In STAINLESS STEEL 17 4 PH BOLTS, the PH denotes that the fasteners have been precipitation hardened, and therefore these are some of the most robust stainless steel BOLTS. Therefore these possess the property of high strength because of the PH present and can be used at high-temperature levels. These are precipitation hardened stainless steel BOLTS. They are widely known for their tensile strength and their property concerning their mechanism, which can help them stand even at 600 degrees Fahrenheit. 17-4 Ph Set BOLTS are an alloy made up of chromium and nickel where the content of chromium is considerably high. These are four times greater strength than the 316 stainless steel fasteners. These fasteners are primarily used in applications where great strength is required. Therefore they are also highly resistant to corrosion. Another advantage here is that they also have niobium in specific amounts. Therefore, these can be easily fabricated, and the fabrication cost of these fasteners is also very low. This is one of the reasons why it is preferred. As the tensile strength is high, there is an option for the users to reduce the cross-sectioning of the structure, which eventually leads to a structure with low weight and eventually reduces the price of the product.

Even though 17-4 Ph SS Nuts are used for corrosion resistance purposes, they are preferred for their tensile strength even if they are moderately corrosion resistant. This in itself proves how strong these stainless steel fasteners are compared to the others available.
