Applications

FeCrAl alloy is used as catalytic substrate that is a metallic substrate offering various benefits as compare to ceramic substrates. A metallic substrate offers more resistance to shock and vibration, it offers higher conductance to heat rather than ceramic. Moreover,it can be manufactured easily in thin foil and offers honeycomb structure to render broad surface area … Continue reading FeCrAl Resistance Heating Alloy-Scaling Resistance

A fixed position electric heater produces heat through the passage of current to the heating element that is made of a Nichrome resistance heating wire Ni80Cr20. The Nichrome heating element can be covered in a metal sheath shielded with a magnesium oxide powder or can be kept in open coil geometry.Generally, the heating element is … Continue reading Nichrome in Fixed position electric heaters

A study was conducted to determine if nichrome resistance heating wire or stainless steel immersion heater is better for use to heat water in a boiler container. These two heaters were designed to provide power about 150W.  Introduction The aim of this analysis is to find which of the two conducting elements-Nichrome electric resistance heating … Continue reading Nichrome Wire or Stainless steel immersion heater! Which to choose?

Outstanding weldability was one of the basic goals in the alloy development programs. While the composition developed a matrix that was necessarily a solid-solution kind, the presence  of a relatively high content of niobium and its participation in a prolonged aging reaction caused concern for resistance to strain induced cracking while post-weld exposure to moderate … Continue reading Weldability features of Inconel alloy 625

The solutions of sulfurous acid and calcium bisulfate utilized to prepare sulfite paper pulp are also of extremely attacking nature in the dilute solutions like exist in spent cooking liquor or in the paper itself. The corrosion resistance is superior and significant magnitude of Monel … Continue reading Corrosion resistance properties of Monel alloy 400

With nominal exceptions, organic acids are weak and non-oxidizing in nature. The usually encountered acids are monocarboxylic acids such as formic acid, acetic acid, propionic acid and butyric acids. Commonly the corrosivity of these acids becomes weaker with increasing the length of carbon chain. Therefore, formic acid is the most powerful corrosive acid; aeration and … Continue reading High Nickel alloy’s corrosion behavior in Organic acid

Nickel alloy 200 The excellent property of Nickel alloy 200 is its resistance capability against caustic soda and other alkalies (excluding ammonium hydroxide). The alloy is not corroded by anhydrous ammonia or ammonium hydroxide in concentrations about 1%. Higher concentrations can result in quick corrosion in the availability of dissolved oxygen. Nickel alloy 200 provides outstanding … Continue reading Nickel alloy’s resistance performance in Alkali media
