A516Gr70 Steel Plates for Pressure Vessel Bodies

High-strength carbon steel plates engineered for welded pressure vessels and boilers where improved notch toughness and reliable weldability are required.

Key features

• Conforms to ASTM A516 / ASME SA516 standards; Grade 60 and Grade 70 available.
• Designed for welded pressure vessel and boiler bodies; commonly specified where impact-tested material and good low-temperature toughness are required.
• Supplied in hot-rolled plate condition (standard supply practice for A516 grades). Plates up to and including 40 mm thickness are normally supplied as rolled; thicker plates or plates requiring additional notch-toughness testing are produced to order.
• Impact-tested options available to meet different service-temperature and toughness requirements.
• Mill Test Certificate (MTC) provided with material to verify chemical and mechanical properties and test results.

Why specify A516 Gr.70

• A516 Gr.70 offers higher tensile strength and improved notch toughness compared with lower grades, making it a preferred choice for pressure equipment operating at moderate temperatures.
• Widely accepted by boiler and pressure vessel manufacturers and fabricators for welded construction.

Ordering guidance

Provide the required grade, exact thickness, width, length, required impact-testing temperature (if applicable), painting/coating or surface preparation needs, and desired delivery terms so the supplier can provide an accurate quotation and lead time. Mill Test Certificate and traceability documentation are available on request.
