A514 Grade A, B, E, F, H, P, Q & S High Strength Steel Plate
A514 Grade A, B, E, F, H, P, Q, and S high strength steel plate is designed for structural applications requiring high yield strength and toughness under dynamic or heavy-load conditions. Unlike standard carbon plates, A514 maintains dimensional stability and resistance to deformation when subjected to repeated stress, making it suitable for crane booms, excavator arms, and heavy-duty frames. Jialu Metal stocks A514
- High yield strength and toughness for dynamic and heavy-load structural applications

- Custom dimensions available to match project-specific structural requirements
- One supplier for multiple grades and thicknesses reduces coordination across mills and inspection dates
Mill certificates issued against the ordered grade and standard. Third-party inspection available on request.
What This Material Is For
A514 Grade A, B, E, F, H, P, Q, and S high strength steel plate is designed for structural applications requiring high yield strength and toughness under dynamic or heavy-load conditions. Unlike standard carbon plates, A514 maintains dimensional stability and resistance to deformation when subjected to repeated stress, making it suitable for crane booms, excavator arms, and heavy-duty frames. Jialu Metal stocks A514 across thicknesses from 2 to 150mm, widths from 600 to 3000mm, and lengths of 6000 or 12000mm, with customization available. This allows buyers to consolidate structural plate sourcing across one supplier, one inspection, and one shipment instead of splitting orders across multiple mills.
Why Buyers Choose It
- High yield strength and toughness for dynamic and heavy-load structural applications
- Available in thicknesses from 2 to 150mm, widths from 600 to 3000mm, and standard lengths of 6000 or 12000mm
- Custom dimensions available to match project-specific structural requirements
- One supplier for multiple grades and thicknesses reduces coordination across mills and inspection dates
- Third-party inspection available on request to meet project compliance needs
Where It Is Used
- Excavator and crane booms requiring high fatigue resistance and impact strength
- Heavy-duty mining and construction equipment frames exposed to repeated stress
- Industrial machinery bases and support structures in high-load environments
- Offshore platform components and marine cranes needing high-strength, low-weight plates
- Transportation equipment such as dump truck beds and trailer frames under dynamic loading
Who It Is For
- Heavy equipment manufacturers sourcing structural plates for excavators, cranes, and loaders
- Fabricators building industrial machinery with high-stress structural components
- Contractors working on mining, oil and gas, or infrastructure projects requiring durable structural plate
- Engineering firms specifying A514 for critical load-bearing elements in design drawings
- Procurement teams managing multi-grade structural scopes who want to reduce supplier count
Problems It Solves
- Splitting structural plate orders across multiple mills due to grade and thickness limitations
- Delays caused by waiting for different mills to produce varying grades and sizes
- Inconsistent inspection schedules when sourcing from multiple suppliers
- Difficulty in matching project specifications when one mill cannot supply the full range of A514 grades
- Increased logistics complexity from multiple shipments and packaging types

- OEM service accepted for branding and marking
- Packing and shipping arrangements tailored to destination port and logistics requirements
How It Compares With The Alternatives
| Standard carbon steel plate (e.g., A36) | A514 offers significantly higher yield strength and toughness; carbon plate is cheaper but not suitable for high-stress structural applications |
|---|---|
| High-strength steel plate (e.g., A709 Grade 50) | A514 has higher yield strength and better impact resistance at low temperatures; A709 is more common in bridges and general construction |
| Alloy steel plate (e.g., 4140) | A514 is more cost-effective for structural use; 4140 is used for heat-treated components, not general structural plate |
Buying Guide
- Confirm the required grade (A514 A, B, E, etc.) based on the project’s stress and temperature conditions
- Specify thickness, width, and length in the enquiry to ensure availability
- Include impact test requirements and temperature if the application involves cold environments
- Request edge preparation and surface finish at order stage to avoid rework
- Book third-party inspection at order stage to align with project schedule
