DIN 17155 HI is a standard specification for boiler and pressure vessel steel sheets. It specifies the requirements for carbon steel sheets intended for use in elevated-temperature service.
The HI designation indicates that the steel sheet has a minimum yield strength of 235 MPa (megapascals) and is suitable for applications involving moderate temperatures and pressures.
These sheets are primarily used in the construction of boilers, pressure vessels, and storage tanks that handle high-temperature fluids or gases. They offer good weldability and formability, allowing for ease of fabrication and installation.
DIN 17155 HI boiler pressure vessel steel sheets demonstrate excellent resistance to high-temperature environments and provide reliable structural integrity under demanding conditions. The sheets are manufactured through various processes, including hot rolling, to achieve the desired thickness and mechanical properties.
By meeting the DIN 17155 standard, these steel sheets ensure the safety and reliability of pressure equipment, making them suitable for use in industries such as petrochemical, power generation, and process engineering.
