Detailed Product Description: | 30CrMnSiA Material: alloy structural steel Grade: 30CrMnSiA Standard: GB / T 3077-1988 Characteristics of the application: 30CrMnSiA the case of carbon quenched and tempered steel, high strength, poor welding performance. 30CrMnSiA tone quality, high strength and toughness, hardenability or. After quenching the material to do the wheel shafts, gears, sprockets. 30CrMnSiA has good workability, processing deformation tiny, anti-fatigue performance is very good. For shafts, piston type spare parts. For cars, planes, a variety of special wear-resistant parts. ● chemical composition: Carbon C: 0.28 ~ 0.34 Silicon Si: 0.90 ~ 1.20 Mn Mn: 0.80 ~ 1.10 Sulfur S: Allow the residual content of ≤ 0.025 Phosphorus P: Allow the residual content of ≤ 0.025 Chromium Cr: 0.80 ~ 1.10 Ni: to allow the residual content of ≤ 0.030 Cu: to allow the residual content of ≤ 0.025 ● Mechanical Properties: Tensile strength σb (MPa): ≥ 1080 (110) Yield strength σs (MPa): ≥ 835 (85) The elongation δ5 (%): ≥ 10 Reduction of area ψ (%): ≥ 45 Impact energy Akv (J): ≥ 39 Impact the toughness the value αkv (J / cm 2): ≥ 49 (5) Hardness: ≤ 229HB Sample size: the sample blank size of 25mm ● Heat treatment and microstructure: Standardized heat treatment: hardening 880 ° C, cold oil; tempering 540 ° C, water-cooled, oil cooled. Delivery status: heat treatment (normalizing, annealing, or high-temperature tempering) with or without heat treatment delivery, the delivery status should be indicated in the contract. High strength, but in the case of carbon quenched and tempered steel, have greater hardenability, welding performance is poor. High strength and toughness of the material after quenching and tempering, hardenability or. After quenching the material to do the wheel shafts, gears, sprockets. If you do the cutting tool, roughing tool shape. Quenching and tempering. Carbide milling cutter blade, polishing machine polishing. Surface roughness of 3.2 should be no problem. Gray, the color of the material galvanized not just to a beautiful, can also be anti-rust |
