Detailed Product Description: | Standard: GB / T 3077-1999 [Main features] This is a quenched and tempered carbon manganese steel, steel strength, ductility and wear resistance are high, cutting and heat treatment process can have good performance in the critical oil quenching diameter of 8.5 ~ 23mm, the critical quenching in water through diameter of 20 ~ 42mm; but there temper brittleness and thermal sensitivity, and easy to crack when quenched. The sensitivity of steel with white spots, cold plastic deformation is not high, poor welding, require preheating to 100 ~ 425 ℃ before welding. [Application Examples] Generally used in the quenched state, can be used to manufacture heavy-duty work under the conditions of parts such as shafts, crankshafts, axles, piston rod, worm, lever, rod, a load of bolts, screws, reinforcement rings, springs, and other transfer quality pieces. Generally used for small cross-section diameter less than 50mm important parts, this steel static strength and fatigue properties of 40Cr steel and are very, it can be used for the generation of 40Cr steel. [] Chemical composition (mass fraction) (%) Carbon C: 0.35 ~ 0.45 Si Si: 0.20 ~ 0.40 Manganese Mn: 1.60 ~ 1.80 P P: "0.030 (residual content) Sulfur S: "0.030 (residual content) Chromium Cr: ≤ 0.309 (residual content) Ni-Ni: ≤ 0.30 (residual content) Copper Cu: ≤ 0.25 (residual content) [Mechanical properties] Blank sample size (mm): 25 Heat treatment: The first quenching temperature (℃): 840; coolant: water, oil Second quenching temperature (℃): - Tempering heating temperature (℃): 540; coolant: water Tensile strength (σb / MPa): ≧ 885 Yield point (σs / MPa): ≧ 735 Elongation (δ5 /%): ≧ 12 Reduction of (ψ /%): ≧ 45 Impact absorbed energy (Aku2 / J): ≧ 55 Brinell hardness (HBS100/3000) (annealing or tempering condition): ≦ 217 Sample size: Sample size is 25mm rough 40Mn2 steel bar 40Mn2 steel |
