1Cr18Ni12Mo3Ti 1Cr18Ni12Mo3Ti austenitic stainless steel Name: Stainless steel bar Grade: 1Cr18Ni12Mo3Ti Standard: GB / T 1220-1992 ● Features and Scope: 1Cr18Ni12Mo3Ti is acid-resistant austenitic stainless steel, molybdenum steel higher than 1Cr18Ni12Mo2Ti, so rare, phosphatase and organic acids, alkali and corrosion resistance in marine atmosphere further increase in the use of more stringent conditions, good resistance to intergranular corrosion. 1Cr18Ni12Mo3Ti stainless steel for the manufacture of resistance, phosphoric acid, formic acid, acetic acid equipment. In addition to this grade-specific, but generally not recommended. ● Chemical Composition: C: ≤ 0.12 Si Si: ≤ 1.00 Manganese Mn: ≤ 2.00 S S: ≤ 0.030 P P: ≤ 0.035 Cr-Cr: 16.00 ~ 19.00 Ni-Ni: 11.00 ~ 14.00 Titanium Ti: 5 × (C% - 0.02) to 0.80 Molybdenum Mo: 2.50 ~ 3.50 ● Mechanical Properties: Tensile σb (MPa): ≥ 530 conditions yield strength σ0.2 (MPa): ≥ 205 Elongation δ5 (%): ≥ 40 Reduction of area ψ (%): ≥ 55 Hardness: ≤ 187HB; ≤ 90HRB; ≤ 200HV ● Heat treatment and microstructure specifications: Heat treatment specifications: 1) solid solution 1000 ~ 1100 ℃ rapid cooling; 2) According to the demand side, demand can be stabilized, heat treatment temperature of 850 ~ 930 ℃, but it must be specified in the contract. Microstructure: Organizing for the austenitic type. ● Delivery status: generally heat treatment delivery, the treatment types specified in the contract; not indicated, according to the heat treatment state of delivery.
