ASTM A312 TP310S (UNS S31008) Stainless Steel， Pickled And Annealed
ASTM A312 TP310S Stainless Steel is a specific type of stainless steel pipe that is used in various industries for its durability and resistance to corrosion. It is made from grade TP310S stainless steel alloy， which contains high levels of chromium and nickel for increased strength and heat resistance.
The A312 designation refers to the ASTM A312 standard， which specifies the requirements for seamless and welded austenitic stainless steel pipes used in high-temperature and corrosive environments. TP310S is a specific grade of stainless steel that meets the requirements outlined in this standard.
ASTM A312 TP310S is a high temperature service austenitic stainless steel. It is a highly alloyed material that is used to prevent oxidation and corrosion. This is achieved by the chromium and nickel components in the composition. The TP310S has lower carbon content at 0.08% max where the 310 has 0.24% max of carbon. The material is used for high temperature services with 1150 degrees Celsius at continuous services and at 1035 degrees Celsius with intermittent services.
Key Properties:
1. High temperature resistance: It can withstand high temperatures up to 1150°C (2100°F) without losing its mechanical properties or forming detrimental phases.
2. Corrosion resistance: The high levels of chromium and nickel in the alloy provide excellent resistance to corrosion in various environments， including acidic and alkaline conditions.
3. Oxidation resistance
