High-quality tempered wear-resistant steelDelivery standardCurrently wear resistant steel under 6 mm is mainly used in lightweight dumper carriage, the thinnest available specification is refer to 3 mm, its shape and bending property both in the domestic top level (the only cargo carriage made of wear-resistant steel with side wall and bottom plate of 3*3mm).

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 Temperature And Wear Resistant SteelAt present, common carbon steel + ceramic lining plate and other structures are generally used for high temperature and wear resistant components in domestic metallurgy, coking and other industries, with poor safety, high component weight and cost, high temperature and wear-resistant steel can effectively meet the lightweight, long 

Super Wear-Resistant SteelThe wear resistance of the wear-resistant steel is enhanced by the precipitation of superhard TiC particles. Its hardness and mechanical properties are equivalent to those of NM450, but the wear resistance is more than 1.6 times that of ordinary NM450 and more than 1.3 times that of NM550. Steel has successfully completed the task of " Industrial production of domestic extreme thin (4×2000mm) NM450SP" in the "13th Five-Year" national key research and development project.

Guocheng has produced the protective steel of FD family with tensile strength 900MPa-2000MPa andofArmaPro family with brinell hardness 440-630. With perfect bulletproof performance, cold formingand welding property, Armor plate of Guocheng steel can be widely used in some fields, such as private bulletproof vehicles, bank armored vehicles, armored personnel carriers, 

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.

High Toughness Crack-Resistant And Wear-Resistant SteelCarriage of NM450Tuf muck dump truck and NM500Tuf road transport mine dump truck.High toughness crack-resistant and wear-resistant steel NM400Tuf-NM500Tuf of LY Steel, the latest upgrade of traditional wear-resistant steel, is the best strength and toughness matching wear-resistant steel for construction machinery in the domestic market, of which the cracking and crack propagation can be effectivelyinhibited by greatly improving impact toughness under the premise of ensuring the same level of product strength and hardness unchanged.

Compared with CRIR, 304 stainless steel, high weathering steel and carbon steel imported from Japan, the corrosion resistance is excellent, and the specific data are shown in the following table:

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.

High Manganese Low-temperature Pressure Vessel SteelIn the realm of materials engineering, LGHM400 (Mn24) stands out as a beacon of excellence, boasting exceptional low-temperature resistance and wear resistance properties.

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.

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.
