Sachiya Steel International is One Of The Leading Manufacturer And Exporter Stainless Steel 17-4PH Bolts And 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.
The valuable combination of high strength, good corrosion resistance and toughness in Alloy 17-4 PH Hex Head Nuts over both base metals and welds gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs. To increase their yield strength, these Alloy 17-4 PH Square Bolts are subjected to heat treatment during precipitation hardening (PH) or age hardening. High strength of Alloy 17-4 PH Square Nuts is maintained to approximately 600 degrees Fahrenheit (316 degrees Celsius).
These Alloy 17-4 PH Eye Bolts has adequate resistance to atmospheric corrosion or in diluted acid salts where its corrosion resistance is equivalent to Alloy 304 or Alloy 430. Alloy 17-4 PH Eye Nuts combines high strength, hardness (up to 572 Degree F / 300 Degree C), and corrosion resistance. Known for its’ corrosion resistance characteristics, the different shapes and finishes of these Alloy 17-4 PH T-Bolts make the composition suitable for a wide variety of environments.
