Hardox 400 plate

Hardox 400 is an abrasion-resistant (AR) wear plate with a nominal hardness of 400 HBW. Buyers must verify the Brinell hardness range (typically 370-430 HBW) and ensure the material offers excellent cold bending properties and weldability. It is crucial to request a Mill Test Certificate (MTC) according to EN 10204 3.1 to confirm the chemical composition (low Carbon, Manganese, and Chromium content) and mechanical properties.

Due to its high toughness and wear resistance, it is primarily used in mining, construction, and recycling industries. Common applications include crushers, sieves, feeders, measuring pockets, skips, cutting edges, conveyors, and excavator buckets. It is designed to perform in environments where sliding wear and impact are constant factors.

A professional supplier should provide evidence of capability in precision laser or plasma cutting, CNC bending, and drilling. Because Hardox 400 is a quenched and tempered steel, it is vital that the supplier understands heat input limits during welding to prevent softening of the material. Ask if they provide pre-fabricated parts to reduce your local processing costs.

Ensure the products comply with ISO 9001 quality management systems. While Hardox is a brand name by SSAB, many global suppliers offer equivalent AR400 grades. If you require the specific brand, verify the SSAB Hardox Wearparts membership or brand authentication. For structural safety, ensure the plates meet ASTM A514 or equivalent regional standards if used in load-bearing applications.

The most significant risk is receiving ordinary carbon steel painted to look like AR plate. Always request a third-party inspection (such as SGS or BV) to conduct a portable Brinell hardness test before the balance payment.

Steel prices are highly volatile and tied to global iron ore indices. Negotiate based on theoretical weight vs. actual scale weight to avoid discrepancies. For bulk orders exceeding 20 tons, aim for a 5-10% discount. If you are a small buyer, look for suppliers on Made-in-China.com who offer stock-holding services with MOQs as low as a single plate.

Hardox plates are heavy and prone to surface rust during long sea voyages. Insist on seaworthy packaging, including anti-rust oil coating and waterproof plastic wrapping. Ensure the supplier uses heavy-duty steel strapping and wooden dunnage to prevent shifting in the container, which can lead to maritime safety rejections or damage to the plate edges.

Check your country's specific Anti-Dumping Duties (ADD) on steel products originating from the supplier's region. Request the correct HS Code (typically 7225.40) from the supplier to calculate duties accurately. Ensure the Certificate of Origin (Form E, Form P, etc.) is provided to take advantage of any existing Free Trade Agreements (FTA).
