ABS class shipbuilding steel plate contains two kinds as common strength and high strength ship plate according to different yield and tensile strength.Common strength shipbuilding plates Grade A, B, D, E and F are mainly used to contribute hull of ship,and high strength shipbuilding plate are mainly built the cranes of bulk and breaker ships in low temperature surroundings. ABS Grade AH36, DH36, S700MC steel for cranes structure, and EH36 plate rolling specifications range:Thickness within 3-300mm,Width within 1250-4000mm.

Advantages of S700MC steel for cranes structure, stainless steel: 1. Chemical properties: the chemical and electrochemical corrosion resistance of stainless steel is the best in steel, second only to titanium alloy. 2. Physical properties: stainless steel has good heat resistance, high temperature resistance, low temperature resistance and even ultra-low temperature resistance. Stainless steel can work safely at - 270℃ - 400℃ for a long time. No matter at high or low temperature, no harmful substances will be precipitated, and the stainless steel material properties are quite stable.

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium S700MC steel for cranes structure carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some S700MC steel for cranes structure alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.
