Hemaokang Steel (Shandong) Co., Ltd. is proud to offer high-quality Carbon Steel Plate A516 Gr 60 & Gr 70 in thicknesses of 10mm, 12mm, and 15mm, with dimensions of 2000x6000mm. As a reliable supplier with an annual export value of US$50–100 million and ISO9001 certification, we ensure every plate meets the rigorous demands of pressure vessel manufacturing. Our plates come with a complete Mill Test Report (MTR) for full traceability, giving you confidence in material performance and safety.
These plates are manufactured in strict accordance with ASTM A516/A516M standard, which is the industry benchmark for carbon steel plates used in pressure vessels and boilers. The combination of controlled chemistry, uniform mechanical properties, and precise dimensional accuracy makes them ideal for welding, forming, and critical service environments.
Key Features & Technical Specifications
- Grade Options: A516 Gr 60 (minimum yield 60 ksi) and A516 Gr 70 (minimum yield 70 ksi) – choose based on design pressure requirements.
- Thickness Range: Available in 10mm, 12mm, and 15mm – suitable for medium to heavy pressure vessel shells, heads, and flanges.
- Standard Size: 2000mm width × 6000mm length – optimized for common fabrication layouts, reducing waste and welding joints.
- Mill Test Report: Each plate is supplied with an MTR that lists chemical composition, tensile strength, elongation, and impact test results (upon request).
- Weldability: Excellent low-carbon content and controlled residual elements ensure good weldability without preheating for most applications.
- Surface Finish: As-rolled surface is standard; blast & prime or shot blasting is available as an option.
- Customization: Additional heat treatment (normalizing, stress relieving) and cutting to non-standard sizes are available upon request.

Frequently Asked Questions
-
What is the difference between A516 Gr 60 and Gr 70?
Gr 60 has a minimum yield strength of 60 ksi (415 MPa) and Gr 70 has 70 ksi (485 MPa). Gr 70 is used for higher design pressures, while Gr 60 is suitable for moderate applications. Both have excellent weldability and toughness. -
Do you provide the Mill Test Report for every plate?
Yes, a Mill Test Report (MTR) is included with each order, showing the chemical composition, tensile, yield, and elongation results. Impact test reports can be added upon request. -
Can these plates be used for high-temperature service?
A516 plates are designed for moderate and lower temperature service. For high-temperature applications, other grades like A387 or A204 may be more suitable. Please consult our technical team for specific requirements. -
What are the standard tolerances on thickness and flatness?
Thickness tolerances follow ASTM A516/A516M, typically ±0.010" for 10–15mm plates. Flatness tolerances are also per ASTM. We can provide cut-to-size plates with tighter tolerances upon request. -
Do you offer cutting services (plasma, laser, or shearing)?
Yes, we offer custom cutting to your required dimensions. Please specify the exact size and quantity when requesting a quote. -
What is the minimum order quantity (MOQ)?
Our MOQ is typically 1 ton for standard sizes, but we can accommodate smaller quantities for sample orders. Contact us for details. -
How long does delivery take?
For stock items (10mm, 12mm, 15mm × 2000×6000mm), delivery is usually 7–15 days after order confirmation. Larger volumes or custom sizes may require 20–30 days. -
Is the plate surface treated for rust prevention?
Standard plates are shipped as-rolled. We can apply anti-rust oil or primer coating as an optional service. Please specify your preference.
