An established producer and exporter of SS 304 pipes and tubes that no longer respond to heated solutions is Nandini Steel. In terms of power and corrosion resistance, it is superior to stainless. It is renowned for having exceptional power and oxidation resistance at continuous service temperatures of up to 2000 degrees Fahrenheit (1093 Degree C). Cold working can be used to increase strength and hardness. Because stainless steel UNS S30400 Seamless Pipes are entirely made of austenite at room temperature, they cannot be hardened using the heated treatment. When annealed, they are essentially nonmagnetic, but when cold worked, they become slightly magnetic.
Better yield and tensile strengths can be obtained through cold working and no longer need to be accompanied by complete annealing at the higher temperatures where those alloys are employed. Austenitic chromium-nickel steels, such as stainless steel WNR 1.4301 Welded Tubes, provide exceptional corrosion resistance, heat resistance, as well as top performance at both ambient and elevated temperatures. A lower nickel concentration increases resistance to sulphur attack at high temperatures.
