BS EN 10025-4:2019 pdf free download.,Hot rolled products of structural steels – Technical delivery conditions for thermomechanical rolled weldable fine grain structural steels.
BS EN 10025-4:2019 specifies technical delivery conditions for flat and long products of hot rolled weldable fine grain structural steels in the thermomechanical rolled condition in the grades and qualities given in Tables 1 to 3 (chemical composition) and Tables 4 to 6 (mechanical properties) in thickness ≤ 150 mm.
The steels specified in this document are especially intended for use in heavily loaded parts of welded structures such as, bridges, flood gates, storage tanks, water supply tanks, etc., for service at ambient and low temperatures.
