Unlike general steel manufactures, other than regular fresh production, we also have huge stocks. What is more, we offer cutting, welding, drilling, bending, etc. deep processing for the steel materials. That enable us to meets various A514 grade E high strength steel plate steel sizes and shapes requirements of clients.So, if you have any steel demands, or steel processing needs, please do not hesitate to contact with us. We will try our best to make you stisfied.
No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than A514 grade E high strength steel plate. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel A514 grade E high strength steel plate is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.
The toughness of steel such as A514 grade E high strength steel plate is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.
The consistent tenet of honest management! Know the needs of customers, for the needs of customers, urgent customers think! Our quality is better for the A514 grade E high strength steel plate same products, our price is lower for the same quality, and our service is better for the same price. welcome to purchase steel materials from our company. we have the professional team and good after-sale system to customers. our company A514 grade E high strength steel plate is your best choose.
