In the Chinese market for early 2026, the price of AH36 steel plate typically ranges from USD $450 to $800 per metric ton. Pricing is heavily influenced by thickness, certification (e.g., CCS, ABS, BV), and order volume.
Price Breakdown by Specification (Estimated)
| Thickness | Estimated Price (USD/Ton) | Notes |
|---|---|---|
| Thin Plate (approx. 6mm) | $655 – $770 | Higher processing costs per ton. |
| Medium Plate (10mm - 14mm) | $710 – $730 | Most common structural standard. |
| Thick Plate (24mm+ / Bulk) | $500 – $710 | Significant discounts for orders over 50–100 tons. |
Key Market Factors for 2026
Bulk Discounts: Large industrial orders (25+ tons) can lower the price to between $500 and $600 per ton.
Certifications: Plates certified by major marine classification societies like the American Bureau of Shipping (ABS) or China Classification Society (CCS) may carry a premium compared to generic mild steel.
Supplier Platforms: For current real-time quotes, professionals often use b2b platforms such as Alibaba's AH36 section or Made-in-China to compare factory-direct offers.
Comparison: Chinese factory-direct pricing remains highly competitive, often $100–$200 cheaper per ton than equivalent US or European domestic supplies.

What is the difference between AH36 and DH36 steel?
Certified by the American Bureau of Shipbuilding (ABS) and Bureau Veritas (BV). AH36 material is a kind of normal temperature steel, and DH36 steel is a kind of low temperature steel. Shipping steel plate, manufactured in regard of classification society, is widely used in building ship structure.
What is the difference between A36 and AH36 steel?
In this condition, ASTM AH36 steel and A36 steel is totally the same. However, at most times, ASTM A36 steel means another steel type, it is A36 mild steel. A36 mild steel is for general construction, seldom used for ship building. A36 mild steel strength is lower than ASTM AH36 shipbuilding steel strength.
What is the yield strength of AH36 steel?
51,000 psi
Marine & Offshore Steel Plate
ABS AH36: Has a minimum yield strength of 51,000 psi (355 MPa) and a minimum tensile strength of 71,000 – 90,000 psi (490-620 MPa).
What is the meaning of AH36?
AH36 is a high-strength shipbuilding steel used worldwide. It meets the ASTM A131/A131M standard. The "A" stands for the shipbuilding grade, "H" indicates high strength, and "36" represents the minimum yield strength of 36,000 psi. Equivalent grades include ABS AH36 and LR AH36.
What is the tensile strength of AH36?
AH 36 plate is a high-strength shipbuilding steel used to construct ships and other marine structures. It has a minimum yield strength of 355MPa and an ultimate tensile strength of 490-620MPa.
