High Chromium Iron Roll II for Tempered Work Rolls is a roll made of high chromium iron that has been subjected to a tempering process. It can improve the organizational structure of the roll, and improve its toughness and impact resistance so that it can withstand greater impact loads and is less likely to break. High chromium iron has good thermal fatigue resistance, can withstand impact and vibration under high temperature and high pressure, and is not prone to thermal cracks and breakage. Quenching and tempering treatment can further improve the thermal fatigue resistance of the roll, making it suitable for high-strength and high-precision rolling operations. Quenching and tempering treatment can eliminate the residual stress of the roll, improve its dimensional stability, make it less likely to deform and ensure the accuracy and quality of rolled products. High chromium iron rolls II for tempered work rolls are also used as finishing work rolls in finishing mills for rolling high-precision steels. High chromium iron rollers II for tempered work rolls are used for rolling stainless steel, heat-resistant steel, and other special steels. High chromium iron roller II used for quenching and tempering work rollers has good impact resistance, and its impact value is generally akv ≥ 15 J/cm2. Higher dimensional accuracy ensures the quality of rolled products.
