Stainless Steel Coil 304

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.
