ZBH44004-1988 cold, warm rolled ribbon for stainless steel wire rope
Stainless steel wire rope is a commonly used wire rope material. Cold, warm rolled ribbons are essential accessories for stainless steel wire ropes, so the quality of rolled ribbons directly affects the performance of stainless steel wire ropes. This standard specifies the requirements, test methods, inspection rules, signs, packaging, storage and transportation of cold, warm rolled ribbons for stainless steel wire ropes.
This standard is applicable to cold, warm rolled ribbons for stainless steel wire ropes. The stainless steel grades which can be produced are 0Cr25Ni20 and 0Cr17Ni12Mo2, and the strength grade is 0.02-2.25 mm2.
1. Requirements
1.1 Dimensions, Shape and Tolerance
The dimensional tolerance of cold, warm rolled ribbons should meet the requirements of Table 1. The rolled ribbons shall be straight, without obvious cracks and burrs, and the surface is smooth and clean.
1.2 Mechanical properties
The mechanical properties of cold and warm rolled ribbons shall meet the requirements of Table 2.
