What is the difference between stainless steel ASTM A403 304 304L 304H pipe fitting? 304 is between 8% and 11%, while 321 is between 9% and 12%. The carbon content is reduced to below 0.03%, which can avoid intergranular corrosion, and in . Type 304 and 304L have very similar chemical and mechanical properties. Hence, grade 303 is referred to as the free-machining grade of 304 stainless steel. No. This range of carbon in the steel affects the corrosion resistance of the tanks. This range of carbon in the steel affects the corrosion resistance of the tanks. It is important to distinguish because the selection of the right grade will lead to an effective operation in industries. The carbon content is reduced to less than 0.03%, which . The lower carbon content in 304L minimizes deleterious or harmful carbide precipitation as a result of welding. The Difference Between 304, 304L, and 304H Stainless Steel. When comparing the chemical composition of 321 SS and 304/304L SS, it is clear that the chromium (Cr) and nickel (Ni) ranges of these alloys are very similar. 304L has a maximum of 0.3% carbon and 304H has between 0.04 and 0.1% carbon which affords it a better strength at higher temperatures. They are similar in corrosion resistance, strength, hardness and welding performance, but 321 is mostly used in the heat resistance condition of 500-600 ℃. 304L can, therefore, be used "as welded" in severe corrosion environments, and it eliminates the need for annealing. 304 vs 316 Stainless Steel - 7 Differences. - it has somewhat lower mechanical properties than the standard .
