301 Stainless Steel Seamless And Welded Pipe With Big Diameter
Product Description
What is stainless steel
Stainless steel is an alloy of Iron with a minimum of 10.5% Chromium. Chromium produces a thin layer of oxide on the surface of the steel known as the passive layer. This prevents any further corrosion of the surface. Increasing the amount of Chromium gives an increased resistance to corrosion.
Stainless steel also contains varying amounts of Carbon, Silicon and Manganese. Other elements such as Nickel and Molybdenum may be added to impart other useful properties such as enhanced formability and increased corrosion resistance.
301 stainless steel is a kind of metastable austenitic stainless steel, which has complete austenitic structure under the condition of full solid solution. Among the stainless steels, 301 is the most susceptible to cold deformation and strengthening. The strength and hardness of the steel can be improved by cold deformation processing,and enough plasticity and toughness can be retained. In addition, this steel has good corrosion resistance under atmospheric conditions, but poor corrosion resistance in reducing media and poor corrosion resistance in chemical media such as acid and alkali salts. Therefore, it is not recommended to be used in harsh corrosive environments.
301 is mainly used in the cold working state for equipment parts that bear high loads and want to reduce equipment weight and not rust. In addition, this steel is prone to work hardening when impacted by external forces, which can absorb more impact energy and provide more reliable safety guarantee for equipment and personnel.
