Gnee Steel Group is one of the leading suppliers and suppliers of high quality TP 446 stainless steel pipes and tubes, providing excellent resistance to inorganic acids, especially those containing chlorides. The high chromium and molybdenum content of this stainless steel makes it extremely resistant to uniform corrosion of organic acids such as formic acid and acetic acid. THE TP446 SS pipes offered by Gnee Steel also provide excellent resistance to inorganic acids, especially those containing chlorides. The circumstance allows the immediate finishing of the workpiece with milling or drilling, so it is not necessary to pick up the material or perform a similar operation beforehand.
446 stainless steel pipe is a 12% chrome stainless steel, designed to be used under welding conditions. Unlike the other grades of 12% stainless chromium, 446 is not vulnerable to extensive hardening through air cooling at high temperatures.
446 stainless steel pipes are stabilized with titanium, 18 percent chromium alloy, and is a ferrite stainless steel designed to resist corrosion in a variety of oxidizing environments, from fresh water to boiling acids.
Which is a heat-resistant austenitic alloy with excellent oxidation resistance in slightly cyclic conditions at 2000 degrees F, a heat-resistant stainless steel with high oxidation resistance and high strength at high temperatures.

Alloy TP 446 seamless pipes have good oxidation resistance and can be used in continuous service up to 1140 degrees C, provided there are no sulfur reducing gases. With its high chromium content, it offers good corrosion resistance to increase high temperature properties.
The high chromium and nickel content of TP 446 Grade pipes, offered by Gnee Steel, provides comparable corrosion resistance, superior oxidation resistance and retention of a higher fraction of ambient temperature resistance.
