MATERIAL CATEGORY - 11Cr-Ni-Ti Ferrite type
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 annealed condition.
Final heat treatment - solution treatment / QT
MATERIAL SPECIFICATIONS - ASTM A959 (2004), A276, A312, A632, A176,
A580
AVAILABILITY
Round bar / flat bar / steel strip / square bar / ring / plate /
valve body
Bright - peeled + polishing, centerless grinding
Forged - ring, tube, pipe casing, discs, shaft

HEAT TREATMENT PRACTICE
Heat treatment is only suitable for specific grades of
stainless steel. When heat treating a stainless the hardening temperatures,
including rate of heating, cooling and soaking times will vary due
to several factors such as the shape and size of each component.
Other considerations during the heat treatment process include the
type of furnace, quenching medium and work piece transfer
facilities. Please consult with the heat treatment provider for
whole guidance on heat treatment of stainless steel grades. We are
delighted to help to work with you the special heat treatment based
on your special requirements.
