304 / 304L Stainless Steel Tubing
Grades 304 and 304L stainless steel are the most versatile and commonly used austenitic chromium-nickel alloys on the market. The chromium content in the alloy promotes excellent corrosion resistance, high strength-to-weight ratio, and remarkable ductility. As the predominant choice for hydraulic and instrumentation tubing, types 304 and 304L stainless steel possess exceptional welding capabilities.
