Generally, stainless steel and heat-resistant cold-rolled stainless steel strips with a thickness between 0.01 and 1.5mm and a strength between 600 and 2100N/mm2 are collectively referred to as high-strength stainless steel precision strips. This and the thickness of the cold rolled strip in the range of 0.3-1.5mm (slitting) in the size of the overlap, but only special rolled slitting stainless steel strip to meet the special requirements of stainless steel precision strip. High strength stainless steel precision strip belongs to the category of stainless steel specialization, taking into account the huge demand and few measurement parameters, combined with the actual processing of stainless steel strip and other specific conditions, the characteristics of stainless steel precision strip is mainly defined as the width below 600mm, thickness accuracy 0.001mm, width accuracy 0.1mm (Japan East Ocean standard). The surface quality of the stainless steel precision steel strip must be able to meet the needs of different users, such as the 2B surface of the stainless steel strip with the thickness Ra≤ 0.16mm, the BA surface with the thickness Ra≤ 0.05mm or other special surfaces. In addition, the mechanical properties of stainless steel precision strip are also very high, and the yield strength can be specified according to the different needs of users.
