HII boiler and pressure vessel steel Description

HII boiler and pressure vessel steel, also named heat-resistant steel, DIN 17155 HII pressure vessel steel is mainly used for the manufacture of hot-rolled steel plates for steam boiler equipment, pressure vessels, large pressure pipes and similar components. HII steel plate implements the DIN 17155 standard. The digital grade is 1.0425. It is mainly used for the manufacture of spherical storage tanks with a size of more than 50 cubic meters. It is widely used in petroleum, chemical, power stations, boilers and other industries. Equipment and components such as boilers, spherical tanks, oil and gas tanks, liquefied gas tanks, boiler drums, liquefied petroleum gas cylinders, high-pressure water pipes of hydropower stations, turbine volutes, etc.

DIN 17155 HII boiler and pressure vessel steel can still show characteristics at higher temperature, local temperature can reach 600C, and can still show characteristics under long-term load conditions. DIN 17155 HII boiler steel not only guarantees normal temperature performance, but also guarantees mechanical properties at higher temperatures, and is suitable for steam boiler equipment, pressure vessels with higher working temperatures and similar structural parts. HII is delivered in a normalized state. As one of the main suppliers of HII pressure vessel steel in China, BBN Steel can provide HII pressure vessel steel plates of various sizes, and provide cutting and deep processing services according to customer needs to meet customer requirements.
