A572 Grade 345 is a high strength, low alloy steel that finds its best application where there is need for more strength per unit of weight. Less of this material is needed to fulfill given strength requirements than is necessary with regular carbon steels. Grade 345 is used in general plate applications when the plate will be riveted, bolted, or welded. Grade 345 is a Columbium-Vanadium steel that offers a minimum yield of 50,000 PSI. In addition,ASTM A572 Grade 345 is noted for its increased resistance to atmospheric corrosion. Grade 345 contains more alloying elements than plain carbon steel and thus is somewhat more difficult to form. Grade 345 is more difficult to cold work, but can be successfully bent or shaped but requires more force than plaincarbon steel. Standard : ASTM A572/A572M
Dimension range : 1.2mm -680mm x 1000mm-4000mm x 1000mm-18000mm
