EN 10028-6 1.8888 Introduce
The EN 10028-6 steel standard is a European harmonised standard that provides requirements for hot-rolled flat steel products for pressure vessels. This standard sets chemical and mechanical property requirements, production control requirements, notch toughness, testing requirements and acceptance criteria. The purpose of the standard is to maintain a consistent product quality which makes it easier for organisations to buy, sell and manufacture steels.
Smelting temperature:1731°C - 1393°C
Application:Pressure flat steel products - Part 6: Weldable fine grain steel, quenched and tempered
