What’s the Difference? AL-6XN™ vs C-22

Nov 30, 2011

High temperatures, low pH, and aggressive chemicals call for a material that exhibits the high corrosion resistance that traditional stainless steel alloys fail to attain. There are many alloys available to address the corrosion issues; but what makes super-austenitic stainless steel alloy AL-6XN® and nickel alloy C-22 the favorite materials for highly corrosive environments? Are the properties more attractive, or is the availability of the material in the required forms more desirable? Is one better than the other? Both AL-6XN and C-22 have a face-centered cubic lattice structure and contain...

This brief article will deal with a small part of a much bigger topic: surface finish. We will be looking at commercially available finish options and how they are measured. The surface finish of process systems components plays a very integral role in the cleanability and sterility of the system. The most commonly used unit for surface finish is...

Cut the Hassle: Hastelloy C-22 vs. C-276

Jun 21, 2011

Material selection can be a difficult decision when you don’t understand the differences between two materials with almost the same cost. Have you ever asked for Hastelloy C-276 material and been recommended Hastelloy C-22 instead? Have you wondered what the difference is between them, and why one should be preferred over the other? Here are few reasons why C-22 is a better choice than C-276:

For any project requiring alloy equipment, the best thing to do is look at the experience and expertise with the alloy. The first requirement for a fabricator should at a minimum be ASME Section VIII Div 1 certified for the manufacture of pressure vessels, even for equipment not requiring pressure service.

Alloy Equipment – Realizing the Benefit of Proper Selection

Jan 20, 2011

Many of our customers whose processes utilize high chloride materials or are subject to extremely corrosive applications know that the life span of a vessel which uses a properly specified nickel alloy or reactive (commercially pure) metal can justify the additional expense. While the cost of an alloy tank itself can be higher, remember to factor the additional costs incurred from downtime, maintenance, or replacement, including removal and installation.
