Customers are welcome to visit our company at any time. We are always ready to support you.

ASTM A516 is also known as ASME SA516. The A516 / SA516 standard specification for pressure vessel plates, carbon steel, for moderate- and lower-temperature service. A grade a516 grade 70 bar intended primarily for service in welded pressure vessels where improved notch toughness is required, and is normally found in moderate and lower temperature applications. All plates over 1-1/2″ Thick are required to be normalized. A516 Grade 70 steel is the most popular pressure vessel grade of steel plate in the industry.

The cold rolled sheet does not produce scale because it is rolled at room temperature. Therefore, the surface quality of cold plate is good and the dimension precision is high. In addition, the mechanical and technological properties of cold rolled coil are better than that of hot-rolled steel sheet. In many fields, especially in the field of home appliance manufacturing, it has gradually replaced hot-rolled steel sheet, a516 grade 70 bar.

Fake and inferior steel plates are easy to scratch because of the simple equipment of the manufacturers of fake and inferior materials, which are easy to produce burrs and scratch the surface of the steel plate. Deep scratches reduce the strength of the a516 grade 70 bar, steel plate. The surface of the fake and inferior material is prone to cracks, because its billet is adobe, which has many pores. The adobe is subjected to thermal stress during the cooling process, and cracks are generated, and there will be cracks after rolling.

10# seamless steel pipe chemical composition : C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. 10# seamless steel pipe mechanical properties: recommended heat treatment temperature: 930℃, tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%, impact energy is not required. a516 grade 70 bar, 10# seamless steel pipe has high plasticity and toughness, no temper brittleness tendency, and good weldability. Its machinability under cold drawing or normalizing treatment is obviously improved. In cold state, 10# seamless steel pipe is easy to be extruded and molded, but its strength is low, and its hardenability is very poor.
