Steel. Some Surface Treatments – PART 2
In the previous article, we discussed some of the most common surface cleaning methods, including degreasing and sandblasting. Today, we will focus on additional treatments used for stainless steel and alloy steels. Acid Pickling Before pickling, the material must be thoroughly cleaned in order to remove any grease, oil, or insoluble residues from the surface. […]
Steel. Some Surface Treatments – PART 1
Hot-processing operations such as forging, rolling, welding, and heat treatment generate surface oxidation on carbon steels, alloy steels, and stainless steels. This oxidation layer, commonly known as āscaleā or āmill scaleā, must be removed because it can create problems during stamping and drawing operations. The presence of scale may compromise the corrosion resistance of the […]
