A299 advantages and disadvantages of hot-rolled plates

Bebon International can offer A299 hot-rolled plates and Cold-rolled plates,here analysis A299 advantages and disadvantages of hot-rolled plates.

A299 hot-rolled plates advantages:

A299 hot can significantly reduce energy consumption and reduce costs. A299 hot-rolled metals and alloys can improve processing performance, the state of coarse grains will cast broken crack healing significantly reduce or eliminate casting defects, the cast structure into deformation organization, improve the alloy processing performance. Hot usually large ingot, a large rolling reduction not only improves the production efficiency, but also increase the rolling speed, to achieve continuous rolling process and automation to create the conditions.

A299 hot-rolled plates disadvantages:

A299 after hot rolling, the non-metallic inclusions inside the steel (mainly sulfides and oxides, and silicates) is pressed into the sheet, delamination (interlayer) phenomenon. Residual stresses caused by uneven cooling. Residual stresses in the absence of external force equilibrium of internal stress from a variety of hot-rolled steel has a cross-section of such residual stress, generally the larger beam cross-sectional size, the greater the residual stresses. Rolled products can be controlled very precisely the required mechanical properties, microstructure and properties of hot-rolled products not uniform. Difficult to control the thickness of hot-rolled products, control accuracy is relatively poor; rolled products, cold rolled products than the surface roughness Ra value is generally 0.5 ~ 1.5μm. Therefore, more generally as cold rolled products processed billets.

There are A299 advantages and disadvantages of hot-rolled plates,More information about the A299 steel we will always add.
