S355 Carbon steel plate is a carbon steel used in buildings, bridges, ships, vehicles and other structures, which must have a certain strength and require impact performance and welding performance when necessary.
AH36 steel plate is a steel plate with a thickness of no more than 150 mm for the manufacture of ocean going, coastal and inland navigation ships, fishing boats and offshore engineering structures. For steel plates with Z-direction requirements, add Z25 and Z35 to the suffix, which is used as structural steel for high-strength ships and offshore engineering.
S275JR steel plate is generally used for drilling machines, shovels, electric wheel dumpers, excavators, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment and other structural parts used in construction and various projects.
ST12 is German standard (DIN1623), It's ordinary cold rolled steel. In principle, ST12 can only be bent and formed, and no stamping is allowed.
SPCC carbon steel plate is generally used in the production of steel structures, vehicles, ships and bridges, and has good corrosion resistance and atmospheric corrosion resistance.
SA516Gr. 70 is widely used in petroleum, chemical industry, power station, boiler and other industries to make reactors, heat exchangers, separators, spherical tanks, gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum gas cylinders, high-pressure water pipes of hydropower stations, water turbine shells and other equipment and components.
The 4130 carbon steel plate is usually used in the quenched and tempered state. When the carbon content is at the lower limit, the steel can also be used as the carburized steel with higher central strength.
201 stainless steel is mainly used for decorative tubes, industrial tubes and some shallow stretched products. Such as: oil waste gas combustion pipeline; Engine exhaust pipe; Boiler shell, heat exchanger and heating furnace components; Silencing parts for diesel engine; Boiler pressure vessel; Chemical transport vehicle; Expansion joint; Spiral welded pipe for gas furnace pipe and dryer, etc.
Use of 2205 stainless steel plate:
1. The heater is generally used in the oil refining unit;
2. Chemical plant equipment pipeline;
3. Fast cooling cylinder for solid solution used in textile industry;
4. Seamless steel pipe for heat exchanger and condenser.
5. High pressure seamless steel pipe for food (gb-2000) is a high-quality carbon structural steel and alloy steel seamless steel pipe suitable for chemical equipment and pipes with working temperature of - 40~400 ° C and working pressure of 10~30ma.
6. Seamless steel pipes for geological drilling and oil drilling control.
7. Cracking pipe for petrochemical industry is used to transport high-temperature and high-pressure fluid on fertilizer equipment.
904L stainless steel plate (super austenitic stainless steel) is a high alloyed austenitic stainless steel with very low carbon content. It has good corrosion resistance in dilute sulfuric acid and is specially designed for environments with severe corrosion conditions. It has high chromium content and sufficient nickel content. The addition of copper makes it have strong acid resistance, especially high resistance to chloride interstitial corrosion and stress corrosion cracking. It is not easy to appear corrosion spots and cracks. Its pitting resistance is slightly better than that of other steels. It has good processability and weldability, and can be used for pressure vessels.
