UNS S20103 - DATA SHEET
17Cr-4Ni 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.
MATERIAL SPECIFICATIONS
. ASTM A959 (2004), A276
AVAILABILITY
Black
Bright - peeled + polishing, centerless grinding
Forged - ring, tube, pipe casing, discs, shaft, flat bar
