EN 10028-3 275 NL 2 steel,EN 10028-3 275 NL 2 steel Specification
EN 10028-3 275 NL 2 steel is a weldable fine-grain steel suitable for the fabrication of pressure vessels for pressurised gases and chemicals, industrial boilers, compressors and heat exchangers. EN 10028-3 275 NL 2 steel is intended for use in moderate to high temperature service.
EN 10028-3 275 NL 2 steel characteristic:
1.EN 10028-3 275 NL 2 steel has good strength, it can be made of boilers and components to withstand a certain long-term high temperature stress;
2.EN 10028-3 275 NL 2 steel has good toughness and low effectiveness of the tendency in the use of bending, curling, deformation processing such as cold, after more prolonged storage and use remains a good toughness;
3.EN 10028-3 275 NL 2 steel has good weldability and resistance to intergranular corrosion. For the manufacture of boiler drum, beams and wall panels.
EN 10028-3 275 NL 2 steel Specification:
Thickness: 8mm-300mm
width: 1500mm-4020mm
Length: 3000mm-18000mm
PS: EN 10028-3 275 NL 2 steel plate maximum weight can not beyond 25 tons.
According to the above EN 10028-3 275 NL 2 steel characteristics and needs of users, EN 10028-3 275 NL 2 steel has hot rolled, controlled rolling, normalizing, annealing, tempering, normalizing + tempering, tempering delivery states.
