Product information ASTM A514 grade P is a type of ASTM A514 steel. Cited properties are appropriate for the quenched and tempered condition. The graph bars on the material properties cards below compare ASTM A514 grade P to: wrought alloy steels in the same category (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it’s 50% of the highest, and so on. Steel plate A514 Grade P is under steel standard specification for high yield strength ASTM A514/A514M.A514GrP is alloy steel plate with quenching and tempering heat treatment when rolling.There are the similar steel grade as SA514 Grade P in steel standard ASME SA 514/SA 514M.When delivery steel materials ASTM A514Gr.P, steel mill would issued the original mill test certificate,also short as MTC which report the values of main chemical composition,mechanical property,all test result when rolling of steel A514 Grade P.
