hardox 450 steel equivalent material,A572 Gr 70 , which one is better for construction?

Q690E material has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance. In addition, Hardox 450 steel equivalent material, Q690 high strength steel plate and sheet has good corrosion resistance and certain wear resistance. High strength, especially in the normalizing or normalizing plus tempering state has a higher comprehensive mechanical properties.

In today's Hardox 450 steel equivalent material steel market, most of the varieties are in excess of demand, especially after China's accession to the WTO, steel enterprises are facing increasingly fierce market competition. In order to make enterprises win a good survival and development space, operators must make effective use of Hardox 450 steel equivalent material market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.

Primary processing, steel plate cutting processing cutting method, it is a flame cutting, because it to the accuracy requirement of the cutting size is not very high, the thickness of the Hardox 450 steel equivalent material plates in a certain range can be a good cutting quality and cutting effect, and the cut surface can be very smooth, however, it is important to note that in this work, is the need to pay attention to steel plate deformation at high temperature.

A small amount of Nb is sufficient to obtain excellent comprehensive properties of Hardox 450 steel equivalent material etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.

The company conducts periodic and targeted training and guidance for after-sales service personnel. As the saying goes, "no one is perfect, no gold is red", to help after-sales service personnel improve service skills and correct service attitude. Carry out relevant technical training for after-sales service personnel, so that after-sales service practitioners have professional product knowledge.
