Product details

17-4 is a chromium-nickel-copper precipitation hardening stainless steel used for applications requiring high strength and moderate level of corrosion resistance

The most well known precipitation hardening steel is 17-4 PH. The name comes from the additions 17% Chromium and 4% Nickel. It also contains 4% Copper and 0.3% Niobium. 17-4 PH is also known as stainless steel grade 630

17-4 pH stainless steel has a mean coefficient of thermal expansion of 6.0 x 10-6 in/in/°F with H900 heat treatment, whereas 316L ranges from approximately 9 to 11 x 10-6 in/in/°F. Technology such as thin film is limited to 17-4 PH because the temperature of the sputtering process is too high at the diaphragm

Frequently asked by buyers
What heat treatment is applied to 17-4 PH round bars to achieve high strength?

The 17-4 PH round bars undergo an H900 precipitation hardening heat treatment to significantly increase their strength and durability.

How does the thermal expansion coefficient of 17-4 PH compare to 316L stainless steel?

17-4 PH stainless steel has a lower coefficient of thermal expansion (6.0 x 10^-6 in/in/°F) than 316L stainless steel (approximately 9 to 11 x 10^-6 in/in/°F), which makes it more stable under thermal cycling.

Is 17-4 PH round bar suitable for thin film technology applications?

Yes, due to its lower thermal expansion and heat resistance, 17-4 PH is used in thin film technology where high sputtering temperatures would normally degrade other materials.

Can 17-4 PH round bars be used in corrosive environments?

Yes, the 17-4 PH round bar provides moderate corrosion resistance making it suitable for chemical processing and petrochemical applications.

What industries commonly use 17-4 PH round bars?

Industries such as aerospace, chemical processing, petrochemical, nuclear energy, and electronics manufacturing often use 17-4 PH round bars for their mechanical strength and corrosion resistance.
