SGC440 Steel Chemical Composition,SGC440 Steel Mechanical Properties steel plate

SGC440 steel is a material grade and designation defined in JIS G3302 standard. JIS G3302 is a Japanese material standard for Galvanized steel plates, sheets, strips for structural, commercial and drawing usage.

SGC440 steel is a high tensile structural hot dip galvanized cold rolled steel in the form of plates, sheets & strips for structural usages.

SGC440 Steel Chemical Composition : JIS G 3302 defines the chemical composition of SGC440 steels as under:

Carbon (C) is maximum 0.25 percent in the standard.

Manganese (Mn) is maximum 2 percent in the standard.

Maximum percentage of Phosphorous (P) is 0.20 percent.

Maximum percentage of Sulphur (S) is 0.050 percent.

Remaining is iron (Fe) percentage and with few negligible impurities.

SGC440 Steel Mechanical Properties: The tensile strength of the SGC440 Steels is expressed in Newton per millimeters and it must be at-least 440 N/mm2 (MPa). The yield strength is minimum 335 N/mm2 (MPa). The elongation property of SGC440 steel varies with the ranges of thickness. The minimum percentage ranges for elongation is 18 minimum.

Dimensional Characteristics of SGC440 Steels: The applicable thickness for this SGC440 material as defined in the JIS G3302 starts from 1.6 mm to 3.2 mm. However the width of SGC440 material ranges to 950 to 2000 mm.

SGC400 is another low tensile structural quality material defined in JIS G3302; this material can be compared with its mechanical properties & chemical composition by SGC440 steel. SAPH440 Steel is a hot rolled structural quality steel & can be used as a reference for comparison.
