409/409l cold rolled stainless steel begins to crystallize after pouring, the supercooling degree of the liquid phase is largely due to direct contact with the surface of the crystallizer, and at the same time, the surface of the crystallizer promotes non-spontaneous nucleation. Therefore, the nucleation rate of the liquid phase is high and the formation rate is high. Fine equiaxed crystals on the surface. The formation of fine equiaxed grains on the surface is rapid, and the carbides of titanium are too short to precipitate.
Hot-rolled 409 409L stainless steel coil is a stainless steel coil commonly used in a variety of applications, including the manufacture of automotive exhaust systems, stoves, chemical equipment, and construction materials. This type of stainless steel coil usually has good corrosion resistance and high-temperature tolerance. If you are looking for suppliers or manufacturers of 409 409L hot rolled stainless steel coils, I believe we are your best choice!

440 Stainless Steel Plate Manufacturers
400 series stainless steel is a type of stainless steel with a ferrite or martensite structure. It has high corrosion resistance and strength and is commonly used in various industrial and daily applications. Compared with 300 series austenitic stainless steel, the 400 series contains no or less nickel and is more economical. The main component includes chromium (usually between 10.5% and 30%), which gives it corrosion resistance.
