Alloy Steel Plate

Silver Tube is a pioneer trading house of Alloy Steel Plates, in which carbon content and alloying elements influence the overall characteristics of both types of alloy steels. In these Alloy Steel Sheets, maximum attainable surface hardness depends primarily on carbon content and maximum hardness and strength in small sections increase as carbon content increases, up to about 0.7 %. Carbon contents in Alloy Steel Coils greater than 0.3 % can increase the possibility of cracking during quenching or welding. Alloying elements in these AS Sheets primarily influence hardenability, where they also influence other mechanical and fabrication properties including toughness and machinability. AS Plates are often specified when high strength is needed in moderate-to-large sections. hether tensile or yield strength is the basis of design, thermally treated AS Coils generally offer high strength-to-weight ratios. The low carbon in these Alloy Steel Sheets Plates provides resistance to sensitization during welding and other thermal processes.

Alloy Steel Plates Sheets does not perform well in chloride solutions, even in small concentrations, or in sulphuric acid. At large, wear resistance can be of better-quality by growing the rigidity of Alloy Steel Sheets Coils, by stipulating an alloy by means of better carbon content (deprived of increasing stiffness), or by both. For any combination of Alloy Steel Plates Coils and heat treatment, three factors tend to decrease toughness: low service temperature, high loading rates, and stress concentrations or residual stress. We also offer our products at customized sizes and shapes to our clients.
