A572 Grade 50
ASTM A572 Grade 50 material is belong to High Tensile Low alloy steel in ASTM standard. ASTM A572 Grade 50 also can be called High Tensile Low alloy Ni-V steel. There are four steel grades or levels in the standard ASTM A572 . And they are ASTM A572 GR42(290), A572 GR50(345), A572 GR60(415), A572 GR65(450) .
Grade 50 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 50 is used in general plate applications when the plate will be riveted, bolted, or welded. Grade 50 is a Columbium-Vanadium steel that offers a minimum yield of 50,000 PSI. In addition, ASTM A572 Grade 50 is noted for its increased resistance to atmospheric corrosion. Grade 50 contains more alloying elements than plain carbon steel and thus is somewhat more difficult to form. Grade 50 is more difficult to cold work, but can be successfully bent or shaped but requires more force than plain carbon steel.
