304 Stainless Steel Watch Strap Cold Rolled ASTM JIS High Quality
From the rolling process and product status of stainless steel, stainless steel can be divided into two categories: cold rolled and hot rolled, namely the so-called stainless steel cold rolled coil and stainless steel hot rolled coil, and stainless steel hot rolled coil can be divided into black HRC and white HRC. What we usually call stainless steel hot rolling mainly refers to the white leather in stainless steel hot rolling.
Stainless steel hot-rolled (ie, stainless steel hot-rolled white skin) has two main purposes, one is used directly as a finished product, mainly used in industrial fields; the other is used as a raw material for cold-rolled products, through annealing, pickling, Cold rolling and other processing procedures are rolled into stainless steel cold rolled coils.
According to the width of the cold-rolled material, the cold-rolled stainless steel is divided into two parts: the real material and the narrow strip. The positive material refers to the stainless steel cold-rolled product with a width of more than 1000mm, and the stainless steel cold-rolled material with a width of less than 1000mm is collectively referred to as stainless steel narrow strip.
Generally speaking, stainless steel cold-rolled materials are mostly used in civilian industries. If downstream enterprises want to maximize their benefits, they must control production costs. The price difference between stainless steel raw materials and narrow strips just provides a living space for the stainless steel narrow strip industry. .
From the perspective of steel classification (according to the nickel content and composition), stainless steel can be divided into 200 series, 300 series and 400 series. Among them, the 300 series are high-nickel products, and the 400 series are nickel-free products. Due to the high price of 304, some enterprises have certain requirements for the corrosion resistance of stainless steel, which led to the birth of the 200 series. In some applications, 200 series stainless steel products can replace some high-priced steel grades
