EN 10028-4 12Ni19 Introduce
The EN 10028-4 standard is an important steel standard introduced to the European market to provide standardised steel across different European countries. This standard covers steel flat products, long products and coated products in order to ensure the quality and properties of the steel produced. The various tests and inspections laid out within the standard are needed to ensure that the steel produced meets the required specifications according to the standard.
Smelting temperature:1374°C - 1862°C
Application:Flat products made of steels for pressure purposes - Part 4: Nickel alloy steels with specified low temperature properties
