Q355GNH weathering steel plate

Q355GNH weathering steel plate is a high-strength atmospheric corrosion resistant steel, which belongs to the low alloy steel series, between ordinary carbon steel and stainless steel. This steel improves its atmospheric corrosion resistance by adding a small amount of corrosion resistant elements such as copper (Cu) and nickel (Ni). The weather resistance of Q355GNH is 2 to 8 times that of ordinary carbon steel, and the paintability is 1.5 to 10 times that of ordinary carbon steel. It has the characteristics of toughness, plasticity, forming, welding, abrasion, high temperature resistance and fatigue resistance.

PRODUCT DETAILS

Mechanical properties: Yield strength: ≥355MPa; Tensile strength: 490 - 630MPa; Elongation: ≥22%
Features: Good atmospheric corrosion resistance: By adding corrosion-resistant elements such as copper and nickel, a protective layer is formed on the surface of the metal matrix, and its weather resistance is 2 - 8 times that of ordinary carbon steel.
Excellent comprehensive mechanical properties: It has high strength and certain toughness.
The material can be recycled and is low-carbon and environmentally friendly.
Steel parts are corrosion-resistant and life-extending, thinning and consumption-reducing, saving labor and energy.
Green and environmentally friendly, no initial coating is required, and the use of fire-retardant coatings and fire-retardant coatings can be reduced, thereby reducing pollution, shortening construction period, reducing costs and reducing maintenance.
Application areas: Mainly used for steel structures such as railways, vehicles, bridges, towers, etc. that are exposed to the atmosphere for a long time. Commonly used in the manufacture of containers, railway vehicles, oil derricks, port buildings, oil production platforms, and chemical petroleum equipment containing hydrogen sulfide corrosive media and other structural parts.
