Super austenitic stainless steel 904L (00Cr20Ni25Mo4.5Cu; UNS: N08904; EN: 1.4539) is a high-alloy austenitic stainless steel with low carbon content. It has good corrosion resistance in dilute sulfuric acid and is designed for environments with harsh corrosive conditions.

EN 1.4845 is a European standard stainless steel, corresponding to the American standard 310S (UNS S31008). It is an austenitic stainless steel and is mainly used in high temperature environments.

1.4122 stainless steel is a martensitic stainless steel. Due to its martensitic structure, it has strong magnetic properties.

1.4404 stainless steel, commonly referred to as AISI 316L, is a low carbon version of 316 stainless steel and is an austenitic type of stainless steel.

1.4306, also known as X2CrNi19-11 or AISI 304L, is a low carbon austenitic stainless steel.

316L stainless steel is an austenitic stainless steel and is usually non-magnetic. This is because the austenite structure itself is not magnetic.
