MATERIAL DATA SHEET - DIN X8CrNiS18-9 / W-Nr 1.4305
MATERIAL CATEGORY - Austenitic corrosion resisting steels
PRODUCT DESCRIPTION
The alloy is usually produced by AOD / EAF 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

Maraging steels are iron-nickel alloys with absence of carbon and have metals such as molybdenum, cobalt, titanium and aluminum.
The alloys have ultra-high strength, superior toughness characteristics and weldability. Typically, these alloys are used in aerospace applications, machinery and tooling and ordnance components and fasteners.

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.
