Because of its high rolling speed and precision,Sendzimir mill is favored high technology customers who are making very thin strip and difficult deformation silicon steel,stainless steel,The materials of Sendzimir rolls ar inclusive tool steel,die steel and high-speed steel.The rolls are manufactured under quenching and tempering processes of high temperature.
During the tempering process,secondary hardening is used to reach hardness of 55-60 HRC,60-63 HRC,61-64 HRC, 63-66 HRC etc,for different hardness requests.
