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