 ASTM A376 ASME SA376 Stainless Steel Pipe & Tube Specification

Spec. No.

Title

Scope

ASTM A376  ASME  SA376

Seamless Austenitic Stainless Steel Pipe for High-Temp Central-Station Service.

Austenitic stainless steel pipe intended for high temperature and general corrosive service. Better surface than A312 pipe.

This specification covers seamless austenitic steel pipe intended for high-temperature central-station service. The grades covered are five H grades and two nitrogen grades. Pipe may be either hot finished or cold finished, with a suitable finishing treatment. All pipes shall be furnished in the heat-treated condition unless the order specifically states that no final heat treatment shall be applied. Tensile tests, hydrostatic test, nondestructive electric tests, ultrasonic tests, eddy-current tests, tension tests, and flattening tests shall be made to conform to the requirements specified.

Scope

1. This specification covers seamless austenitic steel pipe intended for high-temperature central-station service. Among the grades covered are H grades and nitrogen grades that are specifically intended for high-temperature service.

2. Optional supplementary requirements (S1 through S10) are provided.

3. Grades TP321 and TP321H have lower strength requirements for nominal wall thicknesses greater than 3/8 in. [9.5 mm].

4. The dimensionless designators NPS (nominal pipe size) and DN (Diametre Nominel) have been substituted in this standard for such traditional terms as “nominal diameter,” “size,” and “nominal size.”

304H Stainless Steel Pipe Properties

Heat Resistance:

  •  Suitable for high temperature applications, as it offers higher strength at temperatures above 500° C and up to 800° C
  • Grade 304H offers good oxidation resistance in intermittent service to 870° C and in continuous service to 920° C
  • Becomes sensitized in the temperature range of 425-860° C; hence not recommended if aqueous corrosion resistance is required.

Corrosion Resistance:

  • Good resistance to corrosion in oxidizing environments, and moderately aggressive organic acids due to the presence of chromium and nickel respectively
  • Performs uniformly in most corrosive environments
  • May show lower corrosion rate compared to higher carbon grade 304.

Weldability:

  •          Readily welded by most standard processes.
  •          May be required to anneal after welding
  •          Annealing assists in restoring the corrosion resistance lost by sensitization.

Processing:

  •          Recommended working temperatures of 1652-2102° F
  •          Pipes or tubes should be annealed at 1900° F
  •          Material should be water quenched or rapidly cooled
  •          304H grade is quite ductile and forms easily
  •          Cold forming helps increase strength and hardness of grade 304H
  •          Cold forming may make alloy slightly magnetic

Applications of Grade 304H Stainless Steel Pipes

Some examples of applications that grade 304H is commonly used for includes:

  •          Petroleum refineries
  •          Boilers
  •          Pipelines
  •          Heat exchangers
  •          Condensers
  •          Steam exhausts
  •          Cooling towers
  •          Electric generation plants
  •          Occasionally used in fertilizer and chemical plants
