304L SS Pipe is resistant to sulphuric acid concentrations up to 5 percent at temperatures as high as 120 Degree f (49 Degree c) at temperatures under 100 Degree f (38 Degree c), this alloy has excellent resistance to solutions of higher concentration. SS 304L Pipe is a molybdenum bearing, low carbon content “l” grade austenitic stainless steel that provides improved corrosion resistance over 304 and 304l stainless steels. 316 Stainless Steel Seamless Pipe has slightly improved corrosion resistance over type 321 stainless steel in strongly oxidizing environments. Type SS 304l Pipe exhibit good machinability and Stainless Steel 304L Pipe have excellent weld-ability characteristics with or without the addition of filler metals. Stainless Steel 304L Welded Pipes has niobium stabilized austenitic chromium-nickel stainless steel which was developed to provide an 18 – 8 type alloy with improved intergranular – corrosion resistance.
