ASTM A312/A312m 304L 50*50mm 400g Satin Surface 201 202 304 304L 316 316L 309S 310S 410 420 430 Stainless Steel Square Tube for Building
The letter L following the grade number, such as 304L, indicates that carbon content is limited to 0.03 percent (normal levels are 0.08 percent maximum and in some grades can be up to 0.15 percent maximum).In grade 304 stainless steel, the maximum carbon content is set at 0.08%, whereas grade 304L stainless steel has a maximum carbon content of 0.03%. This is why the "L" in 304L can be interpreted as meaning extra-low carbon.ASTM A312 is a specification for seamless and welded austenitic stainless steel pipes that perform well in high temperature and corrosive environments. The common grades for this specification are 304/304L and 316/316L.
