Description 1.4122 Round bar, Ex-stock 1.4122 Steel coil, Sheet 1.4122 Forgings Properties from Steelmelting (ESR refined), Blooming, Hot forging, Hot rolling, Heat treated
TECHNICAL DATA SHEET - W-Nr 1.4122
MATERIAL CATEGORY - Martensitic and precipitation hardening corrosion resisting steels
PRODUCT DESCRIPTION
The alloy is usually produced by AOD / 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 bright in the annealed condition.
Final heat 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.
