Common Types of ASTM A312 Stainless Steel Seamless Pipes
The ASTM A312 standard includes seamless and welded austenitic stainless steel pipes used for high temperature and/or corrosive environments (the most common grades are 304/304L and 316/316L). In this article, the chemical and mechanical properties of the ASTM A312 requirements are discussed.
ASTM A312 Stainless Steel Seamless Pipes are used for high-temperature applications where corrosion is a major issue. Stainless steel was produced at the beginning of the century to meet the growing demand, across many industries, for more robust steels that could survive challenging service environments. Stainless steel was developed as an evolution of regular carbon steel and was created by the addition of alloy elements to base iron such as nickel and chromium. The introduction of such alloy elements increases the tolerance of the steel to corrosion in rough environments.
Before moving through different grades, let’s look at the types of stainless steel available in the market and their classification.
