LGNHP800 is about 25% lighter than traditional materials when used to manufacture photovoltaic supports. At the same time, it can be used exposed without coating under C3 environment, and the thickness reduction is less than 0.1mm/a in 30 years.

Heat resistant steel of high chrome alloy steel.The products of Guocheng have been applied on a large scale. SA387GR91CL2, commonly referred to as P91, is a high-performance steel known for its exceptional properties, making it an ideal choice for demanding applications. This steel exhibits superior oxidation resistance, allowing it to withstand harsh environments where other materials might degrade.

Ferritic stainless steel of high chrome alloy steel.The recently developed T4003 ferritic stainless steel exhibits a remarkable combination of properties, making it an ideal choice for various applications. This steel boasts excellent strength, ensuring it can withstand significant mechanical stress. Its superior corrosion resistance protects it from rust and degradation, even in harsh environments, thereby enhancing its durability.

High Manganese Wear-resistant SteelHigh manganese austenitic steel, exemplified by Mn13 and X120Mn12, showcases exceptional toughness and impressive surface work hardening properties. When subjected to intense impact or extrusion loads, the surface of the steel undergoes work hardening, resulting in a substantial increase in surface hardness from the initial HB200 to an impressive HB750. Remarkably, the core of the steel plate retains its excellent impact toughness throughout this process.

Corrosion-Resistant And Wear-Resistant SteelThe corrosion and wear resistant steel developed by Steel is mainly used in sanitation trucks, dredging projects, dredging pipelines and other industries. When corrosion wear occurs, the wear property of materials is affected by corrosion resistance, and the problem of poor wear property cannot be effectively solved by simply increasing hardness.

High Nickel Low Temperature SteelLow-temperature Nickel steel, with its exceptional properties, serves a vital role in the storage, treatment, and transportation of a variety of liquid gases such as ethylene, methane, liquefied natural gas, oxygen, and nitrogen. Among the array of storage tank devices and pipelines designed for this purpose, the 06Ni9DR steel plate stands out for having obtained the prestigious certification from the ABS classification society.

Engineering machinery steel of LY Steel has high strength, good forming property, excellent surface quality, high thickness accuracy and good weldability with yield strength of 460~1400MPa and thickness of 2.0~25.4mm, which is widely used in machinery, coal, transportation and mining and all kinds of engineering construction and other required equipment, such as drilling machine, electric furnace, electric wheel dump, excavator, loader, bulldozer, hydraulic aerial cage, all kinds of lifting equipment and coal mine hydraulic support and other mechanical equipment.Delivery standradTechnical par
