SS 2324/AISI 329/UNS S32900/1.4460 Forged Forging Hollow Bars Honed Ba Duplex Steel

1.4460 (AISI 329 – SS2324)

By using 1.4460 (AISI 329 – SS2324) you get an acid resistant stainless steel designed for machining. The steel has excellent corrosion properties and is used e.g. to propeller shafts, pump shafts and piston rods.

The steel grade 1.4460 ( also called AISI 329 and SS2324) is a stainless, acid resistant, duplex steel with improved machinability. Since the steel is machinability improved, it is suitable for production of details with comprehensive machining. The steel has very good corrosion resistance particulary in chloride-bearing environments and is extra resistant to pitting corrosion, crevice corrosion, stress corrosion cracking and corrosion fatigue. It also has high strentgth and toughness.

Som typical applications areas for 1.4460 are:

• Propeller- and Pumpshafting
• Pump- and Valveparts
• Pistons
• Stirrers
• Bolts
• Nuts

Good machinability, weldability and formability
1.4460 is possible to weld and do not need to be welded with welding consumables similar to that of the parent one. The steel shall be welded as austenitic material with as low heat input as possible. It can be both cold- and hot formed. The steel is easier to machine and it has significantly better machinability, but slightly worse corrosion resistance than 1.4462.

Certificate
The steelworks has certificate as an approved material supplier of this steel grade from ABS, BV, DNV, GL, Lloyd’s and RINA.

We offer steel grade 1.4460 in the following profiles

Steel grade 1.4460 is available as machined round bar and ground round bar. It is available in dimensions 8 – 310 mm depending on profile and execution.

※ 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 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.
