DIN EN 10028-5 P355M 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 P355M and its guidelines can help to increase safety and performance, while reducing the production costs associated with pressure equipment.

Smelting temperature:1679°C - 1596°C

DIN EN 10028-5 P355M Material Machining Technology

Steel is one of the most widely used materials in the world. It can be found in an array of different projects ranging from bridges, cars, and aircrafts to everyday home appliances and equipment. One of the most widely used steel grades is DIN EN 10028-5 P355M, a high-strength, heat-treatable steel grade developed by the German Institute for Standardization (DIN). The availability of this type of steel has made it a popular choice in many applications. But due to its complex and unique characteristics, the machining of DIN EN 10028-5 P355M steel poses some noteworthy challenges.
