SAE4340, same as UNS G43400. Tensile strength σb ≥980(100) Yield strength σs ≥835(85), used to manufacture important parts with high strength and good plasticity. After nitriding treatment, make important parts with special functional requirements, such as shafts, gears, and gears. Firmware etc. Delivery A573 grade 70 plate in heat treatment (normalizing, annealing or high temperature tempering) or without heat treatment.
NM400 alloy steel plate is a kind of wear-resistant steel plate. NM—The first letter of the Chinese pinyin 400 of the characters “resistant” and “grind” for wear resistance is the HB value of the Brinell hardness value. NM400 alloy plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other product parts. Excavator, loader, bulldozer bucket plate, blade, side blade, blade.
Its weatherability is the protection of the oxide layer of weatherproof steel. The mechanism of corrosion resistance of weathering steel is mainly based on the analysis of long-term exposed rust layer. Generally speaking, it is believed that weathering steel can form a dense layer of weathering rust through long-term exposure, which has a good protective effect on weathering steel, A573 grade 70 plate.
Chemical composition of 42CrMo seamless steel pipe: C: 0.38-0.45, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.90-1.20, Mo: 0.15-0.25, V: 0.15-0.30. Mechanical properties of 42CrMo seamless steel pipe: tensile strength: 1080 MPa, yield strength: 930 MPa, elongation after fracture: 12%, reduction of area: 45%, impact energy: 63J. Due to the effect of carbon and chromium content, A573 grade 70 plate, 42CrMo seamless steel pipe has better strength and hardenability, higher fatigue strength and resistance to multiple impact after quenching and tempering, good impact toughness at low temperature and no obvious temper brittleness. It is generally used after quenching and tempering.
The boiler steel plates are among our main products. Other than standard size boiler steel plates, we also provide A573 grade 70 plate cutting, bending and so on processing to change plate size and shape according to your requirements. Welcome to consult us about A573 grade 70 plate ASTM A204 grade B properties, SA 516 gr 70 temperature range, ASTM A285 grade C chemical composition, boiler steel price and so on questions and ask for offer.
