We manufacture carbon structural steel A514 Gr E QT steel plate plates in different sizes and of different thickness. BBNsteel has a wide range of S500MC Steel Plate manufacturers in China. Our focus is on providing customers with high-end steels that are not rolled. BBNsteel provides you with fine-grained quenched plates and tempered steel plate notable for its high strength.
Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This A514 Gr E QT steel plate alloy steel A514 Gr E QT steel plate still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.
S355J2+N steel plate belongs to the European standard low alloy structural steel grade. S355J2 steel is equivalent to Q345D grade.
