310S

Product Origin:Sweden Outokumpu/South Africa/Japan Nippon Steel

Execution Standard:ASTM A240/ASME SA-240, ASTM A276, ASTM A182/ASME SA-182, ASTM A312/ASMES A312

Main Components:Carbon (C) ≤ 0.08, Manganese (Mn) ≤ 2.0, Nickel (Ni) 19.0～20.0, Silicon (Si) ≤ 1.5, Chromium (Cr) 24.0～26.0, Sulfur (Mo) ≤ 0.030, Phosphorus (P) ≤ 0.045

Physical Properties:310S stainless steel has excellent high-temperature resistance. It begins to soften when the temperature exceeds 800°C, and allowable stress starts to decrease continuously. The maximum service temperature is 1200°C. Due to its high nickel (Ni) and chromium (Cr) content, it has good oxidation resistance, corrosion resistance, acid and alkali resistance, and high-temperature resistance. High-temperature stainless steel pipes are used specifically for manufacturing electric furnace tubes. After increasing the carbon content in austenitic stainless steel, its strength is enhanced due to solid solution strengthening. The chemical composition characteristics of austenitic stainless steel are based on chromium (Cr) and nickel (Ni) with the addition of elements such as molybdenum (Mo), tungsten (W), niobium (Nb), and titanium (Ti). Its structure is face-centered cubic, thus exhibiting high strength and creep strength at high temperatures.

Mechanical Properties:Tensile Strength: σb ≥ 515Mpa, Yield Strength σb ≥ 205Mpa, Elongation: δ ≥ 35%, Hardness ≤ 310 (HB). It has strong resistance to overall corrosion from formic acid, acetic acid, etc.
