Alloy 330 resists oxidation up to 2100º F (1150º C). The high silicon content promotes resistance to carburization. Alloy 330 Stainless fasteners are used in environments where thermal cycling is frequent. Typical applications would be heat exchangers, gas turbines, radiant tubes, salt pots and perlite processing. Navaratna stocks hex bolts, hex nuts and flat washers in Alloy 330. The primary diameters in stock are 1/2-13, 5/8-11 and 3/4-10. Other diameters and other configurations (socket cap screws, square head set screws) will be manufactured to order.
