ASTM A516 Grade 70 Steel Plate

ASTM A516 Grade 70 Steel Plate

ASTM A516 Grade 70 is a carbon steel plate used for pressure vessels and boilers at moderate and lower temperatures. It is commonly selected for its strength, weldability and notch toughness.

Henry Steel supplies A516 Grade 70 steel plate for pressure vessels, boilers, storage tanks and petrochemical equipment. We offer different plate sizes and thicknesses, along with cut-to-size service, inspection, MTCs and export delivery.

ASTM A516 Grade 70 Steel Plate Specification

*Mechanical requirements vary with plate thickness. Refer to the applicable ASTM specification and MTC for actual values.

What Is ASTM A516 Grade 70 Steel Plate?

ASTM A516 Grade 70 is a pressure vessel quality carbon steel plate specified under ASTM A516/A516M. It is used for welded pressure vessels operating at moderate and lower temperatures where good notch toughness is required.

The "70" refers to the grade's tensile strength level, with a minimum tensile strength of 70 ksi (485 MPa).

A516 Grade 70 is commonly used for pressure vessels, boilers, storage tanks and other equipment where strength, weldability and toughness are required.

Key Properties of A516 Grade 70 Steel Plate

High Strength

A516 Grade 70 has a minimum yield strength of 260 MPa and tensile strength of approximately 485–620 MPa, depending on plate thickness.

Good Notch Toughness

Suitable for pressure vessel applications at moderate and lower temperatures, with impact testing available when required.

Good Weldability

A516 Grade 70 is commonly welded for pressure vessel and tank fabrication.

Easy to Fabricate

The plate can be cut, formed, drilled and welded using standard fabrication processes.

ASTM A516 Grade 70 Chemical Composition

ASTM A516 Grade 70 chemical composition is specified under ASTM A516/A516M, including carbon, manganese, silicon, phosphorus and sulfur.

*Actual chemical limits depend on plate thickness and the applicable ASTM A516/A516M requirements. Chemical composition should be confirmed against the MTC and purchase specification.

For HIC-resistant A516 Grade 70, additional chemical and testing requirements may apply.

Delivery Conditions

A516 Grade 70 steel plate can be supplied in normalized, normalized and tempered, or as-rolled conditions, subject to plate thickness, ASTM requirements and purchase specifications.

Normalized: Commonly supplied for pressure vessel applications.

Normalized and Tempered: Available when additional heat treatment requirements apply.

As-Rolled: Available for certain applications where permitted by the specification.

The required delivery condition should be confirmed when ordering.

ASTM A516 Grade 70 Steel Plate Applications

A516 Grade 70 is mainly used for:

Pressure vessels

Boilers

Storage tanks

Petrochemical equipment

Oil and gas equipment

Heat exchangers

Process equipment

For low-temperature service, impact testing requirements should be confirmed before ordering.

ASTM A516 Grade 70 vs Q345R

Q345R is a Chinese pressure vessel steel used for similar applications. However, A516 Grade 70 and Q345R are not directly interchangeable and should be selected according to the applicable standard and project requirements.

For export projects, the required material standard should be confirmed by the equipment designer, end user or applicable pressure vessel code.
