17-4 PH (H900) Stainless Steel

Material Specifications:

These custom head studs are manufactured from 17-4 PH H900 which is a version of 17-4 PH stainless steel that's been specially heat-treated. The "H900" refers to the fact that the material has been aged at around 900°F (482°C). This treatment boosts its strength and hardness compared to the standard, annealed form.

The H900 process gives the steel much higher tensile and yield strength, making it ideal for demanding applications.

Thanks to the heat treatment, 17-4 PH H900 is very hard, which helps it resist wear and abrasion.

These studs also still offer solid corrosion resistance.

Ultimate Tensile Strength (UTS): Minimum of 190,000 PSI

Yield Strength (YS): Minimum of 1172 MPa / 170,000 PSI

Hardness: 40 HRC
