304 stainless steel is a versatile stainless steel material with stronger rust resistance than the 200 series stainless steel. It has good high temperature resistance, which can withstand temperature as high as 1000-1200 degrees. 304 stainless steel also has excellent stainless corrosion resistance and good resistance to intergranular corrosion.
With pickling and hot-rolling, the stainless steel coils has bright and anti-corrosion surface, low hardness, easy processing and good ductility.
Chemical Composition of Stainless Steel Coil
What are the differences between 304, 304L and 304H?
In fact, the content of chromium and nickel is 304 stainless steel, the composition contains 18% chromium (Cr), 8% nickel (Ni), but the main difference is the difference in carbon content.
304L is ultra-low carbon stainless steel, the carbon content is reduced to less than 0.03%, which can avoid intergranular corrosion, and theoretically the effect of stress corrosion resistance is stronger than 304, but the effect is not obvious in practical applications. The purpose of reducing carbon and adding titanium is the same, but the 321 smelting cost of adding titanium is relatively high, the molten steel is thick, and the price is relatively expensive.
H in 304H refers to high temperature, high carbon content is the guarantee of high temperature strength, GB150 requires austenitic steel to be used at 525 degrees or more, carbon content is not less than 0.04%, carbide is strengthening phase, especially high temperature strength Better than pure austenite.
Among the three, the highest carbon content is 304H, and the lowest carbon content is 304L, while the 304 stainless steel has a carbon content between the two. The higher the carbon content, the worse the corrosion resistance of stainless steel and the easier it is to rust. The difference in carbon content also causes the price to vary, or the different requirements of the sentence.
APPLICATIONS OF 304 STAINLESS STEEL
This grade of stainless steel is the general purpose austenitic stainless steel used in chemical processing, pulp and paper mills, and many other industries such as food and dairy, where its corrosion resistance is suitable and adequate.
