ASTM A514/A514M Standard Specification for High-Yield-Strength, Quenched and Tempered Alloy Steel Plate, Suitable for Welding

ASTM A514/A514M standard specification covers high-yield, quenched, and tempered alloy steel plates for use in welded parts and other structures. ASTM A514/A514M Standard main A514 grades: ASTM A514 Grade A, B, E, F, H, P, Q, S, (A514GRA, A514GRB, A514GRE, A514GRQ, A514GRF, A514GRH) and so on.

There are eight different grades of products under the ASTM A514 standard: A514Gr.A, A514Gr.B, A514Gr.E, A514Grade F, A514Grade H, A514Gr.P, A514Grade Q, A514Gr.S. The thickness, chemical composition and properties of different grades of A514 steel are different.

1. ASTM A514 Steel Plate

The steel should be killed steel and should meet the fine austenite grain size requirements of A6/A6M.

In order to meet the tensile and Brinell hardness requirements specified in Table 2, the steel plates shall be heat treated, that is, the steel plates shall be heated to not less than 1650°F (900°C), quenched in water or oil, and not less than 1150°F (620°C) fire.

A514 is a quenched and tempered high strength weldable steel plate under ASTM standards. ASTM A514 plateis characterized by high strength and good weldability. A514 has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; has good corrosion performance and a certain degree of wear resistance. It is mainly used in places where high tensile strength and high yield are required, such as drilling rigs for mining and various construction projects, lifting gears, oil derricks, coal mine hydraulic supports, electric shovels, electric wheel dump trucks, loaders, bulldozers, and all types of cranes. , engineering vehicles, large excavators, offshore drilling platforms, mining equipment, etc.
