Product Details

17-4PH Studs
17-4PH Studs is a metal rod or bar with threads on both sides. It also known as double-headed screws or studs, used to connect two parts together. General for mining machinery, bridges, cars, motorcycles, boiler steel structure, hanging tower, large span steel structure and large buildings. 

We tend to use studs when the parts need to remove frequently, because the thread will be worn if install and remove often, then we need to change the studs.
Applications:
1.Offshore platform, helicopter deck, other platforms
2.food industry
3.Pulp and paper industry
4.Aerospace (turbine blades)
5.Mechanical components
6.Nuclear waste bucket
17-4PH 17-4PH alloy is precipitated, hardened, martensitic stainless steel.
17-4PH alloy is made of copper, niobium / columbium consisting of precipitation, hardening, martensitic stainless steel.
This grade has high strength, hardness (up to 300 ° C / 572 ° F) and corrosion resistance and other characteristics.
After heat treatment, the mechanical properties of the product more perfect, can reach up to 1100-1300 mpa (160-190 ksi) of the compressive strength.
This level can not be used at temperatures above 300 ° C (57 ° C) or very low temperatures, and it has good corrosion resistance to both atmospheric and dilute acids or salts, and its corrosion resistance is the same as that of 304 and 430.
