Cr-Ni-Mo austenitic steel 
 
   TYPICAL APPLICATIONS  
Chemical equipment
Mechanical parts used in the condition of corrosion resistance 
Bolt and nut
 
   PRODUCT DESCRIPTION  
The alloy is usually produced by AOD followed by electroslag refining (ESR).
Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different level according to the buyers' requirements.
Bars are usually supplied bright in the softened condition.
Final heat treatment - solution treatment.
