Second, the ball flat bulb steel angles are mainly used in shipbuilding and bridge-building in the field of profiles, which is a marine ball flat steel for shipbuilding aid in the profiles. The main product features are: 1, good light circle, no pattern without rib edge angle, the other has a sculptured appearance of the steel surface or ribs would have resulted in a small flat steel and concrete bond strength, while other steel and concrete. adhesion force. 2, with the converter refining flat, mainly iron as raw material, the molten iron is less harmful elements, to produce flat steel quality is guaranteed. 3, continuous casting billet length high angle, flat cut-rate guarantees to meet the needs of users. Angle 345 Material: Q345 is a steel material. It is a low-alloy steel, widely used in bridges, vehicles, ships, buildings, pressure vessels. Q represents the yield of this material, unequal angle behind 345, refers to the yield value of this material at about 345. And the thickness of the material will increase its yield value decreases. Note: Q345 latest standards GB / T1591-2008 angle relative to the price of the old standard, the most obvious change is the Mn contents change from the original 1.0-1.60 corrected to ≤1.70, canceled the minimum limit.
