HEB160x160x8x13 S355NL S355ML h profile steel
S355NL h beam section material
Standard: It belongs to the normalized steel in the EN 10025-3:2004 standard and is a fine-grained steel.
Chemical composition: Similar to other S355 series steels, it has a low carbon content, and elements such as chromium, nickel, and copper are added to improve corrosion resistance, and grain refinement elements such as aluminum are added.
Mechanical properties: The yield strength is usually above 355MPa, the tensile strength is between 470 and 630MPa, and the elongation after fracture is usually between 21 and 24%. In a low temperature environment of - 50℃, the impact absorption energy is not less than 27J, and it has good low-temperature toughness.
Welding performance: It has good weldability, is suitable for a variety of welding processes, and can meet the manufacturing needs of complex structures.
S355ML structural steel h beam material
Standard: Low alloy high strength structural steel produced in accordance with European standard EN 10025-4.
Chemical composition: Carbon content ≤0.20%, silicon content ≤0.50%, manganese content between 0.90 - 1.65%, phosphorus and sulfur content ≤0.035%. Alloy elements such as chromium, nickel, and molybdenum are also added to improve strength and corrosion resistance, as well as trace amounts of niobium, vanadium, and titanium to refine the grains.
Mechanical properties: Yield strength ≥355MPa at room temperature, some specifications can reach higher values, tensile strength is 470 - 630MPa, elongation ≥22% (50mm gauge length). The minimum applicable temperature is - 50℃, and good mechanical properties can still be maintained at this temperature.
Welding performance: Due to the low carbon equivalent design (CEV ≤0.45), its welded joint performance is stable and suitable for complex welded structures.
HEB160x160x8x13 h section beam means that the European standard H-shaped steel has a section height of 160mm, a flange width of 160mm, a web thickness of 8mm, and a flange thickness of 13mm. This section shape has good bending resistance and high section efficiency, which can effectively improve the load-bearing capacity and save materials. The theoretical weight per meter is about 37.7 kg.
Production process of HEB160x160x8x13 h shaped iron beam
The manufacturing process of S355NL mainly includes steelmaking, rolling and heat treatment. During the steelmaking process, the raw material composition and smelting process are controlled to obtain specific molten steel; the molten steel is cast into a billet and then hot-rolled to form the required shape and size. The process parameters are adjusted during hot rolling to obtain good organizational properties; finally, normalizing treatment is usually performed to refine the grains and further improve the strength and toughness of the steel.
HEB160x160x8x13 structural h beam advantages
