Features
The most important elements in 304 stainless steel strip are Ni and Cr, but they are not limited to these two elements. The specific requirements are stipulated by the product standards. The common judgment in the industry is that as long as the Ni content is greater than 8% and the Cr content is greater than 18%, it can be considered as 304 stainless steel. 304 stainless steel strip has good corrosion resistance, heat resistance, low-temperature strength and mechanical properties. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids. It is resistant to corrosion in the atmosphere. If it is an industrial atmosphere or a heavily polluted area, it needs to be cleaned in time to avoid corrosion. It is suitable for food processing, storage and transportation. Has good processing properties and weldability.
