Boiler plate DIN HI pressure vessel steel

DIN HI is a German standard for boiler plate pressure vessel steel. It is also known by its material number 1.0345.

DIN HI is classified as a non-alloy quality steel and is primarily used in the manufacturing of boilers, pressure vessels, and heat exchangers. It has good weldability and high resistance to pressure at elevated temperatures, making it suitable for applications involving steam and gas pressure.

The material composition of DIN HI typically includes carbon (C), manganese (Mn), silicon (Si), phosphorus (P), sulfur (S), and trace amounts of other elements. The exact composition may vary according to the specific manufacturer and production process.

With a minimum yield strength of 185 MPa, DIN HI offers adequate strength for withstanding the internal pressures experienced in boiler and pressure vessel applications.

It is important to note that when selecting materials for boiler or pressure vessel construction, it is essential to adhere to the relevant standards and codes, such as EN and ASME, to ensure compliance with safety regulations and quality requirements.
