Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of S700MC hot rolled steel for car gear circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and S700MC hot rolled steel for car gear management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.

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 hot rolled steel for car gear, and EH36 plate rolling specifications range:Thickness within 3-300mm,Width within 1250-4000mm.

We have 4 typical production lines S700MC hot rolled steel for car gear, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. The Seamless pipe production line range is OD 10.3mm-965.2mm, wall thickness 1.0mm-60mm, Annual capacity is 500 thousand tons. LSAW pipe production line range is OD 406mm-1524mm, wall thickness 6mm-50mm, Annual capacity is 150 thousand tons.

The effect of nitrogen (N) on the properties of S700MC hot rolled steel for car gear and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in S700MC hot rolled steel for car gear and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
