30CrMnSiA Alloy Structural Steel Introduction 
30CrMnSiA,30CrMnSiA Steel, Alloy Structural Steel
30CrMnSiA Alloy Structural Steel is a medium carbon,high strength steel of poor welding properties.
30CrMnSiA Alloy Structural Steel Delivery state
30CrMnSiA Alloy Structural Steel Material should be delivered at hot-rolled or hot wrought conditions. Once the demander requires(and stipulates in the contract),hot processing condition(annealing, normalizing or high-temperature backfire) can also be adopted.
30CrMnSiA Alloy Structural Steel Application
30CrMnSiA Alloy Structural Steel is used for manufacturing plate, intensity of general building and all kinds of engineering machinery, such as mining and all kinds of engineering construction, excavator, the rig with electric wheel, mine car, its excavator, loaders, bulldozer, all kinds of crane, coal hydraulic support and other machinery and other structures.
