Unisteel & engineering are one of the leading manufacturer, supplier and exporter of best quality Stainless Steel 17 4H Fasteners, which has a number of outstanding attributes to provide like ruggedly constructed, lightweight, highly durable and more.
Our Stainless Steel 17 4H Socket Head Cap Screws is also used in Laboratory benches and machinery, Food preparation machinery mainly in chloride atmospheres, Coastal architectural lining, railings and trim, Chemical containers etc. The high chromium and nickel content of SS 904L Threaded Screws make it erosion resilient in both rusting and plummeting atmospheres.
We provide SSl 17 4H Socket Set Screws which is a reasonable solution for a lot of functions where the 300 series of alloys are inclined to chloride SCC. Wrought forms of Stainless Steel 17 4H Hex Head Screws (UNS N08904) are furnished in the solution heat-treated condition unless otherwise specified.
Type 17-4 PH Stainless steel is the most widely used of all of the precipitation- hardening stainless steels. Its
valuable combination of properties gives designers opportunities to add reliability to their products while
simplifying fabrication and offen reducing costs. Type 17-4 PH is a martensitic precipitation-hardening stainless
steel that provides an outstanding combination of high strength, good corrosion resistance, and good mechanical
properties at temperatures up to 600o F (316oC). Its unique combination of properties make this alloy an effective
solution to many design and production problems.

Resistance to Corrosion :
Type 17-4 PH stainless steel has excellent resistance. It withstand corrosive attack better than any of the
standard hardenable stainless steels and is comparable to type 304 in most media. this has been tested in a
wide variety of corrosive conditions in the petrochemical, petroleum, paper, dairy and food processing
industries, and in applications such as boat shafting.
