Nascent Pipe & Tubes offers an extensive collection of Alloy 17-4 PH Bolts / Nuts, where short - time and low - temperature heat treatments minimize distortion and scaling. Typical usage of Alloy 17-4 PH Hex Head Bolts is seen in applications requiring high strength and a modest level of corrosion resistance. These Alloy 17-4 PH Hex Head Nuts can be heat treated to high levels of strength and hardness, and features corrosion resistance and machinability comparable to austenitic 304 stainless.
