Hastelloy is a nickel-based alloy, which is a difficult material to machine. The lkalloy company suggests the use of integral tools to enhance the rigidity of the tools. If the tool is made of carbide, it is inefficient. Efficiency can be improved if tempered tools with better toughness are used. For finishing, nickel or cobalt-based high-temperature alloys can be used with CBN tools. The alloys are widely used in the chemical and petrochemical industries, e.g. for chlorine-containing organic components and catalytic systems. The material is particularly suitable for high-temperature inert inorganic and organic acids (e.g. formic and acetic acid) mixed with impurities in seawater corrosive environments.
What is the difference between Hastelloy and stainless steel?
In fact, there is a clear difference between the two, Hastelloy, nickel-based alloys are usually understood as nickel-based alloys, that is, nickel has a high percentage, usually greater than 50.%, such as Monel, Hastelloy B, C series, etc., and the stainless steel is basically “steel”, so the proportion of iron is higher. For example, 304L is a stainless steel that contains more than 70% iron, although 9% nickel.
Nickel-based alloys are alloys that have high strength and a certain degree of oxidation and corrosion resistance at 650-1000°C. They are categorized into nickel-based alloys according to their main properties. According to the main properties, it is divided into nickel-based heat-resistant alloys, nickel-based corrosion-resistant alloys, nickel-based wear-resistant alloys, nickel-based precision alloys, and nickel-based shape memory alloys. Based on the matrix, superalloys are categorized into iron-based superalloys, nickel-based superalloys, and cobalt-based superalloys. Among them, nickel-based superalloys are called nickel-based alloys.
The above is the introduction of the difference between hastelloy and stainless steel, I hope it will help you. If you want to know more about Hastelloy, high-temperature alloys, stainless steel, and other materials information, welcome to continue to close lkalloy website.
