ANSON is a leading ASTM A269 stainless steel tube supplier for boiler and pressure vessel, which can supply steel tube of all grade and dimension range. ASTM A269 stainless steel tube main grades are: TP304/TP304L, TP316/TP316L, TP321, etc. This specification covers nominal-wall-thickness, seamless and welded austenitic steel tubing for general corrosion-resisting and low or high-temperature service. All material shall be furnished in the heat-treated condition. Tube product can be either hot or cold finished.
Austenitic steel tube (TP304/TP304L, TP316/TP316L) has good weld performance and high corrosion resistance(including uniform corrosion and localized corrosion, each grade has its special usage area. Allowable working pressures are calculated from an S value of 20 000 psi (137.8 MPa) for ASTM A269 tubing at –20 to100°F (–28 to 37°C).
