AISI 314 (EN 1.4841)
Due to its high nickel content, it is austenitic even at room temperature and therefore does not get hardness. It is also a non-magnetizing steel.
It is in the class of austenitic stainless steels due to its high nickel content in the stainless steel class. It is referred to as a material with high temperature resistance since the phase structure does not change at high usage temperatures and room temperature and is suitable for such applications. High nickel and chromium content also provides high corrosion resistance.
