Mechanical Properties of S490 Alloy Steel
Tensile strength σb (MPa): ≥930 Yield strength σs (MPa): ≥735 Elongation δ5 (%): ≥10 Area reduction ψ (%): ≥45 Impact energy Akv (J): ≥47 Brinell Hardness (HBS100/3000) (annealed or high-temperature tempering state): ≦187 Sample size: The sample blank size is 15mm
Application Scope of S490 Alloy Steel
SS490 is carburized steel with good performance and high hardenability. After carburizing and quenching, it has a hard and wear-resistant surface and a tough core. It has high low-temperature impact toughness, medium weldability, and can be cut after normalizing. Good sex. SS490 Lost Wax Investment Castings are widely used as carburized parts with small cross-sections and high-load tempered parts with large cross-sections, such as gears, shafts, spindles, worms, sleeves of speed regulators, friction wheels of transmission devices, etc., and also can replace 20CrNi steel to make parts with small cross-section size, medium pressure, and no large impact load.
Heat Treatment Specifications and Metallographic Structure of S490 Alloy Steel
Quenching heating temperature (℃): 850℃, oil cooling; Tempering heating temperature (℃): 200℃, water cooling, air cooling; Metallographic structure: tempered martensite. Delivery status: Delivery in heat treatment (normalizing, annealing, or high-temperature tempering) or non-heat treatment status, the delivery status should be specified in the contract.
