In recent years, in line with the development trend of iron and A514 grade J alloy steel plate steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which A514 grade J alloy steel plate are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
EN10025-3 S460NL material is a hot rolled low carbon manganese steel. It has min. 460Mpa yield strength and low temperature impacting at -50℃ with minimum energy 27 J. A514 grade J alloy steel plate, S460NL also has good weldable property and possess good impact resistance (also in sub-zero temperatures). We supply S460NL steel plate for deep oceans, bulit the tanks or structural parts of nuclear submarine all over the world. Large stock of S460NL hot rolled plate available in India, Bangladesh, Malaysia, Nigeria, South Africa & UAE.
Special boiler steel is derived from carbon structural steel, A514 grade J alloy steel plate. The expression of boiler steel grade is similar to that of high-quality carbon structural steel, and the carbon content is usually 0.20%. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same brand, but the mechanical properties are strictly required, especially the impact toughness, and the aging sensitivity is required to be small. After deoxidation and removal of non-metallic inclusions, boiler steel has a uniform structure, the grain size is controlled at 3-7 grade, and the defects such as interlayer, shrinkage, porosity and porosity are relatively less.
The purpose of A514 grade J alloy steel plate quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of A514 grade J alloy steel plate. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.
ASTM A588 is a high strength low alloy HSLA steel (high strength, low alloy) containing a small amount of alloying elements copper, chromium and AMP. Nickel. These alloying elements effectively improve the properties of a588 and expand its application range. Firstly, the alloy composition increases the A514 grade J alloy steel plate yield point strength to 50 Ksi and the tensile strength to 70 Ksi. Secondly, a588 A514 grade J alloy steel plate has high copper content, atmospheric corrosion resistance and long working time. Because of its excellent comprehensive performance, a588 angle steel is widely used in bridge, building and other structural fields.
