Duplex stainless steel grades are high strength and extremely corrosion resistant materials. They are an ideal candidate for a wide range of applications. They are chemically balanced to offer a ferrite and austenite structure possessing 40 to 60% ferrite configuration subsequent to solution annealing. Popularly used duplex steel grades are 2205 and 2507. Stainless steel … Continue reading Duplex stainless steels-Complete Guide

Superalloys are heat resistant alloys containing Nickel, Nickel-Iron, Nickel-Cobalt or Nickel-Chromium-Molybdenum that offer a great combination of mechanical strength and corrosion resistance properties. These are commonly utilized in gas turbines, coal conversion units, chemical process industries and for various specialized operations that need high resistance to heat and corrosion. The significant attribute of nickel based … Continue reading Nickel Based Alloys-Phases and Corrosion Resistance

Nickel is obtained as sulfide, usually combined with arsenic, copper and cobalt. Meteorites found in space always consist of some magnitudes of nickel, iron and cobalt however it is not found as a native metal. Nickel in purity of 99.9% doesn’t include cobalt and sulfur, is received from Mond Process, and it is the material … Continue reading Nickel Commercial Metal-Industrial Specifications

The reason of development of Nickel based super-alloys is their need for use in applications that need excellent corrosion resistance at the temperatures varying from cryogenic to high limits. Chemical industry is also one of those sectors that widely use these alloys. corrosion resistant nickel alloys  

This post shows the complete insight of FeCrAl based resistance heating elements, their applications, benefits and technical data. FeCrAl or iron-chromium-aluminum alloy heating element grades are made by modifying the chromium and aluminum contents. They are excessively resistant to sulfiding, carburizing and oxidizing conditions at the very high temperatures. FeCrAl is an economical alternative to Nichrome … Continue reading Alchrome (Iron-Chromium-Aluminum) FeCrAl Electric Resistance Heating Elements
