PRODUCT DESCRIPTION
The
The
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
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
Wrought Ni-Cr alloy strengthened by the addition of Ti and Al. Age hardenable and creep-resistant alloy for service at temperatures to 920°C.
Density 8.18 gm/cc
Melting point: 1370 °C
HEAT TREATMENT PRACTICE
Annealing - Age Harden at 750°C (1380°F) for 4 hours and air cool.
Annealing - Age Harden at 750°C (1380°F) for 4 hours and air cool.
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.
