What is Hastelloy? What is the difference between Hastelloy and stainless steel?
I believe there are still many people who don't know what material Hastelloy is. In fact, we have come into contact with Hastelloy in many daily necessities. For example, the cutting tools we use are all made of Hastelloy, so today Shanghai Shanghu Alloy will learn about the relevant knowledge of Hastelloy and see what the difference is between Hastelloy and stainless steel.
What is Hastelloy
Hastelloy is a nickel-based alloy; it is a relatively difficult material to machine; it is recommended to use integral tools to enhance the rigidity of the tool. If the tool is made of carbide, the efficiency will be low. If you choose a cermet tool with better toughness, the efficiency can be improved. For finishing, CBN tools can be used for nickel-based or cobalt-based high-temperature alloys.
Alloys are widely used in the chemical and petrochemical industries, such as components and catalytic systems containing chloride organic compounds. This material is especially suitable for use in high temperature, inorganic and organic acids mixed with impurities (such as formic acid and acetic acid), and seawater corrosion environments.
The difference between Hastelloy and stainless steel
In fact, the difference is easy to understand. There are still differences between the two. First of all, let's look at Hastelloy. Nickel-based alloys are generally understood to be nickel-based alloys, that is, nickel accounts for the highest percentage, usually more than 50 %, such as Monel, Hastelloy B, C series, etc. Stainless steel is essentially a kind of "steel", so iron accounts for the highest percentage. For example, 304L, although it contains 9% nickel, the iron content reaches more than 70%, so it is a kind of stainless steel.
Nickel-based alloy refers to a type of alloy that has comprehensive properties such as high strength and certain resistance to oxidation and corrosion at high temperatures of 650 to 1000°C. According to the main properties, they are further 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. High-temperature alloys are divided into iron-based high-temperature alloys, nickel-based high-temperature alloys and cobalt-based high-temperature alloys according to different substrates. Among them, nickel-based high-temperature alloys are referred to as nickel-based alloys.
The above is what is Hastelloy and its related introduction. Although this term is very unfamiliar, it is encountered in our lives, so we can understand it so that we can know what we use. What materials are included? I hope you are interested in the above introduction. If you want to know other related information, please continue to pay attention to this website.
