304 is a kind of universal stainless steel, which is widely used to make machines and parts with excellent comprehensive performance (corrosion resistance and formability). In order to maintain the original corrosion resistance of stainless steel, the steel must have a chromium content above 18% and a nickel content above 8%. 302 stainless steel has high compressive strength after cold drawing, but the elongation is slightly weaker than 1Cr17Ni7. Decorative design components for engineering. So what's the difference?
First: No. 302 stainless steel and No. 304 stainless steel can be used for food production, processing, storage and transportation. The national standard of 302 stainless steel is 1Cr18Ni9, which is a skilled stainless steel material for the main use, and it is also a variation of 304 stainless steel with higher carbon content, which gives it higher compressive strength according to cold binding.
Second: the national standard of 304 stainless steel is 06Cr19Ni10, which is a kind of universal stainless steel, which is widely used to make a variety of comprehensive machines and equipment with good abrasive tools, utensils, etc., due to low manganese content, corrosion resistance, production and processing and strong malleability. And the carbon content of 304 stainless steel is lower than that of 302 stainless steel, the chromium content and nickel content are higher than that of 302 stainless steel, so the price of 304 stainless steel is also higher than that of 302 stainless steel.
With the development of contemporary science and technology, we have increasingly high standards for the quality of housing construction. The key to a house's construction lies in its structure and the application of raw materials. The structure is generally designed by technical professional interior designers, and a large number of raw materials depend on our own, so different materials must be selected according to different design schemes, so that the quality of goods will be ensured.
