SCr440 Quality Alloy Carbon Steel Plate

SCr440 alloy steel is a structural alloyed steel which contains 1.0% Cr as per JIS G4104 standard . Compared with S40C steel,it has better strength and hardenability,but may crack when welding. Quality Alloy Steel Plate Chemical composition: Grade C Si Mn P S Ni Cr Cu SCr440 0.38-0.43 0.15-0.35 0.6-0.9 max 0.03 max 0.03 max 0.25 0.9-1.2 max 0.3 Alloy Steel Plate also is carbon steel plate, when other elements comprising metals and non-metals are added to mild steel, alloy steel is formed. These alloy steels display various environmental, chemical and physical properties that can vary with the elements used to alloy. Here the proportion of a…
