18Cr-Ti Ferrite type AISI 439 Plate, Flat bars Ex-stock AISI 439 Inventory Wire rod Steel melting (ESR refined), Blooming, Hot forging, Hot rolling, Heat treatment, Cold machined.
MATERIAL TECHNICAL DATA SHEET - AISI 439 / AISI XM-8 / S43035
MATERIAL CATEGORY: 18Cr-Ti Ferrite type
PRODUCT DESCRIPTION
The alloy is usually produced by AOD / EAF / VOD 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

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.
TYPICAL APPLICATIONS
