The Baosteel B-HARD abrasion‑resistant heavy plate user manual provides specifications, processing methods, and handling guidelines for the steel product.
This manual introduces the B‑HARD abrasion‑resistant heavy plate, its grade options, chemical composition, mechanical properties, and wear‑resisting performance. It also describes the 5‑meter heavy‑plate mill, delivery conditions, and recommended processing steps such as cutting, bending, welding and heat treatment.
Technical data include maximum dimensions, surface quality limits, and typical chemical makeup. The document also lists recommended welding procedures, post‑weld heat‑treatment, and contact information for technical support. This manual is written in Chinese.
