sa573 gr 58 structural steel carbon plate 10mm

We received new order from Myanmar's Navy. It is about sa573 gr 58 structural steel carbon plate AH36 marine grade steel plates, which will be used to build ships. This is the third time we supplied marine grade steel materials for Myanmar's Navy. This time a new delegation team came to visit us and spoke highly about our production lines and our marine grade steel plates performance supplied sa573 gr 58 structural steel carbon plate to Myanmar's Navy before. Both of us expects a pleasant cooperation.

Low alloy high strength steel plate is made by adding a small amount of alloy elements on the basis of carbon structural steel (carbon content 0.16% ~ 0.2%). sa573 gr 58 structural steel carbon plate, Low alloy high strength steel plate has good welding performance, plasticity, toughness and processing technology, good corrosion resistance, high strength and low critical transition temperature of cold embrittlement.

Strengthen system construction. The system itself has a certain binding force, which specifies the rights and obligations of employees. It is a passive management means for employees. Its purpose is to promote each employee to develop good professional habits, form good behavior norms, and promote the improvement of enterprise management level.
