EN 10028-6 1.8866 Introduce

EN 10028-6 steel standard is a European standard which recognizes hot-rolled flat steel products for pressure vessel applications. Steel products in this family include a variety of plate products that are designated as either normalised rolled, thermomechanically rolled, thermomechanical control processed (TMCP) or fine grain steels. The purpose of EN 10028-6 and other European standards is to ensure a consistent product quality, while also providing adequate information that product purchasers may use to make informed decisions.

Smelting temperature:1421°C - 1673°C
