The specified mechanical requirements for ASTM A335 P22 include a minimum tensile strength of 415 MPa, minimum yield strength of 205 MPa and minimum elongation of 30%.
| Mechanical Property | Minimum Requirement |
|---|---|
| Tensile Strength | 415 MPa / 60 ksi |
| Yield Strength | 205 MPa / 30 ksi |
| Elongation | 30% |
These values form part of the material verification requirements for P22 pipe supplied against the specified grade.
Reference dimensional range for ASTM A335 P22 pipe:
| Dimension | P22 Pipe Range |
|---|---|
| Nominal Bore | 1/2" NB to 36" NB |
| Wall Thickness | 3–12 mm |
| Cold Drawn Tolerance | ±0.1 mm |
| Cold Rolled Tolerance | ±0.05 mm |

For buyers reviewing mill test certificates, the key P22 mechanical values are:
| Test | Minimum Value |
|---|---|
| Tensile Strength | 60 ksi / 415 MPa |
| Yield Strength | 30 ksi / 205 MPa |
| Elongation | 30% |
The 205 MPa minimum yield strength and 415 MPa minimum tensile strength provide measurable acceptance criteria when reviewing the mechanical test results supplied with the pipe.

| Tempering Temperature Reference | 1250°F [675°C] |
Ganpat Metal supplies P22 in configurations used for different fabrication and piping requirements:
Seamless P22 pipe is specifically covered under the ASTM A335 specification for ferritic alloy steel pipe intended for high-temperature service.
The P22 range can be specified in different forms and end preparations.
Pipe forms:
End finishes:
Square and rectangular configurations can be specified for requirements using P22 square pipe or P22 alloy steel rectangular pipe rather than conventional round piping.
P22 procurement can involve testing beyond the standard mechanical and chemical verification, particularly where the project specification includes IBR, sour-service or hydrogen-service requirements.
The additional testing options supplied for P22 include:
For an enquiry involving these tests, the required testing should be identified together with the grade, size, schedule and quantity so the quotation corresponds to the actual inspection scope.
The P22 grade is selected for piping requirements involving elevated temperatures and alloy steel construction.
The combination of chromium and molybdenum makes P22 distinct from lower-alloy carbon steel piping when the project specification calls for a Cr-Mo alloy steel grade.
Ganpat Metal manufactures and supplies ASTM A335 P22 Pipes in India from 1/2" NB to 36" NB, with 3–12 mm wall thickness listed in the supplied product range.
Buyers can specify:
This level of specification helps the quotation reflect the actual P22 pipe configuration instead of treating all P22 pipes as the same product.
Ganpat Metal supports ASTM A335 P22 pipe requirements for domestic and international industrial projects. Export quotations can be prepared according to the required grade, dimensions, quantity and documentation.
