A455 / A516 Grade 70 carbon steel plate supplied in the as-rolled condition with semi-killed or capped deoxidation. These hot‑rolled pressure‑vessel plates are intended for boiler and related low- to moderate-temperature applications where good weldability, adequate notch toughness and reliable formability are required.
Key features
- Material: A455 (commonly specified as equivalent to ASTM A516 Grade 70 for boiler/pressure‑vessel use)
- Delivery condition: as‑rolled; semi‑killed or capped deoxidation
- Mechanical behavior: engineered for good weldability and notch toughness for pressure‑containing service
- Typical uses: boilers, pressure vessels, storage tanks and other welded fabrications exposed to moderate temperatures
- Supply options: available from stock in a range of plate thicknesses and widths; can be cut, slit or prepared to customer size and edge requirements on request
- Quality documentation: mill test certificates and standard chemical/mechanical test reports available upon request
Why specify these plates
A455/A516 Grade 70 plates are widely used where a balance of strength, toughness and weldability is needed for pressure equipment. The as‑rolled, semi‑killed/capped condition supports consistent performance during fabrication (welding/forming) and in-service operation. Stock availability and cut-to-size services reduce lead time for fabricators and boiler manufacturers.
For ordering, specify required thickness, width, edge condition, any heat or mechanical test requirements, and whether mill test certificates or third‑party inspection are needed.
