JIS G 3302 SGCC Galvanized Cold Rolled Steel

JIS G 3302 SGCC Galvanized Cold Rolled Steel

What is SGCC Steels?

SGCC steel is a soft forming quality hot dip galvanized steel. SGCC is a material grade and designation defined in JIS G 3302 standard. JIS G 3302 is a Japanese material standard for hot dip galvanized steels. The commercial quality hot dip galvanized steel is a type of steel that can be made after galvanizing a coil of SPCC cold rolled material. The Zinc coating thickness is based on the thickness and width and is governed by JIS G 3302.

Dimensional Characteristics of SGCC Steels: The applicable thickness for this SGCC material as defined in the JIS G3302 starts from 0.12 mm to 3.2 mm. However, the width of SGCC material ranges to over 1600 mm.

The Chemical Composition of SGCC Steels: JIS G 3302 defines the chemical composition of SGCC steels as under:

Maximum percentage of Carbon (C) is 0.15 percent.

Maximum percentage of Manganese (Mn) is 0.80 percent.

Maximum percentage of Phosphorous (P) is 0.050 percent.

Maximum percentage of Sulphur (S) is 0.080 percent.

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

Mechanical Properties of SGCC Steels: The tensile strength of the SGCC Steels is expressed in Newton per millimeters and it must be at-least 270 N/mm2 (MPa).

The elongation property of SGCC is not defined.

The hardness of SGCC material is also not exactly defined in JIS G 3302; however as per understanding it should be less that 65 HRB.

Applications of SGCC & Commercial Hot dip galvanized steels: SGCC Steels are mainly used in making the bodies of many types of equipment. These equipments can be related to any sector. Also SGCC steels are used in construction application for example industrial profile structures are made up of SGCC steels.
