steel is used in the manufacture of small-scale rain tempered parts, including tie rods, bushings, gears, piston pins, fasteners, etc.; high carbon steel is used in the manufacture of springs and require wear-resistant parts.
Combined steel used as mechanical parts and various engineering components and contains one or several kinds of a certain amount of alloying elements of steel. Can be divided into general alloy structural steel and special purpose alloy structural steel. Alloy structural steel is widely used in ships, vehicles, aircraft, missiles, weapons, railroads, bridges, pressure vessels, machine tools and other structures.
Mold steel can be roughly divided into (cold work die steel), (hot work die steel) and (plastic die steel) 3 categories, used for forging, stamping, cutting type, die casting, etc..
Spring steels are steels used exclusively for the manufacture of springs and elastic components due to their elasticity in the quenched and tempered condition.
