DIN pressure vessel steel material 17Mn4 boiler steel plate delivery status: hot rolled, controlled rolled or normalized / AR, Cr or N. 17Mn4 boiler steel plates are normally delivered as normalized. According to the negotiation between the 17Mn4 boiler steel plate supplier and the demander, normalizing rolling can be used instead of normalizing.
