S420N steel

EN 10111 S420N steel plate/sheet,EN 10111 S420N steel plate/sheet, under EN standard, we can regardS420N steel plate/sheet as fine-grain structural steels, normalised rolled steels.EN 10111 S420N is mainly used as ine-grain structural steels, normalised rolled steels.

EN 10111 S420N steel plate/sheet is a hot rolled structural steels,which shall be done low temperature charpy_V impacting test under EN10025 standard,the temperature shall be minus 20 centi degree,and the impacting energy shall be min 27J.
