15Mo3 steel plate executive standard: DIN 1715515Mo3 steel plate classification: Boiler and pressure vessel steel plateApplication of 15Mo3 steel plate: 15Mo3 steel plate is mainly used to manufacture spherical storage tanks with a capacity of more than 50m3, as well as class II and III vessels such as single-layer roll welding vessels, multi-layer heat sleeve roll welding vessels, ASTM A709 carbon steel plate multi-layer binding vessels and low-temperature pressure vessels.
The ASTM A709 carbon steel plate processing performance is good. Due to the uniform control of steel plate performance, excellent performance coordination and good toughness guarantee, the steel plate bending processing, drilling, cutting and other mechanical processing properties are excellent. In addition, the surface of the ASTM A709 carbon steel plate steel plate is smooth and beautiful by inhibiting and removing oxide scale from slab heating to rolling process and heat treatment in furnace without oxidation atmosphere.
Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the ASTM A709 carbon steel plate steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This ASTM A709 carbon steel plate method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.
