JIS G3444 Standard Overview
• JIS G3444 is a technical specification for carbon steel tubes for general structural use in the Japanese Industrial Standard (JIS), the latest version is JIS G3444:2015. The standard specifies the chemical composition, mechanical properties, dimensional tolerances, detection methods and other requirements of the steel pipe, and is suitable for construction, machinery, scaffolding and other structural purposes.
STK500, one of the material grades defined in the standard, is a high-strength carbon steel designed for load-bearing structures, especially for Scaffolding pipes.
Material Characteristics
Chemical Composition
• Carbon (C) : ≤0.24%
• Silicon (Si) : ≤0.35%
• Manganese (Mn) : 0.3%-1.3%
• Phosphorus (P), sulfur (S) : both ≤0.04%.
Mechanical properties
• Tensile strength: ≥500 MPa
• Yield strength: ≥355 MPa
• Elongation (δ5) : ≥17%
• Hardness (HBS) : 123-321.
• Corrosion resistance: formed by Black Annealing (Black Annealing) oxidation layer, with a certain anti-corrosion ability.
