ASTM A514/A514M High-Yield-Strength Steel Plate Overview

ASTM A514/A514M High-Yield-Strength Steel Plate Overview

ASTM A514/A514M is the standard specification for high-yield-strength, quenched and tempered alloy steel plates suitable for welding. These plates are designed for structural applications requiring exceptional strength, with a minimum yield strength of 100 ksi (690 MPa) for most thicknesses, making them ideal for reducing weight in heavy-duty constructions.

As a leading manufacturer and exporter, Gangsteel provides high-quality ASTM A514/A514M steel plate in various grades to meet global engineering demands.

What is ASTM A514/A514M Steel Plates?

The ASTM A514/A514M specification covers 14 grades (A, B, C, E, F, H, J, K, M, P, Q, R, S, T) of alloy steel plates that are quenched and tempered to achieve high yield strength. These plates are primarily used in welded bridges, buildings, and other structures where high strength and good weldability are essential. The high-yield-strength property allows for lighter designs without compromising durability, and the plates are available in thicknesses up to 8 inches for select grades. Gangsteel's production includes popular grades like astm a514 grade b and astm a514 grade q, ensuring compliance with the latest ASTM standards.

The following table provides an overview of common ASTM A514 grades, their typical thickness ranges, and key features:

These grades are grouped in the standard for chemical requirements, with variations to suit specific needs.

Chemical Composition of ASTM A514/A514M Steel Plates

The chemical composition is tightly controlled to ensure the high-yield-strength and other properties. Below is a table of chemical requirements (in weight %, heat analysis) for select grades, based on ASTM A514/A514M:

Note: Dashes indicate no specified requirement. For grades like astm a514 grade j and astm a514 grade t, compositions are similar to grouped categories in the standard.

Mechanical Properties of ASTM A514/A514M Steel Plates

Mechanical properties are uniform across most grades but vary with thickness. The plates offer high tensile and yield strength, with good elongation for ductility. Below is a summary table:

For example, astm a514 grade f and astm a514 grade h maintain these properties in abrasive and high-impact settings.

Heat Treatment and Processing

ASTM A514/A514M plates must be quenched and tempered, with tempering at a minimum of 1100°F (590°C) to achieve the required strength and toughness. This process enhances wear resistance and machinability. Testing includes tensile, bend, and optional Charpy V-notch impact tests.

Applications and Benefits

These steel plates are used in cranes, mining equipment, bridges, and offshore platforms due to their high strength-to-weight ratio. Benefits include durability, cost savings from reduced material use, and excellent weldability when following proper procedures.
