Technical specifications of AISI 18Ni & Maraging 300 Stainless steel round bar, Plate AISI Grade 18Ni Maraging 300 Forgings, Hot rolling, heat treatment
MATERIAL DATA SHEET - 18Ni & Maraging 300
MATERIAL CATEGORY: 18% Nickel and Cobalt strengthened steel
PRODUCT DESCRIPTION
The alloy is usually produced by 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 / Q+T.

Maraging 300 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.
The density of maraging 300 steel is 8.0 g/cm3.

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.
