310S is an austenitic chromium-nickel stainless steel has good oxidation resistance, corrosion resistance, because a higher percentage of chromium and nickel, 310S has a much better creep strength at high temperature continuous operation, has good high temperature sex. 310S stainless austenitic chromium-nickel stainless steel, 310S stainless steel has good oxidation resistance, corrosion resistance, because a higher percentage of chromium and nickel, so that has a much better creep strength at high temperature continuous operation, with good temperature resistance. Due to nickel (Ni), chromium (Cr) content is high, with good resistance to oxidation, corrosion, acid and alkali, high temperature resistance, high temperature electric furnace steel pipe dedicated to the manufacture of pipes and other occasions, austenitic stainless steel increased carbon After content, due to its solid solution strengthening effect of the strength increase, the chemical composition of the characteristics of austenitic stainless steel is chrome, nickel-based add molybdenum, tungsten, niobium and titanium and other elements, because of its organization as a face-centered cubic structure, Thus in the high temperature strength and creep strength. Melting point 1470 ℃, 800 ℃ begins to soften, allowable stress continues to decrease. 310S stainless steel chemical composition: C: ≤0.08, Si: ≤1.00, Mn: ≤2.00, P: ≤0.045, S: ≤0.030, Ni: ≤19.00-22.00, Cr: ≤24.00-26.00 mechanical properties of stainless steel 310S: Hardness (HB): ≤187 Tensile strength (бb) (Mpa): ≥520 yield strength (σs) (Mpa): ≥205 elongation (δ)%: ≥40 reduction of area (ψ)%: ≥50 Stainless Mechanical properties 310S is: ób (MPa) ≥520, ó0.2 (MPa) ≥205, δ5 (%) ≥40, Ψ (%) ≥50, HB≤187 above 1150 ℃ high temperature capability. Melting point 1398 ℃ ~ 1454 ℃ Uses: stamping dies, jigs, tools, gauges, knife, auxiliary tools. Features: carbon tool steel is usually easy to improve the fragmentation of nature, and achieve longevity of the tool. Vacuum degassing refining steel, quality and stability. Good hardenability, oil cooling hardened (quenching crack and less deformation) toughness and good wear resistance, durable tool. Heat treatment: Quenching: 500 to 550 810 to 830 Tempering: 180 to 200 in the annealed condition, ≤207HB, indentation diameter ≥4.20mm quenching, ≥62HRC
