DIN EN 10028-5 1.8833 Introduce
DIN EN 10028-5 is an European standard for hot-rolled flat products made of steels for pressure purposes. It applies to steels for pressure purposes with specified elevated temperature properties. These steel grades are also classified according to their chemical composition and mechanical properties. The mechanical properties of these steels are guaranteed by a range of tests specified in the standard. This type of steel is used in pressure vessels, boilers, steam lines, and steam turbines. The use of DIN EN 10028-5 1.8833 and its guidelines can help to increase safety and performance, while reducing the production costs associated with pressure equipment.
Smelting temperature:1876°C - 1644°C
