The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, NV A36 dry cargo ship steel seamless steel pipes for ships and petroleum cracking NV A36 dry cargo ship steel steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many NV A36 dry cargo ship steel products have been exported to the Middle East, India, Southeast Asia and Europe and America.
SPV355 grade is a kind of steel for medium temperature pressure vessel of Japanese standard. The technical standard is JISG3115. It is widely used in petroleum, chemical, power station, boiler and other industries to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, equipment and components such as liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum gas cylinders, high-pressure water pipes of hydropower stations, and turbine volutes.
Strip steel is a kind of steel plate with thin thickness, narrow width and long length. Strip steel can be made of common carbon steel, carbon structural steel, spring steel, tool steel, stainless steel, etc. Strip steel has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. There are many kinds of strip steel, NV A36 dry cargo ship steel. Hot rolled steel strip is mainly used for cold-rolled billets, cold-formed steel billets, welded steel pipe billets, manufacture of bicycles and small hardware products.
The microstructure of the quenched and tempered alloy steel, NV A36 dry cargo ship steel after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.
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 NV A36 dry cargo ship steel yield point strength to 50 Ksi and the tensile strength to 70 Ksi. Secondly, a588 NV A36 dry cargo ship steel 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.
