SPA-H high strength weathering steel plate is widely used in the container industry because ordinary carbon steel corrodes quickly when exposed to air, which can lead to significant economic losses. SPA-H weathering steel plate ensures superior corrosion resistance compared to ordinary steel, making it ideal for long-term use.
SPA-H corten steel plate offers stable mechanical properties - including yield strength, tensile strength, and elongation - with minimal fluctuations, ensuring performance far exceeding standard requirements.
Chemical composition
| Grade | C ≤ | Mn ≤ | P | S ≤ | Si | Ni ≤ | Cr | Cu |
|---|---|---|---|---|---|---|---|---|
| SPA-H | 0.12 | 0.60 | 0.007–0.15 | 0.035 | 0.25–0.75 | 0.65 | 0.30–1.25 | 0.25–0.55 |
Our mill controls the chemical composition through advanced smelting and converter endpoint control, reducing repair times and oxygen content, stabilizing alloy element content, and improving alloy yield. This ensures SPA-H high strength weathering steel plate consistently meets or exceeds specifications.
Mechanical Properties Of SPA-H Steel Plate
| Grade | Thickness | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Bending | Inside Radius |
|---|---|---|---|---|---|---|
| SPA-H | ≤6mm | ≥355 | ≥490 | 22 | 180° | 0.5T |
| SPA-H | >6mm | ≥355 | ≥490 | 15 | 180° | 1.5T |
Lower yield strength makes forming easier. High work hardening rate ensures excellent performance during manufacturing. Surface quality and dimensional precision are strictly controlled: actual deviations are within technical requirements, with a 100% pass rate.
Hot rolling uses a coiled box system and effective descaling lines, ensuring a clean, bright surface without cracks or oxide inclusions.
Performance In Container Manufacturing
SPA-H corten steel plate hot-rolled steel plates offer consistent thickness and width, with minimal fluctuation.
Steel strips have excellent surface quality and formability, enabling one-time molding without defects such as cracks or peeling.
Customers in the container industry report high satisfaction due to the precision and reliability of SPA-H weathering steel plate in production.
We could also supply other weathering steel plates, for example, 09CuPCrNi-A, 05CuPCrNi, SPA-H corten steel plate, SPA-C, B480GNQR, Q355GNHD, Q355NHD, S355J0WP, and CORTEN-A.

What is spa H material?
As Spa-h steel coil material is a weathering steel, it forms the protective patina on the surface which gives it a rustic appearance. The chemical composition of the JIS g3125 spa-h strip includes carbon, silicon, manganese, phosphorus, sulphur, copper, chromium and nickel.
What is spa-h steel equivalent?
Worldwide equivalents of grade SPA-H (Japan: JIS ) Cross reference table for Steel SPA-H (JIS ) and its European equivalent S355J0WP (1.8945)
What is the chemical composition of SPA-H Steel?
The main elements include carbon (C), manganese (Mn), silicon (Si), chromium (Cr), and copper (Cu). Their contents are strictly controlled to ensure mechanical properties and weather resistance.
How to maintain SPA-H Steel?
SPA-H steel requires minimal maintenance. A stable rust layer protects the steel. Regular cleaning to remove dust or debris and avoiding prolonged water exposure is sufficient.
Can SPA-H Steel be welded?
Yes. Low-hydrogen arc welding or gas shielded welding is recommended. Preheating and slow cooling after welding help prevent cracking.
