Stainless Steel Pipe & Tube Grades

Stainless 304

304 is an 18 percent chromium and 8 percent nickel grade of stainless steel. It is one of the most commonly used grades thanks to its useful mechanical properties and low cost. Data Sheet Technical Question? Get a Quote

Stainless 304L

304L is the low carbon version of 304. All tubular products are readily available in 304L stainless steel Data Sheet Technical Question? Get a Quote

Stainless 304H

Like standard 304, this grade is also an 18 percent chromium and 8 percent nickel stainless steel. This grade requires a minimum carbon content of .04. The higher carbon content gives 304H greater heat resistant qualities, higher yield strength, and better short-term and long-term creep strength. Longer lead times could be required to deliver 304H in some tubular forms. Data Sheet Technical Question? Get a Quote
