ASTM A312

Austenitic Stainless Steel Seamless and Welded Pipe.

ASTM A312 Standards And Specifications

The ASTM A312 covers Stainless Steel Seamless and Welded Pipe which are used in flue gas cleaning and desalination.

ASTM A312 - Seamless Pipe and Welded Pipe

ASTM A312 Pipe

ASTM A312 is a seamless and welded pipe of stainless steel. These pipe are custom made as per requirement of application. The size of seamless pipes are 1/8 inch to 36 inch NB (Nominal Bore) and 10.3 mm to 914.4mm OD (Outer Diameter) in round, square and rectangular forms. The welded pipe comes in 48 inch NB to and 1,219.2mm OD (Outer Diameter) available in round, square, hydraulic, rectangular, etc. forms.

Scope And Manufacturing

ASTM A312 specification covers seamless pipe and welded pipe for austenitic stainless steel. These high performance austenitic stainless steels have a fully austenitic microstructure in the quench annealed condition. These grades are sometime alloyed with nitrogen to improve strength or with sulphur to improve machinability. 904L was originally developed to withstand environments involving dilute sulphuric acid and it is one of the few stainless steels that, at temperatures up to 35°C, provides full resistance. This is mainly due to the high contents of chromium, nickel, molybdenum and nitrogen.

Siddhagiri Metals and Tubes offers austenitic grades such as 316h Stainless Steel, 316ti Stainless Steel, 317l Stainless Steel, 330 Stainless Steel, 904l Stainless Steel. These grades are used in seawater handling, hydrometallurgy, food and beverage, pharmaceuticals and heat exchangers. Our steel product is made under the professional expertise which gives good quality and excellent strength.


ASTM A312 is a standard specification for austenitic Stainless Steel Seamless Pipe and Welded Pipe. These are high performance austentic stainless steels which have good weldability and excellent formability.
