A514 Grade Q is for high yield strength, quenched and tempered alloy steel plate of structural quality in thickness of 150mm and under intended primarily for use in welded bridges and other structures. The max thickness of A514 Grade Q is 150mm. in the heat treatment, A514 Grade Q shall be heat treatment by the mill to conform to the tensile and hardness requirements by heating to not less 900 degree and
AISI A514 Grade F Alloy Steel (UNS K11576)Alloy steels are designated by AISI four-digit numbers. They are more responsive to heat and mechanical treatments than carbon steels. They comprise various types of steels having compositions which exceed the limitations of Va, Cr, Si, Ni, Mo, C and B in the carbon steels.

Welding A514 and A 572 - Welding, Bonding & Fastener Dec 21, 2006 · ASTM A 514 Grade Q is a high strength, quenched and tempered steel plate that requires extreme caution for welding. This material is sensitive to cracking during post weld heat treatment.
T-1 is a quenched and tempered alloy structural steel that comes in four grades equivalent to ASTM A514/A517 grades B, F, H, and Q. Mittal Steel owns the trademark "T-1". Here is a link to Mittal Steel literature on ASTM-A514 / T-1Welding ASTM A514 or A514M-05 steel? - The FabricatorEach grade has a unique chemistry and may differ in the maximum thickness to which it is rolled, from 1¼ in. to 6 in. The material thickness affects the mechanical properties. For instance, A514 rolled to 2½ in. or less must have 110-KSI to 130-KSI tensile strength, 100-KSI minimum yield strength, and 18 percent elongation.
