Frohn manufactures blasting media as well as accessories needed to test the blasting process, including almen strips. Its cut-wire media is available as cut or conditioned for reproducible shot peening automotive and aircraft transmission parts. According to the company, its structural purity and grain shape facilitate precisely configured blasting for maximized service life and efficiency. The company also offers specialty shot blast media, stainless steel cut wire (SAE 302/304/430 grades); Zinc-Al-Alloy and Al-Alloy cut wire. Spherinox CR is an effective substitute for conventional CrNi blasting media. It presents the optimal price-performance ratio and is used specifically in the various stages of aluminium processing. This media is available in multiple sizes for use in diverse applications.
Surface finish types for commercially supplied stainless steel sheet are detailed in various standards. ASTM A480-12 and EN10088-2 are two; BS 1449-2 (1983) is still available, although no longer active. These standards are very similar in that they define eight grades of surface finish for stainless steel. Grade 7 is “buff polished,” while the highest polish—the so-called mirror polish—is designated Grade 8
Metal fabricators that laser-cut with oxygen take steps to prepare parts better for powder coating.
Choice of equipment, media and compounds has a major impact on your finishing applications.
