A514 Plate Mechanical Properties

A514	Thickness mm	Yield Strength Min Mpa	Tensile Strength Mpa	Elongation Rate Min%
	≤ 20	≥ 690	760-895	≥ 18
	20-65	≥ 690	760-895	≥ 18
	65-150	620	690-895	18

*Design & Procurement Insight
A yield strength of 690 MPa allows for thinner, lighter sections compared to standard carbon steel. This can reduce material tonnage and logistics costs by up to 25–30%, especially in weight-sensitive designs such as long-span bridges or mobile crane booms.
