Stainless steel 1.4509

Grade 1.4509 was mainly developed for a particular range of applications in certain industries where it can be used in place of type 1.4307 stainless steel. On some aspects, its properties and performance in service are superior to 1.4307, whilst on others it falls between 1.4307 and 1.4016. Main advantage of Ti/Nb alloying is its enhanced deep drawability feature.
