A312 TP310S Electric Resistance Welded Tubes
A312 310s austenitic stainless steel pipes supplied by GNEE are inspected multiple times to ensure quality and are available in sizes ranging from 6NB - 1200NB with wall thicknesses ranging from 0.6 - 12.7 mm and even thicker.
A312 310s is an austenitic heat resistant alloy grade designed to resist oxidation and corrosion. This is achieved through the chromium and nickel components in the composition.
A312 310S stainless steel welded pipes are designed with nickel, chromium and low carbon elements to prevent a lot of intergranular corrosion. And have good oxidation resistance and toughness, as well as enhanced corrosion resistance and oxidation resistance.
In addition, A312 stainless steel 310S pipes can work properly in the temperature range of 1000°C to -200°C. This also allows the pipe to be used under high pressure and high temperature. These characteristics allow A312 310S polished pipes to be used in burners, hydraulic systems and boiler tubes.
