 PRODUCT DESCRIPTION

1.4509 (441) Sheet and Plate

Stainless steel producers have an ongoing programme of development designed to produce new grades. These new grades are sometimes developed for specific end uses and sometimes to improve upon an existing grade. 


Type 1.4509 spans both of these two areas since it was developed for a particular range of applications in certain industries where it can be used in place of type 1.4301 (304). On some aspects, its properties and performance in service are actually superior to 304 whilst on others it falls between 430 and 304. Notably however, it is also lower cost than 304. 


Type 1.4509 can be referred to as a 'Super-Ferritic' 


Features:

~ Good for Deep Drawing

~ Good Weldability 

~ Good pitting corrosion resistance

~ Good brightness

~ Polishes well


Applications/Industries:

The main target sector is catering equipment to replace grade 304
