Q420B angle steel

Q420B angle steel has high strength and good fatigue resistance. High toughness and low ductile-brittle transition temperature, good cold forming performance and welding performance; good corrosion resistance and certain wear resistance.

As an alternative material for Q235 and Q345 angle steel, Q420 can effectively reduce the design weight of the tower by improving the material strength, thereby saving materials and reducing transportation and installation costs. effect.

Mechanical properties of Q420B angle steel:

Tensile strength σb/MPa	Yield point σs/MPa				Shock Absorption Energy (Akv(Longitudinal)/J)
520~680	Thickness/mm				+20℃
	≦16	>16 ~ 35	>35 ~ 50	>50 ~ 100
	≧420	≧400	≧380	≧360

Q420B steel is widely used in power towers, various cranes, heavy trucks, oil derricks, high temperature fans, large electric shovels, dump trucks and drilling rigs, coal mine hydraulic supports, steel structures, etc. Its tensile strength has increased.
