Analysis of why 304 stainless steel failure must be selected by the manufacturer of stainless steel failure
There are various types of stainless steel, with the more common being the 200 series, 300 series, and 400 series The professional classification of stainless steel is based on crystal structure, including ferritic stainless steel (430, ETC.), martensitic stainless steel (410, ETC.), austenitic stainless steel (304, ETC.), etc
304 is a common raw material in stainless steel, with high temperature resistance, good processing performance, and high resistance It is recognized as a category that can be directly touched with food The common labeling methods for 304 stainless steel in the market include 06Cr19Ni10, SUS304, etc. Among them, 06Cr19Ni10 generally represents national standard production, SUS
304 representatives Japanese standard production The 304 stainless steel faucets currently solid online are generally labeled as 304 or SUS 304
The chemical formula of 201 stainless steel is 1Cr17Mn6Ni5, and its primary difference from 304 is the nickel chromium element 201 has 17 chromium and 5 nickel, while 304 has 19 chromium and 10 nickel 201 is an industrial raw material with certificate acid and alkali resistance, but its overall performance is far inferior to 304 201 is mainly used in the manufacturing of decoration pipes, industrial pipes, and some shallow striped products
Nowadays, counterfeit 304 stainless steel failures on the market are mostly made of 201 stainless steel Because 201 stainless steel contains manganese, it will trust in humid and salt air for a long time, while 304 stainless steel does not have manganese, so it will not trust Theoretical, if your stainless steel fails trusts, it provides that its raw material is not 304 stainless steel, and it is like that it is a product counterfeit by scrupulous transactions using 201 stainless steel
There is also data showing that the current price of 304 is 20000 yuan/ton, while 201 is 15000 yuan/ton, which means that the product of 201 is only 25% higher than 304 product This is why scrupulous transactions are replacing 304 with 201 one after another
