Q960D quenched and tempered high-strength steel is used to make pressure shell parts, deep tide lifesavers, high-pressure structural parts, aerospace equipment, armored vehicles, and manufacturing various engineering machinery, such as drilling rigs, electric shovel, and Electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment and wear-resistant structural parts.

The company selects steel raw materials and controls every quality link from the source to ensure high quality. Each process is strictly checked to ensure that there is zero failure rate in the customer's on-site use. Provide customers with high-quality SPA-H marking products and services with an innovative spirit and work together with customers to create a better future. The company can process and cut various special-shaped parts according to customer needs, and can also customize futures of various material specifications according to requirements.

SPA-H marking, Q345B steel plate strength has much to do with its thickness. First, the min. yield strength of Q345B steel plate: 345 Mpa for thickness ≤16mm, 335 Mpa for thickness 16-40mm, 325 Mpa for thickness 40-63mm, 315 Mpa for thickness 63-80mm, 305 Mpa for thickness 80-100mm, 285 Mpa for thickness 100-150mm, 275 Mpa for thickness 150-200mm, 265 Mpa for thickness 200-250mm. Second, the tensile strength of Q345B steel plate: 470-630 Mpa for thickness ≤100mm, 450-600 Mpa for thickness 100-250mm.

Steel logistics takes “steel” as the carrier, “logistics” as the operation, and “information” as the core. It integrates steel trade, e-commerce, and tripartite logistics as one. The flow of funds, information, and logistics promote each other and integrate with each other. Construction industry, metallurgy industry, information industry, modern logistics cross-industry.
