General Product Description

BS 1300 D/E represents the pinnacle of ultra-high-strength structural steel, boasting a minimum yield strength of 1300 MPa. It's engineered to cater to applications where load-carrying structures demand the utmost in strength while minimizing weight.

Baosteel's innovation in developing BS 1300 D/E aims to create the most lightweight steel solutions possible or to serve as a viable alternative to other materials.

The benefits of BS 1300 D/E are as follows:

It offers exceptional bendability and maintains a superior surface quality.
It is highly weldable, with the heat-affected zone (HAZ) exhibiting outstanding strength and toughness.
The steel's uniformity is exceptional, ensured by stringent tolerances across the plate.
It features high impact toughness, providing robust resistance to fractures.
