EN 10028-4 1.6228 Introduce
Normally all steel grades under EN 10028-4 1.6228 are normalized following a strict production process. During the normalizing process, the austenitic grain size of the material is improved, which is the main difference between this process and the tempering process. The material is then tempered so as to improve its welding properties, among other things.
Smelting temperature:1878°C - 1542°C
Application:Flat products made of steels for pressure purposes - Part 4: Nickel alloy steels with specified low temperature properties
