Material selectionWhat Specialty Materials Work Best for Pressure Instrument Components?

  • Nickel and High Temperature Alloys
  • Stainless Steel and Specialty Steel
  • Aluminum Alloys
  • Copper Alloys

Nickel and High Temperature Alloys

Nickel steel alloys are extremely popular for Pressure Transducer housings and fittings. It is designed for critical applications where extreme conditions are required. This demand is due to its increased hardness, tensile strength, and elastic limit, all without reduced ductility. It also maintains strength at elevated temperatures as high as 1,050ËšC to 1,200ËšC. The nickel-based super alloys Inconel and Hastelloy are also used extensively.

Below are some of the grades in stock:
Nickel-Chromium Alloys – Inconel®
Inconel 600
Inconel 617
