MATERIAL TECHNICAL DATA SHEET - ASTM 201
CATEGORY - 17Cr-4Ni Austenitic steel
Mechanical parts used in the condition of corrosion resistance
Bolt and nut
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.
ASTM A959 (2004), A276
Black, Bright - peeled + polishing, centerless grinding
Forged - ring, tube, pipe casing, discs, shaft, flat bar
