ASTM A213 TP321 stainless steel boiler tubes are mainly composed of elements such as iron, chromium, nickel and titanium. The chromium content gives it good corrosion resistance, while nickel improves its oxidation resistance at high temperatures.
The production process of ASTM A213 TP321 high-pressure tubes includes steps such as smelting, continuous casting, rolling, heat treatment and surface treatment. The inner and outer surfaces of the tubes are polished, pickled or coated to meet the requirements of different uses.
ASTM A213 TP321 heat exchanger tubes can withstand high temperatures of 1000 degrees for long-term use and are widely used in heat exchangers, condensers, evaporators and other equipment in the chemical, petroleum, electric power, pharmaceutical and other industries.
