Detailed Product Description: | 20CrNiMo for containing molybdenum in addition to good overall performance capability is also a certain temperature outside. For the manufacture of turbine engine rotor gear the whole cross-section forgings, rod valve. Chemical composition: Mass fraction (%): Carbon C: 0.17 ~ 0.23 Si Si: 0.17 ~ 0.37 Manganese Mn: 0.60 ~ 0.95 Sulfur S: to allow the residual content of ≤ 0.035 Phosphorus P: allow the residual content ≤ 0.035 Chromium Cr: 0.40 ~ 0.70 Ni-Ni: 0.35 ~ 0.75 Copper Cu: to allow the residual content of ≤ 0.30 Mo Mo: 0.20 ~ 0.30 Mechanical properties: Sample size [blank] 15mm [Heat] Quenching temperature (℃): 850; Coolant: Oil Tempering heating temperature (℃): 200; coolant: air [Mechanical properties] Tensile strength σb (MPa): ≥ 980 (100) Yield strength σs (MPa): ≥ 785 (80) Elongation δ5 (%): ≥ 9 Reduction of area ψ (%): ≥ 40 Impact energy Akv (J): ≥ 47 Impact toughness αkv (J/cm2): ≥ 59 (6) Brinell hardness (HBS100/3000) (annealing or tempering condition): ≦ 197 Delivery status: to heat treatment (normalizing, annealing, or tempering) or heat treatment delivery, delivery status should be indicated in the contract. Key Features: 20CrNiMo formerly U.S. Steel AISI, SAE standard steel No. 8720. Steel Hardenability performance 20CrNi similar. Although the Ni content 20CrNi steel steel half, but a small amount of Mo elements, the isothermal transformation of austenite to the right upper part of the curve; because of an appropriate increase in Mn content, resulting in the hardenability of this steel is still very good, strength than 20CrNi steel. Commonly used in the manufacture of small cars, tractor engine and transmission in gear; can replace the 12CrNi3 steel high performance requirements of the Department of carburizing heart pieces, pieces of cyanide, such as oil drilling and open pit metallurgical roller bits used claws and teeth cone body. 20CrNiMo for containing molybdenum in addition to good overall performance capability is also a certain temperature outside. For the manufacture of turbine engine rotor gear the whole cross-section forgings, rod valve. Application examples: Commonly used in the manufacture of small cars, tractor engine and transmission in gear, but also can replace 12CrNi3 steel high performance requirements of the Department of carburizing heart pieces, pieces of cyanide, such as oil drilling and metallurgical pit with teeth and claws cone body. 20CrNiMo steel bar 20CrNiMo steel |
