C of S275NL steel plate : is the most basic steel strengthening elements to improve the strength of S275NL steel plate

BBN steel is supplier of S275N steel plate. we have 5000 tons stock in Tianjin and Shanghai warehouse.S275N strength and toughness of ultra-fine grain structural steel plate of the present invention, by appropriately adjusting the C, Mn, Nb, V, Ti, Mo content and proportion of alloying elements, and strictly control P, S content, with the present invention production process, we can guarantee low carbon equivalent steel, high strength, high toughness and good weldability, etc., can simplify the production process and shorten the production process, reduce energy consumption, suitable for large-scale production operations. In the design, the role of the various chemical elements are:
 
C of S275N steel plate : is the most basic steel strengthening elements to improve the strength of S275N steel plate , but C affect weldability and impact toughness, considering, the carbon content to be controlled lower. 
 
Si of S275N  steel plate: is a solid solution strengthening element, to improve the strength of S275N steel plate favorable. 
 
Mn of S275N steel plate: is a solid solution strengthening element to improve the strength and toughness of tS275N steel plate are favorable. 
 
P of S275N steel plate : welding unfavorable, and has a certain cold brittleness, are harmful elements in Benxi Iron and species should be controlled as low as possible. 
 
S of S275N steel plate: easy to form MnS inclusions, with some hot shortness, are harmful elements in Benxi Iron and species should be controlled as low as possible. 
 
V, Nb, Ti of S275N steel plate: in the steel can with C, N, forming fine carbides or carbonitrides, can play the role of dispersion strengthening and grain refinement, so as to improve the strength and toughness of the steel combined effect .
