ASTM A276 Material Specification Corrosion Resistant Steel S31260 Round bar, flat bar, plate and wire forgings S31260 Stock Available Heat treatment
TECHNICAL DATA SHEET - UNS S31260
MATERIAL CATEGORY: 25Cr-6Ni-3Mo-W-Cu-N Austenite-Ferrite type alloy 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 annealing (+ AT).

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.
