AVAILABILITY:-
- Seamless Pipe 1/2" W
SPECIFICATION:-
- ASTM B677, B366
- ASME SB677, SB366
DESCRIPTION:-
904L is a high-alloy austenitic stainless steel with low carbon content. The grade is intended for use under severe corrosive conditions. It has been application proved over many years and was originally developed to resist corrosion in dilute sulfuric acid. It is standardized and approved for pressure vessel use in several countries. Structurally, 904L is fully austenitic and is less sensitive to precipitation ferrite and sigma phases than conventional austenitic grades with high molybdenum content. Characteristically, due to the combination of relatively high contents of chromium, nickel, molybdenum and copper 904L has good resistance to general corrosion, particularly in sulfuric and phosphoric conditions.
DESIGN FEATURES:-
- Good resistance to pitting and crevice corrosion.
- Very good resistance to stress corrosion cracking.
- Good resistance to intergranular corrosion.
- Good formability and weldability.
- Maximum service temperatures of 450 deg.C. (824 deg.F).
TYPICAL APPLICATIONS:-
- Production and transport of sulfuric acid
- Metal pickling in sulfuric acid
- Production and concentration of phosphoric acid
- Use in seawater, brackish water, condensers, heat exchangers and pipe work in general
- Paper and allied industries
- Gas washing
- Chemical and pharmaceutical industries
TENSILE REQUIREMENTS:-
- Tensile Strength (KSI) 70
- Yield Strength (KSI) 25
- KSI can be converted to MPA (Megapascals) by multiplying by 6.895.

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. |
