The chemical differences between the Monel, Inconel, Incoloy and Hastelloy grades


The role of different elements in nickel alloys Nickel alloys are the most widely used and strongest superalloys. Nickel in nickel alloys is an austenite stabilizing element that enables nickel alloys to maintain the FCC structure, so that more other alloying elements can be dissolved, while maintaining good structural stability and material plasticity.


Introduction of pure nickel wire and nickel mesh


Pure nickel wire is mainly used to manufacture electron tube cathode, anode grid side rod, tube needle, etc. It has good mechanical properties and corrosion resistance to alkalis, such as sodium hydroxide. It also has better electrical, thermal and magnetic controllability characteristics. Applications include food and synthetic fibre processing, heat exchangers and the chemical and power industries. Typical manufacturing r


Features and Principles of Vacuum Induction Furnace


With the rapid development of my country in the fields of high-speed rail, nuclear power, petroleum and petrochemical, aerospace and other fields, higher and higher requirements are put forward for steel materials: higher strength, harsher corrosion resistance, high temperature resistance, and stronger fatigue resistance etc., and vacuum induction melting technology is an important guarantee for the production of high-end special steel. Among many special heating or melting methods, induction heating technology is used to smelt and prepare metal materials, and it can accurately control gases, non-metallic in


Knowledge of Nickel Alloys


Nickel alloys are alloys composed of nickel-based additions of other elements. Nickel has good mechanical, physical and chemical properties. Adding appropriate elements can improve its oxidation resistance, corrosion resistance, high temperature strength and improve some physical properties.


Application and Development of Nickel Alloy in Aviation Field


R.F.Smith of the United Kingdom discussed the development of four aspects of nickel alloys recently used in aviation, the first is the disk alloy; the second is the low expansion superalloy; the third is the superplastically formable nickel-based superalloy (Inconel718 alloy); the fourth It is a low expansion alloy (Nilo) for composite preparation tools.
