A524 Seamless Low-Carbon Steel Pipe for Atmospheric and Lower Temperatures

1. Material Overview

ASTM A524 (also designated A524/A524M-21 in its latest revision) defines the standard specification for seamless low-carbon (killed) steel pipe, primarily intended for service at atmospheric and lower temperatures, covering nominal pipe sizes (NPS) from 1/8″ to 26″ with wall thickness per ANSI B36.10

The steel is required to be killed steel, produced via open-hearth, electric-furnace, or basic-oxygen processes. It should follow fine-grain practices, cast as ingots or strand-cast, and can be supplied either hot-finished or cold-drawn depending on size

2. Specifications

Chemical Composition

Mechanical Properties

Distinct ranges for Grades I and II depending on wall thickness:

These pipes also undergo flattening, hydrostatic, bending, and tensile tests as part of quality assurance A

3. Notable Grades

While this spec encompasses two grades, only Grades I and II are standardized for A524. Alternative low-temperature pipes—such as ASTM A333—exist but are distinct standards (not within A524 itself)

4. Execution Standards

• ASTM A524 (A524/A524M-21) is the primary reference standard

• Designation includes both inch-pound and SI units but prioritizes inch-pound unless "M" is specified

5. Application Areas

Broad Applications

A524 pipes are well-suited for:

• Hydraulic and pneumatic systems

• Oil and gas industry pipelines

• Pressure vessels, heat exchangers

• Automotive components and structural use

• Chemical processing, marine, power generation, water supply

Specific Uses Within These Fields

• In oil & gas, for low-temperature fluid transport or cold climates

• In petrochemical plants, as conduit for volatile chemicals

• In power plants, as piping for cold feedwater or low-temperature steam

• In automotive, for hydraulic cylinder tubing or precision hydraulic lines

• In chemical processing, for corrosion-prone or low-temp pipelines
