What is the difference between 409 and 430 stainless steel?
409 stainless steel plate has poor thermal conductivity and low elongation compared to ordinary low-carbon steel, which leads to large deformation force required for shearing and bending; 321 stainless steel sheet has a strong rebound tendency compared with carbon steel when bending; stainless steel plate has a lower elongation than carbon steel, so the bending angle R of the workpiece should be greater than that of carbon steel when bending, otherwise there is a possibility of cracks.

The difference between 202 stainless steel and 304 stainless steel is?
202 stainless steel and 304 stainless steel are related in one piece, the main reason is that both are basically austenitic stainless steel structure, without magnetic, the appearance of the difference is not big, but the important difference is the content of the metal element nickel, which leads to the huge difference between the two in performance and price.

Cold-rolled coil is one of the most important stainless steel, through the differentiation of production process can be divided into cold-rolled stainless steel coil and hot-rolled stainless steel coil two categories, and through the differentiation of raw materials can be divided into austenite, ferrite, martensite and biphase cold rolled coil of several raw materials. As with other forms of stainless steel, cold-rolled coil has strong corrosion resistance and rust resistance, and excellent product quality makes it a very important chemical raw materials and building materials. With the continuous development of social economy, the application range of cold-rolled coil is more and more common, and the market demand is particularly concerned by the industry. The following small series will introduce you to the use of cold rolled coil.

The difference between 304 and 304l stainless steel
304 stainless steel is the most widely used steel. As a type of steel with a wide range of applications, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; it has good hot processing properties such as stamping and bending, and no heat treatment process hardening phenomenon (non-magnetic, convenient temperature -196℃～800℃).
