ASME SA312 TP316 Seamless Steel Square Fin Tube For Boiler , Heat Exchanger
Grade TP316, also known as Type 316 stainless steel, is an austenitic chromium-nickel stainless steel containing molybdenum. This addition enhances the alloy's corrosion resistance, particularly against chlorides and other industrial solvents. TP316 is known for its excellent mechanical properties and high resistance to pitting and crevice corrosion in chloride environments.
ASME SA312 TP316 seamless steel square fin tubes are particularly effective in the chemical processing, oil and gas, marine, power generation, food and beverage, and pharmaceutical industries. Their outstanding performance in corrosive and high-temperature environments ensures long-term reliability and efficiency.
