ASTM A312 is a specification established by the American Society for Testing and Materials (ASTM) that covers seamless, welded, and heavily cold-worked austenitic stainless steel pipes used in various industries.

OD: NPS 1/8″ to 30″
WT: SCH 5S, 10S, 40S, 80S
Grade: TP304, TP304L, TP316, TP316L, TP309S, TP310S, TP317,TP317L,TP321,TP347,TP348,904L, 6%Mo (UNS S31254, UNS N08367, UNS N08926), 7%Mo (UNS S32654), 4%Si (UNS S30600), 5%Si (UNS S30601), 5%Si (UNS S32615), 6% Si (UNS S38815)

This specification covers seamless, straight-seam welded, and heavily cold worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service. ASTM A312 316L properties and ASTM A312 316L chemical composition are listed in the ASTM A312 specification.

The A312 standard specifies the dimensions, mechanical properties, and testing requirements for stainless steel pipes. It primarily focuses on austenitic grades of stainless steel, such as 304, 304L, 316, 316L, and their variations.

The pipes manufactured under ASTM A312 are commonly used in applications requiring corrosion resistance, high-temperature strength, and excellent mechanical properties. These pipes find extensive use in industries like chemical processing, oil and gas, food processing, pharmaceuticals, and many others.

ASTM A312 stainless steel pipes can be produced in different sizes, ranging from small nominal diameters to large ones, with varying wall thicknesses. The manufacturing methods include seamless and welded processes, depending on the specific requirements of the application.

Overall, ASTM A312 stainless steel pipes are widely recognized for their durability, corrosion resistance, and suitability for various demanding environments, making them a popular choice in numerous industrial applications.
