GENERAL PROPERTIES:-
Alloy 330 is an austenitic, nickel-chromium-iron-silicon alloy that has outstanding resistance to oxidation and carburization up to 2200°F with high strength. The excellent resistance to oxidation and carburization is provided by the high nickel and chromium content of the alloy, further enhanced by its silicon content. Alloy 330's ultra high nickel content of 34 to 37% also provides high resistance to chloride stress corrosion cracking and embrittlement from the precipitation of sigma phase in most furnace atmospheres. Alloy 330 also has a low coefficient of expansion, excellent ductility, and high strength.
APPLICATIONS:-
Alloy 330 is extensively used in high temperature environments where resistance to the combined effects of thermal cycling and carburization is necessary. Applications include:
- Chemical and Petrochemical Processing: cracked ammonia components, petrochemical furnace parts, heat exchangers, flares, etc
- Thermal Processing: heat-treat furnace containers & compartments, high temperature fans, salt pots, etc
- Ore Processing: perlite system and equipment
- Power Generation: boiler fixtures, gas turbine components, etc

CORROSION RESISTANCE:
- Provides high level of corrosion resistance especially with regards to oxidation, carburization, and nitridation
- Has great oxidation resistance and resists scale formation up to about 2000°F due to its chromium and nickel content
- Excellent resistance to carburization due to its 34 to 37% nickel and silicon content
- Exhibits resistance to nitrogen containing atmospheres where the oxygen content is low
- High nickel content also makes it highly resistant to chloride stress corrosion cracking and sigma phase embrittlement
HARDENING:-
- Alloy 330 will not respond to heat treatment; will only harden upon cold work
MACHINABILITY:-
- Rigid mounts, sulfurized lubricants, positive feeds and slow speeds are recommended for machining grade 330 stainless steel.
WELDING:-
- Grade 330 stainless steel can be welded using GAW techniques.
HOT WORKING:-
- Hot working of grade 330 stainless steel can be performed at 1149 to 1177°C (2100 to 2150°F).
COLD WORKING:-
- It is difficult to perform cold working in grade 330 stainless steel as the steel has high strength and work hardening rate. However, this steel can be cold worked using strong forces.
ANEALING:-
- Grade 330 stainless steel can be annealed at 1121 to 1204°C (2050 to 2200°F).

Fittings and Flanges for Stainless Steel Pipe
Stainless steel piping systems can be joined by butt welding and, in the heavier 40S and 80S schedules, with threaded connections.
BUTT WELDING STAINLESS STEEL PIPE FITTINGS
Harsh steel stocks butt welding fittings in the following configuration.
- Elbows 45 degree and 90 degree - long radius and short radius.
- Return bends 180 - long radius and short radius.
- educers - concentric and eccentric.
- Tees - equal and reducing.
- Caps.
- Stub ends - Type B.
Advantages of stainless steel butt Weld fitting to the pipe are to keep pipes permanently leak proof. The continuous structure helps strength between pipes and fittings. It reduces pressure and also minimises the action of corrosion and erosion. Butt welding fittings can be supplied in either seamless or welded construction and are covered by specifications ASTM A403M and ASTM A815M for Duplex grades.
STAINLESS STEEL SCREWED AND SOCKET WELD FITTINGs
Stainless steel piping systems can be connected using stainless steel screwed fittings - BSP threaded ("150lb") low pressure stainless steel fittings and NPT class 3000 high pressure stainless fittings in Grade 316. Socket weld fittings are used in high pressure piping systems and available in grade 316L to suit schedule 80S wall thickness piping.
MANUFACTURING SPECIFICATIONS:
- ASTM A182M (3000lb NPT and socket weld).
- ANSI B16.3 (BSP dimensions)
- ISO 4144 (BSP dimensions)
STAINLESS STEELS FITTINGS AND FLANGES:
A flange is a ring of steel (forged, cut from plate, or rolled) designed to connect sections of pipe, or to join pipe to a pressure vessel, valve, pump or other integral flanged assembly. Flanges are joined to each other by bolts, and to the piping system by welding or threading (or loose when stub ends are used). Forged stainless steel flanges are designed to the following common pressure ratings, stainless steel flanges are exported by Harsh Steel in Classes 150, 300, 600, 900, 1500 and 2500. Standard sealing face is Raised Face (RF).
The basic types of flanges are:
- Stainless steel slip-on flange
- Stainless steel socket weld flange
- Stainless steel blind flange
- Stainless steel lap joint flange
- Stainless steel weld neck flange
- Stainless steel threaded flange
- Stainless steel orifice Flange
Manufacturing specification: ASTM A182M
Plate stainless steel flanges are cut and machined from plate - Table 'D', Table 'E', etc.
Manufacturing specification: AS2129.
Types and applications of Stainless steel and Nickel alloy flanges
| Slip-on flanges | The flange is slipped over the pipe and then welded both inside and outside to provide sufficient strength and prevent leakage. Slip-on flanges are also used as loose back-up flanges when stub ends are used. |
| Blind flanges | This is a flange without a centre bore, used to shut off a piping system or vessel opening |
| Weld neck flanges | This is a flange without a centre bore, used to shut off a piping system or vessel opening |
| Lap joint flanges | This is again similar to a slip-on flange, but has a radius at the intersection of the centre bore and the flange face to accommodate a lap stub end. |
