Super Serritie Welded Tube High Quality

What is Super Ferrtic stainless steel?

It is a kind of ferritic stainless steel which contains low Carbon, Nitrogen and other chemical element.

C + N ≤ 120ppm-400ppm (250ppm, 150ppm).

Characteristics

 With very low carbon and nitrogen---meet the requirement of processing and performance

Niobium titanium dual stabilization---improved welding performance

Chromium content: low chromium (10.5-15%), chromium (15-22%) and high chromium (22-32%);

Advantage

Good abilities of stress corrosion, all kinds of localized corrosion, antioxidant corrosion (including high temperature oxidation resistance)

Low density

Good thermal conductivity: It is 30%-50% Higher than Austenite

Small coefficient of thermal expansion: It is 30%-40% less than Austenite

Big elastic modulus

Good processing properties

Easily bending, stamping, curling, spinning, cold forging and machining

Excellent deep drawability
