Werkstoff Standards


Werkstoff Steel stockholders and suppliers, delivering to the whole of the UK. Werkstoff steel grades are used widely in engineering and industry. Each specification is made up of five digits, the first digit is followed by a decimal point then four digits follow thereafter. This system was designed to be compatible with computerisation, but there is little information within each grade to help understand the make up of the steel. Werkstoff Numbers were developed and introduced by the “Deutsches Institut für Normung” (German Institute for Standardisation) a no-profit organization responsible for DIN standards.
