Stainless Steel 302 302S25 SUS302 stainless steel plate thickness of 304 bar than 201 good, 201 and 202 quite. By microstructure categories into four categories: austenitic stainless steel ferritic martensitic precipitation hardening stainless steel in stainless steel, outside no less than thousands, it is difficult to prepare the above. 201,202,304 an austenitic stainless steel, steel which is the United States, Japan is preceded by so called SUS. Now part of the austenitic stainless steel grades were tabulated under the United States: the first grade for Chinese GB, American ASTM grade brackets, (/) indicates no corresponding grades. 1Cr17Mn6Ni5N (201), 1Cr18Mn8Ni5N (202), 1Cr17Ni7 (301), 1Cr18Ni9 (302), Y1Cr18Ni9 (303) Y1Cr18Ni9Se (303Se), 0Cr19Ni9, 0Cr18Ni9 (304), 0Cr19Ni10, 0Cr18Ni10 (304L), 0Cr19Ni9N (304N1), 0Cr19Ni10NbN ( 304N2), 0Cr18Ni10N (304LN), 1Cr18Ni12, 1Cr18Ni12Ti (305), 0Cr23Ni13 (309S), 0Cr25Ni20, 0Cr25Ni20Si2 (310S), 0Cr17Ni12Mo2 (316), 0Cr18Ni12Mo2Ti (/) 00Cr17N ...
