According to the rolling method, it is generally divided into hot rolled, hot extruded and cold rolled stainless steel tubes.
According to the metallographic structure of stainless steel, it is different from semi-ferritic and semi-martensitic stainless steel seamless pipes, martensitic stainless steel seamless pipes, austenitic stainless steel seamless pipes, austenitic-ferritic stainless steel seamless pipes, etc.
Generally, the common materials of stainless steel seamless pipes are 201. 202. 301. 302. 304. 304L. 321. 316. 310S.
Where Can Seamless Stainless Steel Tube Be Used In?
Generally, seamless pipes are made of high-quality carbon steel structures such as 16Mn, low-alloy steel structures such as 10, 20, 35, 45, or composite steels such as 40Cr, which are hot-rolled or cold-rolled. Seamless pipes made of mild steel such as 10.20 are mainly used for fluid transportation pipelines. Seamless pipes made of medium carbon steel such as 45.40Cr are used to manufacture mechanical parts, such as stressed parts of automobiles and tractors. Seamless tubes for low and medium pressure boilers: used to manufacture various low and medium pressure boilers, superheated steam pipes, boiling water pipes, water wall pipes and locomotive boiler superheated steam pipes, smoke pipes and arched brick pipes.
