AISI 904L – 1.4539
this material is a stainless steel belonging to the austenitic steel family. Its excellent performance makes it a super austenitic steel.
It appears to be the best solution among stainless steels before moving on to special steels such as nickel alloys.
Its very low carbon content, combined with high percentages of chromium and molybdenum guarantee great resistance to corrosion.
Nickel and copper, on the other hand, ensure good performance against breakages due to stress corrosion.
Its optimal operating range is up to 600°C, but for short periods it can withstand temperatures of up to 900°C.
It is used on reactors and in all those environments characterized by high corrosivity.
It is therefore superior to AISI 316 in terms of characteristics and performance.
The 904L undergoes water heat treatment through solubilization at 1100°C.
The most common format we supply is round bars, but it is also available in plates, bars and sheets.
Through steel mills and international producers, we also chance to supply all the pipelines parts, such as pipes and fittings, and not last flanges, for the most complete offer possible for this material.
