Frequently Asked Questions

What are the advantages of stainless steel 17-4?

17-4 AR is a high-quality stainless steel with good strength, hardness, durability, and ductility which makes it ideal for applications that require high mechanical properties. This steel can be used in abrasive environments because it has good wear resistance as well. Other properties include corrosion resistance, easy machinability, weldability, and heat treatability.

What is the UNS S17400 steel alloy made of?

17-4 AR contains 15-17% chromium, 3-5% nickel, 3-5% copper, and 3-5% manganese mixed with small amounts of other elements such as silicon, carbon, and phosphorus. It belongs to the ASTM A693/A564 standard for precipitation-hardening steels.

What is the hardness of steel 17-4 after heat treatment?

The level of hardness depends on the heat treatment being used which in turn depends on the specific application, so 17-4 AR can be treated for a range of H900 to H1150 hardness.

Is 17-4 AR stainless steel magnetic?

Yes, 17-4 AR stainless steel is ferritic and displays magnetic properties. But the magnetism varies by specific composition and microstructure and can be affected by heat treatment processes like annealing, which reduce its strength.
