Features
430 stainless steel strip refers to a 430 stainless steel strip with a width of 600mm or less, also called 430 stainless steel strip or 430 stainless steel strip. 430 stainless steel strip can be divided into two annealing states: cold-rolled and hot-rolled. The thickness range of 430 cold-rolled steel strip is 0.038-3.0mm; the thickness of hot-rolled steel strip is 3.0-6.0mm, and more than 6.0mm are mostly plates. 430 stainless steel belt is actually a kind of rolling material, generally produced by stainless steel rolling manufacturers. The definition of steel strip in my country has changed several times with the change of stainless steel production equipment. When the rolling mill had a narrow width earlier, the 430 stainless steel strip represented a strip material with a width of less than 300 mm. With the widespread use of rolling mills above 600mm in mainland China, the definition of steel strip has evolved into a strip material within 600mm.
