A709 Gr 50 low alloy steel,, Manganese steel plate is a low alloy high strength steel plate with good weldability. Manganese steel plate is the main material of general pressure vessel. Manganese steel plate is mainly used to make engineering structural parts, roof beam of workshop and tower crane tower body. Manganese steel plate has high rupture strength and creep strength at high temperature and good impact toughness at low temperature. High strength steel is a kind of wear-resistant steel for heavy industry. Its application fields include quarrying, mining, mining, coal industry, casting and steel industry, etc.
Good weldabilityBecause of its low carbon content, low alloy element content, good plasticity and low hardenability, this material A709 Gr 50 low alloy steel is not suitable to have quenching structure or crack at the weld. The cold and hot pressure processing performance is good. Because of its good plasticity and small deformation resistance, it is not easy to produce cracks after pressure processing. Good corrosion resistanceUnder various atmospheric conditions, it has higher corrosion resistance than carbon steel.
A709 Gr 50 low alloy steel,Flame cutting is a common hot cutting method in modern iron and steel industry. It is also a very important part in the process of iron and steel processing. Flame cutting can cut very thick carbon steel, its cutting range is very wide, can cut 6mm-200mm thick steel plate. In cutting thick and medium plates, flame cutting plays an important role. And with its price advantage, flame cutting has always occupied a certain market share in thin plate cutting also.
A709 Gr 50 low alloy steel,The consistent tenet of honest management! Know the needs of customers, for the needs of customers, urgent customers think!
