The characteristic of stainless steel pipe
Stainless steels are highly alloyed materials; Stainless Steel is a common name for metal alloys that consist of 12% or more Chromium (Cr) and more than 50% Iron (Fe). Modern stainless steel pipe may also contain other elements, such as nickel, niobium, molybdenum, and titanium. Nickel, molybdenum, niobium, and chromium enhance the corrosion resistance of stainless steel. It is the addition of a minimum of 12% chromium to the steel that makes it resist rust, or stain 'less' than other types of steel. The chromium in the steel combines with oxygen in the atmosphere to form a thin, invisible layer of chrome-containing oxide, called the passive film
The challenge of cutting stainless pipe
All metals works harden when cold worked. Stainless pipe have hardening characteristics as well. When the stainless pipe,stainless tube cutter contact the surface of stainless steel pipe, it will harden and will be more and more difficult to continue on cutting with the same pressure and speed. The chromium and nickel content makes it more difficult to cut or torch than regular carbon steel. Austenitic stainless steels pipe harden very rapidly, but the 400 Series' cold working rate is only a little higher than that of the plain carbon steels.
