  Notes:

  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%.

  The sum of Cu, Ni, Cr, and Mo shall not exceed 1.00%.

  The sum of Cr and Mo shall not exceed 0.32%.

  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.

ASTM A106 Pipe Fitting Elbow Mechanical Properties

Tensile Requirements WPB WPC, WP11CL2 WP11CL1  WP11CL3
Tensile Strength, min, ksi[MPa] 60-85 70-95 60-85  75-100
(0.2% offset or 0.5% extension-under-load) [415-585] [485-655] [415-585]  [520-690]
Yield Strength, min, ksi[MPa] 32 40 30 45
[240] [275] [205] [310]


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]
