Product Description
High Cr Steel Roll(HCrS)
High Cr Steel Roll is known for having lower carbon content that make it an idealized product range in current industry. Basically, the available range is designed to be used in roughing stands and hot strip mills. A special process of heat treatment is done for making this range strong enough to be used for different applications. High spinning of High Cr Steel Roll increases the speed that specifically creates a centrifugal force so as to push the molten metal into mold.
Key features:
- Good hardness
- Maximum tensile strength
- Superior finish
