SPHC steel is a commercial quality hot rolled steel that defined in JIS G 3131 standard. JIS G3131 SPHC Steel is usually used in various applications of Construction including Ship Plate, Wear Resistant Steel and Container Plate, also extensively used in some of the automotive manufacturing, electric products, vehicles, aviation.
The Chemical Composition of SPHC Steels
Maximum percentage ofCarbon(C) is0.15percent.
Maximum percentage ofManganese(Mn) is0.60percent.
Maximum percentage ofPhosphorous(P) is0.050percent.
Maximum percentage ofSulphur(S) is0.050percent.
Remaining isIron(Fe) percentage and with few negligible impurities.

Remaining isIron(Fe) percentage and with few negligible impurities.
The tensile strength of the SPHC Steels is expressed in Newton per millimeters and it must be at-least 270 N/mm2 (MPa). The elongation property of SPHC steel varies with the ranges of thickness. The minimum percentage ranges for elongation is from 27 to 31 percent starting from 1.2 mm to 4 mm and over.
