Basisintroductie tot ferritisch roestvrij staal

Ferritic stainless steel (400 series) has a chromium content of 15%~30% and a body centered cubic crystal structure. This type of steel generally does not contain nickel, and sometimes also contains small amounts of elements such as Mo, Ti, Nb, etc. This type of steel has the characteristics of high thermal conductivity, low expansion coefficient, good oxidation resistance, and excellent stress corrosion resistance. It is mostly used to manufacture components that are resistant to atmospheric, steam, water, and oxidative acid corrosion. The price of ferritic stainless steel is not only relatively low and stable, but also has many unique characteristics and advantages. It has been proven that in many application areas where austenitic stainless steel (300 series) was originally considered the only option, ferritic stainless steel is an extremely excellent substitute material. Ferritic stainless steel does not contain nickel, and the main elements are chromium (>10%) en ijzer. Chroom is een bijzonder corrosiebestendig element in roestvrij staal en de prijs ervan is relatief stabiel.
