SGCC steel is a hot-dip galvanized steel commonly used in the manufacture of various metal products and components. The following are the general chemical composition and mechanical properties of SGCC steel:
The chemical composition of SGCC steel is generally as follows:
- Carbon (C) content: ≤0.15%
- Manganese (Mn) content: ≤1.00%
- Phosphorus (P) content: ≤0.035%
- Sulfur (S) content: ≤0.025%
- Iron (Fe) content: allowance
- Zinc (Zn) coating weight percentage: usually 275 g/ m2 (g/m²)
It is important to note that these chemical compositions are general indicators of SGCC steel, and specific chemical compositions may vary as they may be affected by changes in the manufacturer, product specifications and production process. In the specific application, it is best to refer to the product specifications or technical materials provided by the supplier to obtain accurate chemical composition information.
The mechanical properties of SGCC steel include the following:
1. Yield strength (YS) : The yield strength of SGCC steel is usually 205 MPa or above. Yield strength is the level of stress at which a material begins to produce plastic deformation during stretching.
2. Tensile strength (TS) : The tensile strength of SGCC steel is usually 270 MPa or above. Tensile strength is the maximum level of stress that a material can withstand during stretching.
3. Elongation (EL) : The elongation of SGCC steel is usually 22% or more. Elongation represents the ability of a material to undergo plastic deformation before breaking, and is a measure of the ductility of a material.
4. Hardness: The hardness of SGCC steel may vary depending on the specific treatment and heat treatment conditions, usually in a low range. Common hardness testing methods include Brinell hardness (HB) and Rockwell hardness (HRC).
It is important to note that the mechanical properties of SGCC steel may vary by manufacturer, product specification and production process. The exact mechanical performance parameters are best obtained from the product specifications or technical data provided by the supplier.
