A529 grade 50 STEEL PLATE

A529 Grade 50 Steel plate also called as A529 Grade 345,its minimum yield strength shall be above 345 Mpa,normally A529 Grade 50 steel plate is equal to A572 Grade 50 steel plate when room temperature,but A529 Grade 50 normally requires low temperature impacting test when ordering,so A529 Grade 50 can be impacted with 0 Degree centigrade,-20 Degree centigrade and -40 Degree centigrade,in this case,A529 Grade 50 can be the same as S355J2 steel plate or S355J0 steel plate in European standard EN 10025-2.
