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.
Weathering steel plate refers to the low alloy structural steel with protective rust layer and atmospheric corrosion resistance, which can be used to manufacture steel structures such as vehicles, bridges, towers, containers, etc. Compared with ASTM A514 QT steel plate, ordinary carbon steel, weathering steel has better corrosion resistance in the atmosphere. Compared with stainless steel, weathering steel has only a small amount of alloy elements, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium and so on. The total amount of alloy elements only accounts for a few percent, instead of more than 10 percent as stainless steel, so the weathering steel price is relatively low.
Alloy elements have the most significant strengthening effect on steel in quenched and tempered state. The primary purpose of adding alloying elements to steel is to improve the hardenability of steel and to ensure that martensite is easily obtained during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are finer, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, ASTM A514 QT steel plate.
Hot Rolled Plates ASTM A514 QT steel plate Machining After final forging/forming and Heat treatment process, all the pipe Fittings, Flanges, Fasteners, Etc. are sent for machining i.e. and preparation, O/D and I/D matching as per dimensional codes. An Expert Q.C. engineer is involved and he keeps constant vigil on every machining operation. Step machining is carried out as required by the codes. GO and NO-GO gauges are used to check the O/D & I/D of the fittings, Flanges, etc.
We are experienced shipbuilding and marine grade steel materials supplier and exporter with more than 20 years experience. For any question about the ASTM A514 QT steel plate shipbuilding steel materials, such as shipbuilding steel price, ABS EH36 steel specification, Lloyds grade A steel properties, AH36 steel mechanical properties, AH32 steel price, DH32 steel dimensions, difference between EH36 and DH 36 etc., please feel free to consult us.
We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards. The most important thing is that we have set up the correct concept of after-sales service, "customer first, sincere service for users".
