Technical overview of Baosteel's BW series hot‑rolled wear‑resistant steel, including specifications, processing, and application guidance.
The BW series hot‑rolled wear‑resistant steel is a thin‑gauge (2‑12 mm) steel plate produced by Baosteel using oxygen‑converter melting, secondary refining, continuous casting, TMCP rolling, heat‑treatment and inspection. It offers high wear resistance, toughness, weldability and machinability, making it suitable for heavy‑duty equipment such as dump trucks, concrete mixers, crushers and industrial fans.
The document details manufacturing processes, delivery conditions (TMCP, quenched, quenched‑and‑tempered), mechanical and chemical properties, wear‑resistance testing methods, recommended bending, cutting and welding practices, and provides application case studies and customer service contacts. This manual is written in Chinese.
| Thickness range | 2‑12 mm |
|---|---|
| Impact energy at –40 °C (KV2) | 2.0 J |
The BW series plates are available in thicknesses from 2 mm up to 12 mm.
BW steel can be delivered in TMCP, quenched, or quenched‑and‑tempered conditions, and can be pre‑treated with blasting or painting as required.
Wear resistance is tested using a pin‑on‑disk abrasive wear test and a block‑on‑ring test (ASTM G77‑05).
