304,304H and 304L, What is the difference?
In fact, according to the content of chromium and nickel ,they are all 304 stainless steel, the composition is containing 18% chromium (Cr), 8% nickel (Ni), but the main difference is the percentage of carbon between them.

304, 304L, 304H chemical composition (%) table
304L is ultra-low carbon stainless steel, the carbon content is down to 0.03% or less, to avoid intergranular corrosion, and the effect of stress corrosion resistance is better than 304 in theory, but in practice the effect is not obvious. Reducing the carbon and adding titanium can achieve the same effect, but adding titanium which is 321 stainless has higher smelting costs, the price is more expensive.
