3Cr13 stainless steel
Stainless Steel: 3Cr13
Standard: GB / T 1220-1992
● Features and application:
Martensitic stainless steel grades are used 1Cr13, 3Cr13, etc., due to the higher carbon content, it has a high strength, hardness and wear resistance, corrosion resistance, but somewhat less for higher mechanical properties, corrosion resistance Some parts on the general requirements, such as springs, turbine blades for cutting tools, nozzles, valve seats, valve / hydraulic valve. Such steel is quenched, tempered after use.
● Chemical Composition:
Carbon C: 0.26 ~ 0.35 Si Si: ≤ 1.00
Manganese Mn: ≤ 1.00
Sulfur S: ≤ 0.030
Phosphorus P: ≤ 0.035
Chromium Cr: 12.00 ~ 14.00
Ni: to allow containing ≤ 0.60
● Mechanical Properties:
Tensile strength σb (MPa): quenching and tempering, ≥ 735
Conditions yield strength σ0.2 (MPa): quenching and tempering, ≥ 540
Elongation δ5 (%): quenching and tempering, ≥ 12
Reduction of area ψ (%): quenching and tempering, ≥ 40
Impact energy Akv (J): quenching and tempering, ≥ 24
Hardness: Annealed, ≤ 235HB; quenching and tempering, ≥ 217HB
● Heat treatment and microstructure specifications:
Heat treatment specifications: 1) annealing, 800 ~ 900 ℃ slow cooling or rapid cooling of about 750 ℃??; 2) quenching, 920 ~ 980 ℃ oil cooling; 3) temper, 600 ~ 750 ℃ ??fast-cooling.
Microstructure: Organizing for the martensitic type.
