TP316L is derivative steel of 18-8 type austenitic stainless steel. It has excellent corrosion resistance, so it has a wide range of applications in the chemical industry. Due to the addition of Mo content, this steel has excellent pitting resistance and can be safely used in environments containing halogen ions such as Cl-. The main difference between TP316 and TP304 in chemical composition is that 316 contains Mo, and it is generally recognized that 316 has better corrosion resistance and is more resistant to corrosion in high-temperature environments than 304. Therefore, in high-temperature environments, engineers generally choose 316 material components.
Therefore, 316L stainless steel heat exchange tubes are widely used in boiler heat exchangers in petroleum, chemical, natural gas, medicine and food, urea fertilizer, and other fields.
