S690QL steel equivalent building and steel structure building

S690QL steel equivalent, NM450 wear-resistant steel plate has a Brinell hardness of 450HB. It has outstanding cold bendability and is mainly used in anti-wear conditions. NM450 wear-resistant steel plate has very good weldability. NM450 wear-resistant steel plates are used in dump truck carriages, containers, crushers, screens, feeders, feeding hoppers, elevators, blades, conveyors, buckets, blades, gears, sprockets, etc.

The effect of Q345B alloy steel plate on the mechanical properties in the annealed state. The strengthening effect of alloying elements on steel in the quenched and tempered state, because it fully utilizes all four strengthening mechanisms. Martensite is formed during quenching, and carbide is precipitated during tempering, resulting in a strong second-phase strengthening, and at the same time greatly improving the toughness. Therefore, obtaining martensite and tempering it is an economical and effective comprehensive strengthening method for steel such as S690QL steel equivalent.

Steel plate S690QL steel equivalent cutting, according to different classification standards, there are different specific types. If it is divided by cutting temperature, it can be divided into cold cutting and hot cutting. One of the cold cutting, there are water jet cutting and abrasive cutting and so on, thermal cutting is flame cutting, plasma cutting and laser cutting. In addition, we also need to know that the high-grade thick S690QL steel equivalent steel plate can be cut by flame, and its cutting is as simple as that of ordinary low-carbon and low-alloy steel, but we need to pay attention to it.

To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent S690QL steel equivalent products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the S690QL steel equivalent technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
