  • Medium Carbon Steel
    Medium Carbon Steel

    Medium carbon steel has a certain degree of plasticity, toughness, strength, and good machinability after quenching as well as cutting performance but has poor welding performance. Strength and hardness higher than low carbon steel, plasticity and toughness lower than low carbon steel. Hot-rolled and cold-drawn materials can be used without heat treatment, and they can also be used after heat treatment. The medium carbon steel has good comprehensive mechanical properties after quenched and tempered, so medium carbon steel is most widely used in various uses of medium strength level, in addition to being used as a building material, it is also widely used for manufacturing various mechanical parts. Such as air compressors, pistons of pumps, impellers of steam turbines, shafts of heavy machinery, worm gears, gears and parts with wear-resistant surfaces, such as: crankshafts, machine tool spindles, rollers, fitter tools, etc.


  • Low Carbon Steel
    Low Carbon Steel

    Low carbon steel is a carbon content of less than 0.25%. It is also called mild steel due to its low strength, low hardness and softness. It is the most common form of steel on the market, and its material properties are acceptable for many applications. Mild carbon steel contains about 0.05-0.25%, which makes it ductile and has relatively low tensile strength and is easy to form. Some carburized and other heat treatments can be used for mechanical parts requiring wear resistance.Low carbon steel has the characteristics of short tempering time, softness, stamping resistance and ductility. It easily accepts for various processing such as forging welding and cutting. It is commonly used in the manufacturer of steel bar, stamping parts, chains, rivets, bolts, wire, etc.


  • High Carbon Steel
    High Carbon Steel

High carbon steels are commonly used for the manufacture of the general bearings, cutting tools, rails, steel frame mode, steel doors and so on.


  • Free Cutting Steel
    Free Cutting Steel

    Free machining steel is steel that forms small chips when machined. This increases the machinability of the material by breaking the chips into small pieces, thus avoiding entanglement in the machinery. This enables automatic equipment to run without human interaction. Free machining steel with lead also allow for higher machining rates. Free machining steel costs 15 to 20% more than a standard steel, but this is made up by increased machining speeds, larger cuts, and longer tool life.

  • SS400
    SS400
    Low Carbon Steel

    SS400 according to material grade and name defined in the JIS G 3101 standard, The first S stands for "Steel", the second S stands for "Structure", and 400 for the lower limit tensile strength of 400 MPa. Ordinary structural steel with a tensile strength of 400 Mpa.This steel is the most widely used in JIS standard. Its use covers structures such as bridges, ships, vehicles, etc., in the shape of steel plates, steel bars and sections, almost all auxiliary materials for machinery and structures are used.SS400 is also soft in hardness due to its low carbon content.
