17-4 PH Stainless Steel Fasteners

What are 17-4 PH stainless steel fasteners?

Fasteners whose chemistry consists of 17% chromium and 4% nickel, and 3–5% copper are a grade of Martensitic stainless steel. The name of these martensitic precipitation-hardened stainless steel fasteners is the amalgamation of their chemical composition.

17-4 ph bolt vs 17-4 ph carriage bolt

While both a carriage bolt and bolt are threaded fasteners, the former has a tapered construction which will aid in mating an existing thread or the creation of its own thread on the material. A 17-4 ph bolt holds objects together with a nut and washer.

Benefits of 17-4 stainless steel bolts

The alloy can exhibit corrosion resistance properties up to 316 °C without compromising its high hardness. If the bolts have undergone averaging, they tend to have improved resistance to stress-related cracking. Lastly, because it is a martensitic grade, these 17-4 PH Stainless Steel Fasteners are magnetic.

How to calculate 17-4 ph shoulder bolts sizes?

To calculate the size of a shoulder bolt, they need to be specified by diameter and length. For e.g. – for a shoulder bolt measuring ¼ × 1 inch, the fastener will have a shoulder diameter of ¼ inch. and a shoulder length of 1 inch.

How to prevent corrosion on 17-4 PH Hex Head Bolts?

The highly alloyed nature of this material gives it superior resistance to corrosion along with higher mechanical strength, even in high temperatures. The use of heat treatment makes these fasteners stronger. Hence, they are resilient to corrosion in such conditions. One can still improve the corrosion resistance of this material by applying coatings on its surface. Using zinc coating, or galvanization to coat the outer layer of the alloy improves its corrosion resistance properties.

What is the yield strength of 17-4 stainless steel nuts?

The yield strength of 17-4 stainless steel nuts varies in different conditions. If the alloy was exposed to heat treatment in conditions H1150-D and H1150, its yield strength would be 105,000 psi. The highest yield strength (170,000) can be obtained under condition H900. In conditions like H1075 and H1025, the fasteners exhibit a yield strength of 125,000 & 145,000 respectively.
