What is the A573 Grade 70 for construction of storage tanks tensile strength

Our company was founded in 2000, which initially committed to providing high-quality steel A573 Grade 70 for construction of storage tanks products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export A573 Grade 70 for construction of storage tanks steel to the international market, opening up the international steel market.

SPV355 steel is a kind of Japanese standard steel for medium temperature pressure vessels. The executive technical standard of SPV355 steel is JIS G3115. SPV355 steel is widely used in petroleum, chemical industry, power station, boiler and other industries. SPV355 steel is used to make reactor, A573 Grade 70 for construction of storage tanks heat exchanger, separator, spherical tank, oil and gas tank, liquefied gas tank, nuclear reactor pressure shell, boiler drum, liquefied petroleum cylinder, high-pressure water pipe of hydropower station, turbine volute and other equipment and components.

Heat treatment advantages of A573 Grade 70 for construction of storage tanks, SA516 Gr 70 pressure vessel steel:
1) SA516 Gr 70 pressure vessel steel quenching: The hardness of SA516 Gr 70 pressure vessel steel is increased, but the toughness is decreased.
2) SA516 Gr 70 pressure vessel steel normalizing: Improve strength and toughness.
3) SA516 Gr 70 pressure vessel steel annealing: Eliminate quenching effect, eliminate stress, uniform composition.
4) SA516 Gr 70 pressure vessel steel tempering: Uniform composition, slightly reduce hardness, greatly improve toughness.

After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the A573 Grade 70 for construction of storage tanks plate should be derusted before cutting.

Hot Rolled Plates A573 Grade 70 for construction of storage tanks 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.

Over the years, the company has maintained long-term stable business relationships with major domestic steel mills and foreign steel companies. The company's main boiler and pressure vessel steel plates, low alloy high-strength steel plates, wear-resistant steel plates, corrosion-resistant steel plates, A573 Grade 70 for construction of storage tanks bridge steel plates , strucural teel plates, steel plates for alloy structures, mold steel plates, steel plates for shipbuilding and production platforms, composite steel plates, steel plates for oil and gas pipelines.
