Specifications AISI 309S datasheet, AISI 309S Chemical, AISI 309S Properties from Steelmelting (ESR refined), Blooming, Hot forging, Hot rolling, Heat treatment, Straightening, 100% Ultrasonic flaw detection test, Cold working or Machined. All of these materials conform to Military standard, nuclear power. 100% Ultrasonic test ASTM E2375 /SAE AMS 2154 /SEP 1923 /GB/T 4162 /EN 10228-3.
MATERIAL TECHNICAL SPECIFICATION - GRADE AISI 309S
MATERIAL CATEGORY - 23Cr-14Ni Austenitic steel
PRODUCT DESCRIPTION
The alloy is usually produced by AOD / VOD / VIM followed by electroslag refining (ESR) / VAR if necessary for special purpose.
Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different levels according to the buyers' requirements.
Bars are usually supplied black/bright in the softened condition.
Final heat treatment - solution treatment / QT
