While numerous variations of stainless steel can be found, the two most popular are austenitic and ferritic. These steels offer a wide breadth of use cases ranging from automotive manufacture to food processing. Austenitic types do not demonstrate any magnetic traits while possessing excellent resistance to corrosion. On the other hand, ferritic types have a strong magnetic presence and proficient rustproofing capabilities. Both are widely utilized in the construction industry.
ASTM Interational – formerly known as the American Society for Testing and Materials – operates as an international standards organization, releasing and distributing voluntary standards for materials, products, services, and systems. These ASTM stainless steel standards are 100% complimentary to view or download from their website.
Named ASTM A312, A358, and A790, these are the respective standard specifications assigned for welded-in and -out, and heavily processed austenitic stainless steel tubes; electric-fusion-welded chromium-nickel stainless steel piping; and both seamless and welded ferritic/austenite stainless steel conduits.
Revealing strength and resilience, illustrious ASTM stainless steel pipe standards present criteria for excellently crafted austenitic and ferritic stainless steel pipes of various sizes and wall thicknesses. Specifying maximum allowable stress and temperature ratings for each remarkable grade of pipe, these standards are models of excellence.
The ASTM A312 austenitic stainless steel pipe is often employed in operations requiring an elevated temperature or pressure. Common grades of this type of pipe are 304, 304L, 316, and 316L.
In highly corrosive and temperature-specific settings, ASTM A358-classified Electric Fusion Welded Austenitic Chromium-Nickel Stainless Steel Piping is often employed. Most commonly, this type of piping is found in 304, 304L, 316, and 316L grades.
ASTM A790 pipes made from ferritic/austenitic stainless steel are frequently used in strenuous and chemical-heavy settings. This tubular material normally comes in 304, 304L, 316, and 316L varieties, each exhibiting particular traits in terms of strength and durability.
