304 Stainless steel coil manufacturer

Stainless Steel 304 coil is made up of an austenitic stainless steel that has 18% chromium and 8% nickel in the composition. This is the most used grade of all stainless steels in the world. The coils are strong, mild corrosion resistant and have applications in a variety of industries. The Stainless Steel 304 coil also has manganese, carbon, silicon, sulfur, nitrogen and phosphorus in the composition. The material is strong and has 205MPa minimum yield strength and 515MPa minimum tensile strength in general.

The thinner coils have higher strength values. The specification of the coils is the A240 for pressure vessel and high temperature applications. The ASTM A240 SS 304 coil can withstand high temperatures up to 870 degrees Celsius. The coils are used for this reason in evaporators, heat exchangers and in other high temperature applications. The Stainless Steel 304 coil is also used in drums, barrels, dairy equipment, food processing and in hospital equipment.

This is the most cost effective grade of steel. So the 304 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 coils and UNS S30400 Stainless Steel Strip Specification varies and the applications differ for the different versions of the material. The low carbon version, 304L coils are very good for welding applications as they have less carbide precipitation and less localized corrosion. The ASME SA240 Stainless Steel 304 Coil Thickness ranges up to 200mm and the width and the length ranges widely depending on the application requirements as well.

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.
