As the name suggests, have austenitic configuration metallographic. Esta familia de aceros se obtiene adicionando elementos formadores de Austen, such as nickel, manganese and nitrogen. The chromium content usually ranges from 16 to the 26% and its carbon content is always kept very low, en el Rank de 0,03 at 0,08%. Chromium provides oxidation resistance and corrosion resistance to approximate temperatures of 650 ° C in a variety of environments. Nickel, and to a lesser extent manganese, se adiciona a estos aceros para estabilizar la fase austenítica en un amplio Rank de temperaturas y evitar así su transformación en martensita cuando son enfriados rápidamente a Ambient temperature.
Austenitic stainless steels are the family with the largest number of alloys available, series integrates 200 and 300 AISI. Popularity to its excellent formability and superior resistance to corrosion should. Its features are as follows:
• Excellent resistance to corrosion.
• Hardened by cold working and heat treatment not.
• Excellent soldabilidad.
• Excellent hygiene and cleanliness factor.
• Formed simple and easy transformation.
• Have the ability to be functional in extreme temperatures, low temperature (Cryogenic) preventing embrittlement, and high temperature (hasta 925°C).
• They are essentially the magnetic. They can be magnetic after cold be treated. The Degree de magnetismo que desarrollan después del trabajo en frío depende del tipo de Alloy de que se trate.
