ASTM A312/ASME SA312 TP304/304L Stainless Steel
Overview:
304 Stainless Steel pipe is a cost-effective pipe used for both structural and pressure applications due to its good machinability properties as well as excellent weld-ability characteristics with or without the addition of filler metals. These 304 grades of austenitic stainless steels are the most versatile and widely used stainless steels offers excellent corrosion resistance to a wide range of corrosive environments.
ASTM A312 TP304L has a carbon content of 0.03% or less. This alloy can be used in the as-welded condition without becoming susceptible to intergranular corrosion. ASTM A312 TP304L Stainless Steel are tested in accordance to internationally recognized standards. ASTM A312 Stainless Steel 304L shall be made by a process that does not involved welding at any stage of production. It has excellent features like resistance to corrosion， Prevention of product contamination， Resistance to oxidation， East of fabrication， Excellent formability， Beauty of appearance， Ease of cleaning， High strength with low weight， Good strength and toughness at cryogenic temperatures and Ready availability of a wide range of product forms.
