ASTM A514 is a USA-standard high-yield quenched and tempered steel plate developed for structural applications where high strength and durability are critical. With yield strengths ranging from 100 ksi (690 MPa) to 130 ksi (900 MPa) depending on the grade, A514 plates are engineered for rigid, load-bearing, and fatigue-prone environments.
Commonly known as T-1 Steel, A514 is widely used in cranes, heavy equipment, trailers, bridges, and pressure vessels. It offers excellent weldability, high impact resistance at low temperatures, and dimensional stability even under extreme conditions.
Hindustan Steel Corporation supplies ASTM A514 Plates in India, available in various grades like A514 Grade B, E, F, and Q — all with full MTC, cut-to-size service, and export support.
ASTM A514 steel plates are chosen by engineers and OEMs for their strength, formability, and performance under dynamic load conditions:
Its consistent strength-to-thickness performance allows designers to reduce material usage and increase payload efficiency.
The mechanical values of ASTM A514 depend on the specific grade (such as B, Q, F), but typically fall in the following range:
| Property | Typical Value |
|---|---|
| Yield Strength | 690 MPa to 900 MPa (100–130 ksi) |
| Tensile Strength | 760–1000 MPa |
| Elongation | ≥18% (for thinner plates) |
| Impact Energy (Charpy V) | ≥20 ft-lbs at –46°C (Grade Q) |
| Hardness (Brinell) | 235–290 HB |
A514 maintains structural integrity even under vibration, dynamic loads, and cold climates.
The alloy composition of ASTM A514 provides its strength, toughness, and weldability:
| Element | Typical % Range |
|---|---|
| Carbon (C) | 0.12 – 0.21 |
| Manganese (Mn) | 0.90 – 1.35 |
| Chromium (Cr) | 0.40 – 0.60 |
| Nickel (Ni) | 0.40 – 0.70 |
| Molybdenum (Mo) | 0.15 – 0.30 |
| Phosphorus (P) | ≤ 0.025 |
| Sulphur (S) | ≤ 0.025 |
| Silicon (Si) | 0.20 – 0.35 |
| CE (Carbon Equivalent) | ~0.45–0.50 |
Excellent for welding with low-hydrogen consumables and controlled heat input
ASTM A514 is a U.S. standard steel plate, widely accepted for heavy structural and mechanical use.
Equivalent or Comparable Grades:
| Standard / Brand | Grade |
|---|---|
| ASTM A514 | Grades B, E, F, H, Q, S |
| ASTM A517 | Pressure vessel equivalent |
| EN 10025-6 | S690QL, S890QL (approx. strength) |
| SSAB | T-1 Steel / A514 (trademarked) |
| Dillinger | Dillimax 690T / 890T (similar) |
Mechanical equivalence may align, but chemical and processing differences should be verified before substitution.
At Hindustan Steel Corporation, we supply cut-to-size and full sheets of ASTM A514 steel plates, suited for fabrication, machining, or export.
Available Dimensions
We also offer custom waterjet/plasma cutting and drilled hole profiles.
ASTM A514 is supplied in the quenched and tempered (Q&T) condition
This heat treatment process delivers consistent strength across the plate and reliable performance in high-stress applications.
A514 plates are fabricator-friendly but demand adherence to high-strength steel guidelines.
Welding:
Machining:
Cutting:
We offer technical support and welding advice for first-time fabricators of A514.
We’re one of the few suppliers in India who stock ASTM A514 Grades B, Q, and F with:
“From bridges to boom arms, we deliver U.S. standard high-strength plates — fast, certified, and cut-to-spec.”
If you’re evaluating other high-yield options, we also supply:
We supply ASTM A514 plates from India to global markets, especially where U.S.-standard steels are required for structural, military, or heavy equipment projects.
Export Reach:
Export Packaging:
We support TPI inspection (SGS, BV, Lloyds) for project supply or government approvals.
Here’s when to choose ASTM A514 plates over other grades:
Let us know your drawing/spec, and we’ll match the ideal A514 grade.
We supply ASTM A514 plates with all mandatory and optional test documentation:
Delivered With:
Every plate is traceable by heat number and batch stamping.
A514 is used for structural components, while A517 is designed for pressure vessel applications, both with similar strength levels.
Grade Q is ideal for high-impact environments like crane booms, bridges, and offshore rigs — it has guaranteed impact resistance at –46°C.
Yes, they are mechanically comparable. However, chemical specs and standards differ (ASTM vs EN), so substitution must be validated.
It typically ranges from 235 to 290 Brinell hardness (HB) depending on grade and thickness.
Yes, Hindustan Steel Corporation supplies A514 Grade B, Q, and F from our Mumbai and Taloja stockyards.
Prices vary by grade, thickness, and size — contact us for the latest ₹/kg or CIF rate
Yes. All our plates come with MTC, and we provide Charpy impact test results for Grade Q.
Yes. We offer inspection from SGS, BV, Lloyds, or your preferred agency.
Absolutely. We export globally with full documentation and seaworthy packaging.
Grade Q or Grade F — both offer high impact resistance and strength, ideal for booms and lift arms.
Yes, but use low-hydrogen welding methods and preheat for thick sections.
100 ksi, or approximately 690 MPa.
Yes. It can be flame, plasma, or laser cut — follow best practices to control heat input.
