E320LR-16

< CLICK HERE for additional information on this alloy >

 

E320LR-16 is similar in composition to 320 stainless steel but with carbon, silicon, phosphorus, and sulfur controlled to lower limits and columbium and manganese kept to a narrower range.  The resulting composition is designed to reduce the possibility of microfissuring.  Low heat input is advised when welding with E320LR-16 electrodes.

 

Typical Applications:  tanks, process piping, heat exchangers for the chemical processing industry
