A709Gr50 H Section Beam
A709Gr50 Steel Beam H
A709Gr50 high strength low alloy steel American Standard steel for bridges, also known as low alloy steel.
A709Gr50 elements on the alloy impact: alloying elements on the quenching and tempering of steel in the case of the most significant role in strengthening, because it makes full use of all the four strengthening mechanism. Quenching constitutes martensite, tempering carbide, constituting a strong second phase strengthening, together with the resistance greatly improved, so the martensite and tempering is the most economical and most useful generalized steel strengthening methods.
A709Gr50 h beam is widely used in engineering structures, such as building steel structure, construction machinery, mining machinery, trucks, bridges, pressure vessels, etc., especially for the requirements of good weldability and toughness of construction and engineering machinery components.
