Forged steel work roll performs as a tool to transform materials under normal room temperature, therefore , it is the most wear and tear spare parts during the rolling process . With 2%Cr, 3%Cr, 5%Cr material series , we have greatly improved our products both in terms of quality and diversification .
Currently , our product is widely used in a variety of applications , such as anti hydrogen-attack roll, ultra-deep hardened roll, anti-roll mark roll, anti-roll accident roll and the high wear resistance roll and so on.

Sendzimir mill is favored by high technology customers because of high rolling precision , such as very thin strip and difficult deformation silicon steel, stainless steel.
The material of Sendzimir work roll is tool steel, die steel and high-speed steel. These are materials of high hardness . The rolls are manufactured under quenching and tempering processes of high temperature . During the tempering process, secondary hardening is used to reach hardness of 60-63HRC, 61-64 HRC, 63-66HRC etc, for different work rolls .
High hardness tool steel and die steel are used as raw materials for Sendzimir intermediate roll. The rolls are also manufactured under quenching and tempering process of high temperature. During tempering process, secondary hardening is used to reach hardness of 55-60HRC for different intermediate rolls.
Name | Type of material | Hardness |
Sendzimir work roll | tool steel, die steel and high-speed steel | 60-66HRC |
Sendzimir intermediate roll | tool steel, die steel and high-speed steel | 55-60HRC |
Available in diameters of 6" to 36" and up, we also design and manufacture custom wheels for your specific design application in any configuration. And our sales engineers are always ready to make recommendations when these wheels need to be integrated into complete wheel assemblies on time and when you need it.
Our large inventory of carbon and alloy steel materials, coupled with our in-house rough and finish machining capabilities (up to 40" in diameter), makes rush delivery and breakdown situations our specialty. British India Engineering Corporation is dedicated to keeping your business moving and getting you back on-line because lost time is lost money.
If you dont have a written specification or drawing, Irwin has the ability to reverse engineer your part and produce it to original specifications to get you back on-line quickly and cost effectively.
