1)Material: S460ML, S460QL, S460J0, S690QL1, S890QL1, S960QL1, A514GrQ, etc.
2)Packing: standard sea-worthy packing
3)Surface treatment: punched, welded, painted or as per customer’s requirement
4)Size: according to customers’ requirement
According to the strength, it can be divided into high-strength steel and ultra-high-strength steel.
1. Divided by tensile strength:
High-strength steel: TS≥340MPa (cold rolling); TS≥370MPa (hot rolling and pickling)
Ultra-high strength steel: TS>590MPa
2. Divided by yield strength:
High-strength steel: YS≥210MPa
Ultra-high strength steel: YS>550MP
1)With the development of metallurgical technology, the cost of high-strength steel has been continuously reduced
2)Optimized from the body structure, reducing various reinforcement plates and reinforcing plates
The weight of the vehicle is reduced, and the number of welding points is reduced at the same time, which not only improves performance but also reduces less energy consumption
3)Improved safety performance
Therefore, it has become an irreversible trend for automotive materials to develop towards high-strength steel plates. With the advent of the era of low-carbon economy, the automotive and transportation industries have been criticized at the climate conference. Reducing vehicle weight can effectively reduce fuel consumption and reduce carbon emissions. Therefore, the lightweight of automobiles has become the main development direction of the automobile manufacturing industry.
Low-alloy ultra-high-strength steel is mainly used in high-pressure vessels, bulletproof armor materials, important structural parts, pressure-resistant shells, conventional weapons, petrochemical, wind power industry, nuclear power industry and automobile industry. Its wide application range is closely related to its high strength, and corresponding products should be selected according to the special requirements of the industry to reflect the best value.
High-alloy ultra-high-strength steel has strong toughness and is mainly used in pressure shells, stressed structures, armor plates, and high-pressure vessels.
Ultra-high-strength bulletproof steel plates are mainly used for super-functional products such as bulletproof vests, helmets, and cash transport vehicles. Good stability and high bulletproof performance are the main popular factors.
Maraging steel has high purity, high strength, good plasticity and toughness, especially high yield strength and fracture toughness. For the manufacture of large brackets, parts, pressure housings, power transmission shafts, high pressure vessels, moulds, springs and deep drawn parts.
