Differences between stainless steel 30403, 30408, and 30409

30408 stainless steel is the most widely used stainless steel with a carbon content of 0.08%

30403 stainless steel is a low-carbon material of 304 stainless steel, with a carbon content of 0.03%

30409 stainless steel is a high carbon material of 304 stainless steel, with a carbon content of 0.09%

30409 stainless steel increases carbon content, enhances the strength of 30408 stainless steel, and makes the austenitic structure more stable, suitable for use in low-temperature environments and non magnetic components.
