441 Stainless Steel Cold Rolled Strip 0.1-200mm Thickness

China factory 441 Cold Rolled stainless steel strip

In the process of cold rolling, since no heating is carried out, it is rolled at room temperature and no scale is produced. Therefore, cold-rolled stainless steel strip has good surface quality and high dimensional accuracy. Coupled with annealing treatment, its mechanical properties and process properties are better than those of hot rolling. Thin steel strip, in many fields, the performance and structure of the product can meet some special requirements, such as electromagnetic performance, deep drawing performance, etc., especially in the field of home appliance manufacturing, it has gradually replaced hot-rolled thin steel strip.

In general, cold-rolled stainless steel strips have good elongation, toughness, no oxide scale on the machined surface, and good quality, but are more expensive, have a certain degree of work hardening but can achieve a good yield-strength ratio, and are used for cold bending. Parts such as elastic sheets; hot-rolled stainless steel strips have low prices, poor toughness and surface flatness, oxide scale on the surface, poor thickness, good plasticity, soft and easy to bend and deform.
