Carbon Structural Angel Steel S420 S460 Equal Unequal Steel Angle Bar Iron Steel

Carbon Structural Angel Steel Equal Or Unequal Steel Angle Bar Iron Steel

The manufacturing process of angle is relatively simple, the production process can be divided into two kinds of hot rolling and cold bending, hot rolling is used for large size angle, cold bending is generally smaller. The standard process is to use billet (such as billet) through the special steel mill multiple repeated rolling gradually rolled into ∨ shape, the material has , in the corner of the inner side of the transition arc, mechanical properties are reliable; and small workshop production is directly rolled (bending) into the plate or strip, the corner of the inner side of the transition arc is not there, and because of the bending into the corner of the inner stress is greater, the mechanical properties of the poorer. The important point is that the material is not, and may even be "bar steel", so that the angle to buy back generally can not be bent, can not be welded, . More can take the long and short drill holes. Shandong and Yixin focus on steel structure for more than 20 years, all kinds of steel structure are involved, quality and experience can be reassuring.
