304L Stainless Steel Pipe belongs to the same 300 series stainless steel pipe, 304/304L stainless steel pipe is the most widely used a chromium-nickel stainless steel, as a widely used steel, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; stamping, bending and other hot workability, no heat treatment hardening phenomenon (use temperature -196 ℃ ~ 800 ℃).The main difference between 304 and 304L is that 304L stainless steel pipe contains much less carbon than 304 and is more resistant to corrosion. 304L is better than 304 in terms of resistance to pitting at welded points or other treatments.
