Press Breaking and Roll Forming
In both cases the equipment and tooling used for carbon steel can be used for stainless steel. However, there are several differences that need to be taken into account, viz.:
1. Due to its inherently higher strength and work hardening tendency, "springback" is much greater for stainless steel. Therefore, a greater degree of bending is required. This will depend on the grade of steel, its hardness, thickness, the bend radius and bend angle.
2. When running both carbon steel and stainless steel on the same equipment, it is advisable to plan operations carefully to avoid carbon steel "pick-up" on the stainless steel. It is recommended that the stainless steel be run before carbon steel or the equipment be thoroughly cleaned when changing from carbon steel to stainless steel. When changing from stainless steel to carbon steel, cleaning is not usually necessary. In cases where the equipment itself is old and worn and there is a danger of "pick-up" from this source, it is recommended that the working surfaces be covered with material such as PVC or PE.
3. Lubrication is not normally required, except in cases where galling and scoring occur. In such cases heavy duty emulsions can be used.
4. Prolonged working of stainless steel on equipment designed for carbon steel may lead to abnormal tool wear.
