What This Material Is For
ASTM A516 Grade 70, 65, 60 and 55 steel plates are designed for pressure vessel and boiler service at moderate temperatures. These plates are supplied in thicknesses from 2 to 150mm, widths from 600 to 3000mm, and lengths of 6000 or 12000mm, with customization available. Jialu Metal holds these grades in stock across multiple thicknesses and dimensions, so a project requiring different grades within the same vessel or boiler does not need to be split across multiple mills or inspection cycles. All plates are available in standard and custom sizes, with consistent mill certification and export readiness.
Why Buyers Choose It

Where It Is Used
- Boiler drums and pressure vessels in power generation and industrial steam systems using A516 Grade 70 and 65 for high-pressure service
- Storage tanks and process vessels in petrochemical and chemical plants where A516 Grade 60 and 55 meet moderate pressure and temperature demands
- Pressure vessel fabrication in oil and gas processing where code compliance to ASTM A516 is required
- Marine and offshore equipment components where A516 plates are used in non-cryogenic pressure containment
- Industrial heat exchangers and separators where A516 Grade 60 or 55 is selected for cost-effective performance
Who It Is For

- Boiler manufacturers needing A516 Grade 70 and 65 for high-pressure drums and headers
- EPC contractors managing boiler and vessel scopes across multiple projects
- Fabrication shops requiring consistent material certification and delivery across mixed-grade orders
- Procurement engineers who need one supplier for A516 plates across different thicknesses and dimensions
Problems It Solves
- Splitting a pressure vessel scope across multiple mills due to grade or thickness availability gaps
- Delays caused by waiting for a single mill to produce a specific thickness or grade within a project window
- Inconsistent mill certificates when sourcing from multiple suppliers for a single vessel
- Multiple inspection visits and shipment dates when grades are sourced from different mills
- Lack of customization options for non-standard thicknesses or widths in standard stock lists

| Surface Finish | Mill finish, with options for shot blasting or cleaning upon request |
| Testing | Chemical composition and mechanical property tests per ASTM A516 |
| Certification | Mill certificate issued per ordered grade and standard |
Materials
- Carbon steel plates with controlled chemical composition for toughness and weldability at moderate temperatures
- A516 Grade 70 for high-strength, high-pressure applications in boilers and pressure vessels
- A516 Grade 65 for service at elevated temperatures with good creep resistance
- A516 Grade 60 and 55 for lower-pressure systems where cost and availability are key factors
- Material suitable for welding, forming, and machining in standard fabrication processes
Manufacturing Route
Quality Control
- Chemical composition tested against ASTM A516 requirements for each heat
- Mechanical property tests including tensile, yield, elongation and impact testing
- In-house CNAS-certified laboratory conducts routine testing and holds traceable records
- Mill certificates issued for each batch, including test results and compliance statements
- Third-party inspection available on request, bookable at order stage
Customisation Options
- Custom thickness, width and length available upon request

- OEM service accepted for branding, marking and packaging
- Packing tailored to destination port, shipping method and inspection regime
- Surface treatment options such as shot blasting or cleaning available
How It Compares With The Alternatives
| A36 steel plate | A36 is cheaper and widely available but lacks the toughness and weldability required for pressure vessel service; A516 is the correct choice for code-stamped vessels |
|---|---|
| A537 Class 1 plate | A537 Class 1 is used for higher-pressure service and requires more stringent testing; A516 is sufficient for moderate-pressure vessels and more cost-effective |
| A285 Grade C plate | A285 Grade C is lower strength and not suitable for high-pressure applications; A516 offers higher strength and better toughness at moderate temperatures |
Buying Guide
- Start with the design pressure and temperature of the vessel to select the appropriate A516 grade
- Confirm required thickness and dimensions early, as availability varies by size and grade
- Specify the heat treatment condition (normalized) if required for weldability or code compliance
- Include the thickness and width in the enquiry to avoid delays due to stock availability
- Request mill certificates and third-party inspection at order stage to align with project schedules
Questions About A516 Grade 70, 65, 60, 55 Boiler Pressure Vessel Steel Plate
Which A516 grades do you supply?
We supply A516 Grade 70, 65, 60, and 55, with customization available for other grades upon request.
What thicknesses and dimensions are available?
