ASTM A312 Pipe

What is ASTM A312?

Stainless or rust-free steel revolutionized the industrial world from 1913 for over 110 years. Adding over ten percent of chromium to iron made this magic happen for use in many sectors, such as pipes, tubes and others. There are many stainless-steel types depending on the chemical composition of chromium, nickel, molybdenum and others.

ASTM A312 pipe is American standard, has molybdenum to add strength and has high corrosion resistance. It has 16 to 18% chromium and 10 to 14 % nickel to be helpful in high temperature corrosion resistance applications.

ASTM A312 Pipe Specification

ASTM A312 Pipe Properties

Which pipe is specified in the A312 material specification?

A312 material specification is for stainless steel pipe used in various industries for its many benefits. After A304, A 312 is the most used stainless steel for its unique chemical composition, best for marine equipment, refineries, and petrochemical plants.

Pipes and tubes made of ASTM A 312 material grades TP304/304L and TP 316/316L have high strength and corrosion resistance. TP 312/316 L with additional molybdenum of 2 to 3% and with more nickel and chromium than TP 304/304L grade. Hence pipes made from TP 316/316L is more robust and corrosion-resistant than TP 304/304L grade. ASTM A 312 specifications are for making seamless, cold worked, straight seam welded pipes and others.

Difference between ASTM A269 and ASTM A312

ASTM A 269 and ASTM A 312 pipes are made from stainless steel and have many similar properties. The A 269 and A 312 steel have the same grades, yield strength, tensile strength, and elongation. But there are also a few differences between the two, including the following, among others.

  • A312 SS pipes are welded and seamless, but A 269 standards are best for tubing than pipes
  • A 312 is best for high-temperature corrosion resistance applications, whereas A 269 is best for elevated-temperature oxidation resistance applications.

What application is ASTM A312 stainless steel pipe used?

ASTM A312 stainless steel pipe is best for high-temperature applications that require expert corrosion resistance. ASTM A312m is available in many grades like TP 304, TP 304L, TP 316, and TP 316L have different chromium and nickel content to have other properties. Hence their applications also vary as per the need for high temperatures with excellent corrosion resistance.

ASTM 312 stainless steel applications include industries like chemical, petrochemical, pharmaceutical, and many others. The A 312 pipes are best for structural applications like support pipes, poles, and handrails for salty or corrosive environments.

What are the additional requirements of A312 pipe material?

ASTM A312 pipe specifications include seamless, austenitic, welded, and cold-worked steel pipes with excellent corrosion resistance. But as per the application need, there are a few additional requirements for the A 312 pipe material. It is to check the strength and corrosion resistance f A 312 pipes to be suitable for the application needs.

The additional requirement for A 312 pipes and tubes is the different tests for checking tensile strength and others. A few mechanical tests include heat-treated conditions, flattened tests, and transverse or longitudinal tension tests.
