Product Description Factory Price and Top Quality 5120 20Cr4 JIS G4053 SCR420 Low Carbon Steel Alloy Structural Steel steel round bar Machinery Part Steel Tempering And Quenching Characteristics and scope of applicationStrength and hardening of high performance, after quenching and low-temperature tempering, can get good comprehensive mechanical properties and low-temperature impact toughness, no temper brittleness and should, therefore, be of secondary quenching to improve toughness in the center, unfavorable cooling quenching, cold deformation plastic high, cold drawing, the high temperature normalizing and tempering, good processability, good weldability. Welding should generally be preheated to 100 to 150 DEG C and is generally regarded as penetration of carbon steel Heat treatment and metallurgical structure:Specification of heat treatment: hardening 880oC for the first time, 780~820oC, water cooling, oil cooling; tempering 200oC water cooling, air cooling.1.International StandardGBAISIJIS20CrS120SCr4202.Chemical Composition(Wt%) :3.Available Size(mm) :MnSPCrNiCu0.60-0.90Max 0.030Max 0.0300.90-1.20Max 0.25Max 0.030 Flat Bar Size(mm)Round bar Size(mm)ThicknessWidthLengthDiameterLength10-700155-22002000-600020-2003000-5504.Product Process:Electric-Furnace Smelting(EF)→Ladle Furnace(LF)→Vacuum Degassing(VD)→ Argon protected ingot →Multidirectional Forging → (Concave forging →)Normalizing+Hydrogen Diffusion Annealing → Ultrasonic Flaw Detection →Queching+Tempering Prehardened 5.
