Chrome plating - Import export

STEEL GRADES The standrard stock of chromed bars consists of steel grades C45 or C45E or C45R and 20MnV6 in untreated delivery condition (+AR) and 42CrMo4 in quenched and temperd delivery condition (+QT). DELIVERY CONDITIONS The solid bars subjected to chroming process are available in different delivery conditions in orde to obtain specific properties. NORMALIZATION Heat treatment consisting heating process followed by gradual cooling in controlled atmosphere. Thanks to this process the steel structure becomes more "refined" and improve its impact properties (perlitic structure). INDUCTION HARDENING The surface of the steel bar is heated by electric induction followed by fast cooling. This process leads to a high surface hardness but also to fragility and low impact values (Martensite surface structure). QUENCHING AND TEMPERING Quenching process followed by tempering. This process leads to a good hardness and resistance and it reduces its fragility in comparsion to induction...
