ASTM A269 TP316 Tubing Heat Treatment Requirements

  • All material shall be furnished in the heat-treated condition. Except as provided in 6.2, the heat-treatment procedure shall, except for S31254 and S32654, S24565, N08367, N08904 and N08926, consist of heating the material to a minimum temperature of 1900°F (1040°C) and quenching in water or rapidly cooling by other means. Alternatively, for seamless tubes, immediately following hot forming while the temperature of the tubes is not less than the specified minimum solution treatment temperature, tubes may be individually quenched in water or rapidly cooled by other means.
  • Controlled structural or special service characteristics shall be specified as a guide for the most suitable heat treatment. If the final heat treatment is at a temperature under 1900°F and is so specified on the order, each tubes shall be stenciled with the final heat treatment temperature in degrees Fahrenheit after the suffix ”HT”.
  • S31254 and S32654 shall be heat-treated to a minimum temperature of 2100°F (1150°C) followed by quenching in water or rapidly cooling by other means.
  • S24565 SHALL BE HEAT-TREATED IN THE RANGE 2050°F (1120°C) to  2140°F (1170°C) followed by quenching in water or rapidly cooling by other means.
  • N08904 shall be heat treated to a minimum temperature of 2000°F (1100°C) followed by quenching in water or rapidly cooling by other means.
  • A solution annealing temperature above 1950°F (1065°C) may impair the resistance to intergranular corrosion after subsequent exposure to sensitizing conditions in TP321, TP347, and TP348. When specified by the purchaser, a lower temperature stabilization or re-solution anneal shall be used subsequent to the initial high temperature solution anneal.
  • N08926 shall be heat-treated to a minimum temperature of 2010°F (1100°C) followed by quenching in water or rapidly cooling by other means.
  • UNS N08367 should be solution annealed from 2025°F (1107°C)minimum followed by rapid quenching.
  • Solution annealing of S35045 shall consist of heating the material to a temperature of 2000°F (1093°C) minimum for an appropriate time, followed by cooling in still air or at a faster rate.

Flaring Test (Seamless Tubes)

One test shall be made on specimens from one end of one tube from each lot of finished tubes.

Flange Test (Welded Tubes)

One test shall be made on specimens from one end of one tube from each lot of finished tubes.

Hardness Test

Brinell or Rockwell hardness determination shall be made on specimens from two tubes from each lot. The term lot applies to all tubes prior to cutting, of the same nominal diameter and wall thickness that are produced from the same heat of steel. When final heat treatment is in a batch-type furnace, a lot shall include only those tubes of the same size and the same heat which are heat treated in the same furnace charge. When the final heat treatment is in a continuous furnace or when the heat-treated condition is obtained directly by quenching after hot forming, a lot shall include all tubes of the same size and heat, heat treated in the same furnace at the same temperature, time at heat, and furnace speed, or all tubes of the same size and heat, hot formed and quenched in the same production run.

Reverse flattening Test

For welded tubes, one reverse flattening test shall be made on a specimen from each 1500ft(460m) of finished tubing. Coiled tubing greater than 1500ft(450m) in length shall be sampled at both ends, a coil must be continuous without any circumferential butt welds.

Hydrostatic or Nondestructive Testing

Each pipe shall be subjected to the nondestructive electric test or the hydrostatic test.

Markings

  • Markings will adhere to prescribed specifications in ASTM A1016/A 1016M and shall include whether the tubing is seamless or welded and the final heat-treatment temperature in digress Fahrenheit after the suffix” if the final heat treatment temperature is under 1900°F (1040°C).
  • When the nondestructive electric test is performed, each length of tubing shall be marked with the letters “NDE” and the certification, when required, shall also indicate this test.

Note:

  • Mill test certificates will be issued according to EN10204 3.1
  • All tubes shall be supplied as per applicable ASTM A269 Specification.
