301 Stainless steel coil manufacturer

The 301 stainless steel belt is a kind of metastable austenitic stainless steel with complete austenitic structure under the condition of sufficient solution.

In stainless steel, 301 is the most easily cold deformation strengthening steel grade, through the cold deformation processing can make the strength of steel, hardness, and retain enough plastic and toughness, together with the steel under the condition of the atmosphere with good rust resistance, but the poor corrosion resistance, reducing medium in acid and alkali salt chemical medium corrosion resistance is poorer, therefore is not recommended for corrosion harsh environment.

The 301 is mainly used in cold working condition for equipment parts that bear high loads and want to reduce the weight of the equipment and do not rust.

In addition, this steel is easy to produce work hardening when impacted by external forces and can absorb more impact energy, which will provide a more reliable safety guarantee for equipment and personnel.

The 301 is prone to work hardening during deformation and is used in places requiring higher strength

This is the most cost effective grade of steel. So the 301 Stainless Steel coil Price is lower compared to other grades of stainless steels and all metallic products in general. There are different versions of the material with low carbon and high carbon content.  The low carbon version, 301 coils are very good for welding applications as they have less carbide precipitation and less localized corrosion.

Processing Technology Of 304 Stainless Steel Coil

With the development of science and technology and industry, the materials put forward higher requirements, such as higher strength, resistance to high temperature, high pressure, low temperature, corrosion resistance, wear and other special physical and chemical properties of the requirements, carbon steel has been unable to fully meet the requirements.

Deficiency of carbon steel:

(1) Low hardenability. In general, the maximum quenching diameter of carbon steel water quenching is only 10mm-20mm.

(2) Relatively low strength and buckling. For example, the σ S of ordinary carbon steel Q235 steel is 235MPa, while the σ S of low alloy structural steel 16Mn is more than 360MPa. The σ S /σ B of 40 steel is only 0.43, which is much lower than that of alloy steel.

(3) Poor tempering stability. Because of the poor tempering stability, carbon steel in the quenching and tempering treatment, in order to ensure higher strength to use a lower tempering temperature, so that the toughness of steel is low; In order to ensure better toughness, the strength of high tempering temperature is low, so the comprehensive mechanical properties of carbon steel is not high.

(4) Can not meet the requirements of special performance. Carbon steel in oxidation resistance, corrosion resistance, heat resistance, low temperature resistance, wear resistance and special electromagnetic and other aspects are often poor, can not meet the needs of special performance.
