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

Types of Silver Demand The demand for silver metal can be categorized into: Production and Investment. The production demand describes cultivating silver into a specific product form like jewelry, silver strip, silver mesh and silver foil that are used as a component in semiconductors, chemical compounds and soldering. Investment demand arises when silver is used … Continue reading Silver’s Demand Prediction in 2015 by Heanjia Super-Metals

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

Inconel alloy 718 was discovered in 1980s for downhole apparatus.  The need for meeting high pressure gas wells demands a high strength alloy with excellent corrosion resistance to gas containing high carbon dioxide and hydrogen sulphide for completion apparatus. The superalloys like Hastelloy C-276 were available and provided outstanding corrosion resistance to the anticipated fluids. … Continue reading Inconel Alloy 718 for oil and gas industry

Nichrome heater wire is of two types Nichrome A and Nichrome C. Nichrome A is made of NiCr alloy containing 80% nickel and 20% chromium. It has lower temperature coefficient of resistance as compare to Nichrome C. Nichrome A has service temperature up to 1150oC or 2100oF. Nichrome C heater wire is made of NiCr … Continue reading Nichrome A and Nichrome C Industrial heating wires

Earlier it was assumed that copper-nickel alloys provided sufficient corrosion resistance in the fresh waters while use in the heat exchanger services. The materials like austenitic stainless steels and nickel-chromium-iron alloys were mentioned essential only while operation in the brackish water or sulfide polluted water, because these were very costly for use in ordinary fresh … Continue reading Performance of heat exchanger materials
