Grade S275N carbon steel plate sheet machinability

We also produce various sizes of section steel, the main production methods are hot rolling, cold rolling, extrusion, forging, cold drawing and so on. Profile products have complex cross-section shape and various specifications. According to the section height, it can be divided into large section steel, S275N carbon steel plate sheet, medium and small section steel, H section steel, I section steel (I-section steel), U section steel (channel steel), l section steel (angle steel) and ball flat steel, etc. Profiles are widely used in various sectors of the national economy, such as I-beam is mainly used in building components, bridge manufacturing, ship manufacturing, etc.; channel steel is mainly used in building structures, vehicle manufacturing, etc;

Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, S275N carbon steel plate sheet quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the S275N carbon steel plate sheet International leading steel materials supplier.

Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while S275N carbon steel plate sheet steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of S275N carbon steel plate sheet steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.

Vanadium element (V element) can refine grains in ordinary low carbon alloy steel, improve the strength and yield ratio and low temperature characteristics after normalizing, and improve the welding performance of steel, S275N carbon steel plate sheet included. Vanadium element (V element) is often used in combination with manganese, chromium, molybdenum, tungsten and other elements in structural steel because of its low hardenability under general heat treatment conditions. Vanadium in quenched and tempered steel is mainly to improve the strength and yield ratio of steel, refine the grain size, and pick up the overheating sensitivity.

In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service. In the process of using our steel S275N carbon steel plate sheet products, if there is any problem, just contact us in time, and our after-sales service personnel will look for countermeasures and solve the problem with you as soon as possible.
