ASTM A234 specification covers wrought carbon steel and alloy steel fittings of seamless and welded construction covered by the latest revision of ASME B16.9, B16.11, MSS-SP-79, MSS-SP-83, and MSS-SP-95. These fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures.

Chemical Composition (%) of ASTM A234

GENERAL NOTE:
All values are maximum unless otherwise indicated.

NOTES:

1. For each reduction of 0.01% below the specified C maximum, an increase of 0.06% Mn above the specified maximum will be permitted, up to a maximum of 1.35%.
2. The sum of Cu, Ni, Cr, and Mo shall not exceed 1.00%.
3. The sum of Cr and Mo shall not exceed 0.32%.
4. The maximum carbon equivalent (C.E.) shall be 0.50, based on heat analysis and the formula C.E.=C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15.

Mechanical properties of ASTM A234

Where the wall thickness lies between two values above, the min elongation value is determined by the following equations:

Longitudinal E=48t+15.00
Transverse E=32t+10.00
E = elongation in 2in [50mm], %
t = actual thickness of specimen, in [mm]
