Is hastelloy more expensive than stainless steel?
Hastelloy and stainless steel are two commonly used metal materials that are widely used in various fields. Although their names sound similar, they are quite different in terms of ingredients, properties, and applications. This article will introduce the differences between Hastelloy metal and stainless steel to help readers better understand these two materials.
First of all, Hastelloy is a high-temperature, corrosion-resistant alloy, usually composed of nickel, chromium, molybdenum, cobalt and other elements. The nickel content is usually between 40% and 70%. The main characteristics of Hastelloy are excellent corrosion resistance, high temperature strength and wear resistance. It can resist extreme environments such as acid, salt, and chemical corrosion, and can still maintain a certain strength and stability under high temperatures. Therefore, Hastelloy is often used in chemical, petroleum, aerospace and other fields.
In comparison, stainless steel is a regular steel with added elements such as chromium and nickel to improve its corrosion resistance. The main components of stainless steel are iron, chromium, nickel, etc., of which the chromium content is usually between 12% and 30%, and the nickel content is usually between 8% and 12%. The main characteristics of stainless steel are poor corrosion resistance, wear resistance and high temperature resistance. Stainless steel is widely used in general environments, such as food, construction, medical equipment and other fields.
