14HGS General Purpose Thick Plate and Wide Width Steel Surface Quality

14HGS edge (except for the surface of the rolled edge) should not be cracked, transparent fracture, coarse sand and slag shell, raised bubbles, ripples, cracks, casting scars, milled impurities and iron oxide scale.

Eliminate surface defects by sanding method. The depression created by sanding should have a gentle transition, and its depth-to-width ratio should not be less than 5:1. Grind with an angle grinder or other tool that cannot change the characteristics of the rolled product.

The grinding depth of the defect should not exceed the limit negative difference of the rolled steel specification.

14HGS individual area of the grinding area is not more than 100 cm*, the grinding depth can exceed the thickness error limit of 5%, but not more than 3mm, and the sum of the area of the depth should not exceed 2% of the area of the whole rolling plate.

If the grinding position on both sides of the rolled plate happens to be in the same position, the cumulative grinding depth should not exceed the negative value of the steel plate thickness limit. The total area of the grinding surface should not exceed 20% of the area of the steel plate.

There should be no scratches visible on the sanded surface and no convex shoulders in the sanded edge area.
