Q550NH Steel
Q550NH is a high-tension weathering steel known for its impressive mechanical properties. Q550NH steel has a yield strength of over 550 MPa and a tensile strength ranging from 620 to 780 MPa. These qualities make it exceptionally strong and suitable for various demanding applications.
To enhance the properties of Q550NH steel, specific alloy elements are added selectively. These include Niobium (Nb) in the range of 0.015-0.060%, Vanadium (V) between 0.02-0.12%, Titanium (Ti) from 0.02-0.10%, and Aluminum (Alt) with a minimum of 0.020%. The total content of Nb, V, and Ti combined should not exceed 0.22%.
These additions improve the steel’s strength, toughness, and resistance to atmospheric corrosion, making Q550NH an ideal choice for structures exposed to harsh weather conditions. Its high yield and tensile strengths ensure durability and longevity in various industrial applications.

Q550NH Steel Specifications
Q550NH steel is a type of weather-resistant steel that is designed to resist atmospheric corrosion and provide high strength and good toughness. It is used in various applications such as bridges, buildings, and other structures that are exposed to harsh weather conditions.
The steel contains alloy elements such as copper, nickel, chromium, and phosphorus, which contribute to its corrosion resistance properties. The presence of these elements forms a protective layer on the surface of the steel when exposed to the atmosphere, which helps to prevent further corrosion.
Q550NH steel has a minimum yield strength of 550 MPa and a minimum tensile strength of 620 MPa, making it a strong and durable material for structural applications. It is typically supplied in a normalized or controlled rolled condition, which improves its toughness and ductility.
In addition to its use in structural applications, Q550NH steel is also used in the manufacture of containers, railway rolling stock, and other outdoor equipment that requires high strength and good corrosion resistance.
