Steel is a general term for iron-carbon alloys with a carbon content between 0.02% and 2.11% by mass.
In addition to iron and carbon, the main elements of steel include chromium, manganese, molybdenum, nickel, silicon, tungsten and vanadium.
Steel has good toughness, high plasticity, good machinability, thermal conductivity, and good heat treatment, so it is one of the most commonly used materials for precision parts processing.
Based on the unique properties of various metal alloys in steel alloys,
we tailor our manufacturing processes to maximize production efficiency and maintain a high level of customer satisfaction.

According to the usage

According to the usage, steel can be divided into structural steel, tool steel, special steel, and dedicated steel.

According to Structural steel properties , structural steel can be divided into：
1) Structural steel for construction engineering, referred to as construction steels, is generally used to make metal structure parts in buildings, bridges, ships, boilers, or other projects. Such as carbon structural steel, low alloy steel, reinforcement steel, etc.
2) Structural steel for machinery manufacturing is used to manufacture structural parts on mechanical equipment. This kind of steel is high-quality steel or high-grade steel, mainly including high-quality carbon structural steel, structural alloy steel, free-cutting structural steel, spring steel and rolling bearing steel.
Tool steel is generally used to manufacture various tools, such as carbon tool steel, alloy tool steel, high-speed tool steel, etc.
According to tool steel properties, it can also be divided into cutting tool steel, mould steel and measuring tool steel according to the purpose.
Special steel has unique properties, such as stainless acid-resistant steel, heat-resistant non-peeling steel, high cathode alloy, wear-resistant steel, magnetic steel, etc.
Professional steel is used for professional purposes in various industrial sectors, such as steel for automobiles, agricultural machinery, aviation, chemical machinery, boilers, electricians, welding rods, etc.
