GENERAL CHARACTERISTIC

The incorporation of molybdenum during the alloying process enhances the corrosion resistance of China Stainless Steel 31This stainless steel variant is comparable to Type 304 and is nearly as widely used in commercial applications, with notable differences including increased strength at higher temperatures and improved corrosion resistance, particularly in chloride environments. Renowned for its excellent weldability, machinability, and outstanding pitting resistance, China Stainless Steel 316 is ideal for the fabrication of pressure vessels and heat exchangers. Type 316L, a low carbon version of Type 316, effectively minimizes carbide precipitation during welding, making it a preferred choice among suppliers and factories seeking reliable materials.

    General Characteristic

    The introduction of molybdenum in the alloying process improves the corrosion resistance of China Stainless steel-316. It is very similar to Type 304 and is almost as commercially popular – the main differences are that the alloy is stronger at elevated temperatures and corrosion resistance is better, especially in chloride environments. With excellent weldability, good machinability and excellent pitting resistance, China Stainless steel-316 is used in the fabrication of pressure vessels and heat exchangers. Type 316L is a low carbon version of Type 316 which minimizes carbide precipitation due to welding.

    Frequently Asked Questions

    What is the main difference between 316 and 304 stainless steel?
    The main difference is the addition of molybdenum in 316 stainless steel, which significantly improves its corrosion resistance, especially in chloride-rich environments, and makes it stronger at elevated temperatures compared to 304.
    What are the mechanical properties of 316 stainless steel?
    China Stainless steel-316 has a tensile strength (Rm) of 510 MPa, a 0.2% proof strength (Rp0.2) of 320 MPa, and a minimum elongation at fracture (A) of 25%.
    Why is 316L stainless steel preferred for welding?
    Type 316L is a low-carbon version of Type 316. The reduced carbon content minimizes harmful carbide precipitation during the welding process, ensuring excellent weldability and maintaining corrosion resistance in welded structures.
    What are the typical applications for 316/316L stainless steel?
    It is commonly used in fabricating pressure vessels, heat exchangers, chemical containers, food preparation equipment, furnace parts, valves, and pumps due to its high corrosion and pitting resistance.
    What is the chemical composition of 316/316L stainless steel?
    It contains ≤0.08% Carbon (C), ≤0.65% Silicon (Si), 1–2.5% Manganese (Mn), 11–14% Nickel (Ni), ≤0.03% Phosphorus (P), ≤0.03% Sulfur (S), 18–20% Chromium (Cr), 2–3% Molybdenum (Mo), and ≤0.75% Copper (Cu).
