Where the heat treatment of p355gh is used

Pageviews:

Among stainless steels, austenitic stainless steel has the best process performance. Due to its good plasticity, heat treatment of P355GH, austenitic stainless steel can be processed into various plates, tubes and other profiles, suitable for pressure processing. Martensitic stainless steel has poor process performance due to its high hardness. Stainless steel has corrosion resistance, enhanced strength, steel deformation is not easy to crack and environmental protection performance, not easy to rust, and has good ductility and toughness. Stainless steel is suitable for use in harsh environments (indoor and outdoor environments such as humidity, acid and alkali).

After extrusion, the heat treatment of p355gh tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.

During the welding of hardfacing wear-resistant steel plate, heat treatment of p355gh, the welding shall be carried out in strict accordance with the drawing, welding process and relevant standards. Follow the welding sequence of first welding the base layer, then welding the transition layer, and then welding the multiple layer. In order to prevent adhesion of welding spatter, anti spatter coating should be applied within 100 mm on both sides of groove of stainless steel clad plate before welding.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
