Chemical Properties

UNS Number	Carbon	Silicon	Manganese	Phosphorus	Sulfur	Nickel	Chromium	Molybdenum	Copper	Vanadium

Note A: For each reduction of 0.01 % below the specified maximum carbon content, an increase of 0.04 % manganese above the specified maximum will be permitted up to a maximum of 1.10 % for LCA, 1.28 % for LCB, and 1.40 % for LCC.

Note B: Specified Residual Elements—The total content of these elements is 1.00 % maximum.

Mechanical Properties

UNS Number	Tensile strength, ksi [MPa]	Yield strength,^C min, ksi [MPa]	Elongation in 2 in. [50 mm], min, %^D	Reduction of area, min, %

Note C: Determine by either 0.2 % offset method or 0.5 % extension-under-load method.

Note D: When ICI test bars are used in tensile testing as provided for in Specification A703/A703M, the gage length to reduced section diameter ratio shall be 4 to 1.
