TECHNICAL DATA SHEET - S16800

 

CATEGORY - 15Cr-8Ni-2Mo Austenitic steel

 

TYPICAL APPLICATIONS  

Chemical equipments

Mechanical parts used in the condition of corrosion resistance 

Bolts and nuts

 

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.
