Dang Steel prides itself on precise manufacturing and rigorous quality control, offering Rockstar 400 in a variety of sizes and thicknesses to cater to different industrial needs. With a focus on customer satisfaction, competitive pricing, and prompt delivery, Dang Steel has built a strong reputation throughout Vietnam and Southeast Asia as a reliable provider of durable, high-performance steel solutions.
Rockstar 400 is a robust, wear-resistant steel plate boasting a nominal hardness of 400 HBW. Its chemical makeup generally includes carbon (up to 0.30%), manganese (up to 1.70%), silicon (up to 0.70%), along with alloying elements like chromium, nickel, and boron to boost wear resistance and toughness. With a yield strength of about 1000 MPa and impressive tensile strength, it stands strong against abrasion and impact. Even with its high hardness, this steel remains easy to weld and form, making it ideal for a variety of structural and industrial applications.
