Super-Austenitic Stainless Steel Alloys: A Comparison

Super-Austenitic Stainless Steel Alloys: A Comparison

Oct 7, 2015

In the high-purity and sanitary industries, products such as shampoos, conditioners, deodorants, sports drinks, ketchup, salsa, active pharmaceutical ingredients, etc. require extremely corrosion-resistant material to withstand the high concentration of chemicals (chlorides), high temperatures, and low pH. When faced with similar corrosion-resistant alloys, your purchasing decision should be influenced by which material is readily available.

Have you ever wondered why welds fail? When welding in a high purity environment, several factors can render a weld unacceptable: heat tint, a lack of...

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

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...

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:
