Is stainless steel good or does not contain copper?
Specific depends on what your product used in products, if the product performance requirements are not high, half copper stainless steel also has a certain market space. But for higher physical properties and processability, it is recommended to use high copper material or higher quality materials (such as 202#, 304#, 316#, etc.)
Regular stainless steel contains a certain amount of copper. For example, 201#, half copper content is about 0.7%-0.8%., while high copper is 1.4%-1.5%. In contrast, the high copper content, tensile properties and rust resistance will be higher.
Stainless steel is a mixture of various materials, copper is one of the materials, there is no copper, there will be no stainless steel, copper in stainless steel inside the proportion, copper too much, stainless steel on the soft, too little, crisp.
