China has globally debuted and successfully delivered the 1.5mm ultra-thin heat-treated wear-resistant steel grade BW450, marking a world-first breakthrough in the field of ultra-thick (ultra-thin) high-performance wear plate manufacturing.

 

Developed and produced by Baoshan Iron & Steel Co., Ltd. (Baosteel), this product fills a critical industry gap. It achieves an unprecedented combination of extreme thinness (1.5mm), high flatness, excellent surface quality, and HB450-level hardness through advanced hot-rolling and precise heat-treatment processes. The successful commercial delivery provides a key material solution for the lightweighting of construction machinery and mining dump trucks.

Thin as paper, yet hard as armor. In response to the extreme technical requirements of BW450, including superior flatness, premium surface quality, ultra-thin gauge and high hardness, Baosteel's hot rolling and heat treatment team conducted full-process precise optimization covering contract confirmation, product design, rolling, heat treatment and cutting. Through systematic collaboration and efficient linkage, they overcame multiple technical bottlenecks, achieved the high-standard extreme manufacturing, and realized stable product delivery.

 

GNEE STEEL has long maintained close strategic cooperation with Baosteel. We keep deep communication on new product R&D, technical indicators and supply stability, and continuously provide customers with high-quality, cost-effective domestic high-end wear-resistant steel materials.
