Stainless steel alloys make excellent additions in any field that they are used in. The grade used to produce them by Stainless Steel Fasteners Manufacturers In India would indicate the properties of the fastener. For instance, the economical grade 304 is an alloy that offers good strength at moderately high temperatures, with superior corrosion resistance properties. Therefore, this grade is recommended by every SS Nut Bolt Manufacturer In Mumbai, especially if the cost of the application is to be brought down.
On the other hand, grades like 316 or 321, or even 347 may be suited to manufacture Heavy Duty Stainless Steel Snap Fasteners, as they offer properties that are at a significantly higher level in comparison to grade 304. Some applications call for specialized components. For example, grade 316 is used in the manufacture of Stainless Steel Marine Fasteners because they have superior resistance to marine water, and they are also resilient to salt sprays and caustic solutions. While the corrosion resistance properties of Stainless Steel Fasteners range from good to excellent, it is possible to increase them by processing them further.
One such processed type of component are Coated Stainless Steel Fasteners, which offer excellent resistance to oxidation corrosion. Since a thick layer of zinc coats the surface of these fasteners, they remain protected from oxidation. Another chemical processing that delivers better corrosion resistance is by the manufacture of Coloured Stainless Steel Fasteners, some of which may contain a percentage of zinc. In addition to chemical processing, mechanical processing fasteners also yields a good result. The processing of Polished Stainless Steel Fasteners removes any excess metal that sticks out, thus smoothening the surface of the fastener.
