304 Stainless Steel

304 stainless steel is one of the most common grades of stainless steel. This steel has a #2B finish. It is an excellent choice for functional and decorative parts. Laser-cut stainless steel may have a small amount of dross (burr) on the underside. Parts may also have cosmetic imperfections/scratches as a result of the manufacturing process. Parts over 75mm/3 inches and greater than 1.5mm/0.060" thickness can be deburred for a grained finish. For parts under this size, contact us for finishing options.
