Material of construction for Hydrogen Peroxide Equipment

What metals and materials are best for containers and plumbing for very high test (80+ percent) H2O2?

temperatures: -10 and 100 degrees Celsius

pressure: up to 100 psi

Specifically, are there any issues with stainless steel and Teflon?

Any other suggestions?

I only used to work with room temp peroxide at 25% and low if any pressure but the tanks we used were 316 Stainless. Lower grades of steel caused problems with stability on the peroxide. The tanks were also regularly passivated with 10 to 30% nitric acid.
