20MnB5 structural alloy steel
20MnB5 steel plate

20MnB5 structural alloy steel is used for mechanical parts and all kinds of engineering components and contains one or several kinds of a certain amount of alloy element in steel.

20MnB5 Alloy structural steel is widely used in ships,vehicles,aircraft,missiles,weapons,railways,Bridges,pressure vessels and so on. 20MnB5 structural alloy steel is provided with higher yield strength,tensile strength, endurance strength,yield ratio (about 0.85 generally ) enough plasticity and toughness.
