Description
Product Application
The standard of S550QL1 high-strength steel is EN 10025-6, with a specific chemical composition range of carbon (C) ≤ 0.22, silicon (Si) ≤ 0.55, manganese (Mn) ≤ 1.70, phosphorus (P) ≤ 0.025, sulfur (S) ≤ 0.015, chromium (Cr) ≤ 0.90, nickel (Ni) ≤ 1.20, copper (Cu) ≤ 0.50, molybdenum (Mo) ≤ 0.15, aluminum (Al) ≤ 0.020, titanium (Ti) ≤ 0.020, niobium (Nb) ≤ 0.050, and vanadium (V) ≤ 0.12.
The tensile strength range of S550QL1 high-strength steel is between 630-780MPa, and the minimum yield strength is 550MPa. The minimum elongation at fracture is 13%.
S550QL1 high-strength steel is commonly used in construction, bridges, vehicles, machinery, and shipbuilding. It is usually in a hot-rolled controlled rolling state.
The advantages of this type of steel include high strength and hardness, good toughness and ductility, and corrosion resistance. This makes it able to withstand large forces and stresses, and maintain stable performance under extreme conditions.
However, the disadvantages of S550QL1 high-strength steel are its higher cost and the relatively high processing requirements, which requires the use of specialized equipment and processes.
The most common forms of S550QL1 high-strength steel include plate, strip, and profiled steel. There are comparable grades among different countries, such as BS 55F, ASTM A517 Gr.Q, JIS S690QL, ISO 4952 FeE690VKT, NBN 629 E, UNI FeE690VKT, etc.
In summary, S550QL1 high-strength steel has high strength and good toughness, and is widely used in construction and heavy machinery manufacturing fields. However, its higher cost and processing requirements need specialized equipment and processes.
