1.8 For structural products cut from coiled product, the Grades 42 , 50 , and 55  are intended for additional requirements, including additional testing require- riveted, bolted, or welded structures. Chemical Composition conform to the tensile properties given in Table 4. Type S81.1 For Grade 50  steel of A572 Grade 345 steel plate -- Shanghai Royal IndustryDelivery Status :Rolling, rolling or normalizing probe. ASTM A572 Grade 345 Low alloy high strength steel application :A572 Grade 345 steel is widely used in engineering structures, such as building steel, construction machinery, mining machinery, trucks, bridges, pressure vessels, especially for welding and toughness requirements of the construction and engineering machinery part.
A572 Grade 55 is in the American standard ASME SA572. A572 Grade 55 material is belong to High Tensile Low alloy steel . A572 Grade 55 also can be called High Tensile Low alloy Ni-V steel.A572 Grade 55 is mainly used in engineering structures,such as construction structure steel,construction machinery, mining machinery, heavy trucks and pressure vessels, etc..

Please inquire for grades not listed above or for custom designed grades. Hot-Rolled cut lengths are available between 16 and 40 feet. Steel
coupons were cut from A572 Gr. 50 steel sheets. The chemical composition of A572 steel is different from that of conventional A36 steels. The chemical compo-sition of both types of steel, together with actual composition ofA572 steel used in current test program (as specied by the manufacturer) is tabulated in Table 1. Hot Rolled Steel Plate ASTM A572 Grade 50 Manufacturer ASTM A572 Carbon Steel Plate. ASTM A572 Specification refers to High-Strength Low-Alloy Steel Plate for structural building, among the 5 steel grades of 42, 50, 55, 60 and 65, Grade 50 is one most common steel in applications where need more strength and less weight, use steel plate of this grade other than ordinary carbon steel will make the steel structure with same steel strength but Plate - McneilusASTM A572 Gr50. ASTM A572 is a high strength low alloy steel that offers a higher strength than plain carbon steel plates plus ductility, weldability, formability, toughness and fatigue strength. A572 meets a minimum strength requirement (dependent on grade) and provides good workability and
