Stainless Steel Flat Metal Bar Uses
Different grades of stainless steel flat bar have different applications due to their respective properties.
For instance, 303 ss flat bar are often used in nuts and bolts, aircraft fittings, gears, screws, shafts, electrical switchgear components, bushings.
Meanwhile, 304 SS flat bars can be used in food processing equipment, beer brewing, milk processing, wine making, kitchen benches, sinks troughs, architectural paneling, and heat exchangers.
However, due to its high level of security, 316 SS flat bars are more expensive than 304. Therefore, it is commonly used in food preparation equipment, chemical containers, coastal architectural paneling, laboratory benches and equipment, railings and trim, boat fittings, woven or welded screens for mining, threaded fasteners, and springs.

Bending a stainless steel flat bar requires a few simple steps. Firstly, gather a hammer and an anvil. Next, strike the stainless steel flat bar lightly and gradually increase the pressure until you achieve the desired bending angle. However, it is important to be careful not to over-tap, as it may cause permanent damage or fracture to your stainless steel flat bar. By following these guidelines, you can effectively bend the stainless steel flat bar without compromising its integrity.
