SS 304 Pipe Fittings Supplier in Mumbai, India
Stainless steel 304 fittings are piping components used to join pipes, change flow direction, create branches, and connect different pipe sizes across industrial systems. Rico Steel supplies these ASTM A403 compliant components from Mumbai, India, for contractors, fabricators, and plant engineers.
Grade 304 derives its reliable corrosion resistance from an 18–20% chromium and 8–10.5% nickel chemical composition, forming a self-healing passive oxide film that protects against atmospheric and water-borne degradation without surface coatings. To prevent fabrication issues, fitting schedules must precisely match pipe specifications in grade, nominal bore, schedule, and end preparation.

Types of Stainless Steel 304 Fittings
Common stainless steel 304 pipe fittings include elbows, tees, reducers, crosses, stub ends, couplings and end caps. Each type serves a specific connection, branching, direction-change or pipe termination requirement.
SS 304 Elbow Fittings
Change pipe direction by 45 or 90 degrees and are available in long- and short-radius configurations.
SS 304 Tee Fittings
Create branch connections from a main pipe run, with equal and reducing configurations available.
SS 304 Reducer Fittings
Connect pipes with different nominal sizes using concentric or eccentric designs.
SS 304 Cross Fittings
Create four-way pipe connections where multiple branches meet at one fitting point.
SS 304 Stub Ends
Provide a flanged pipe-end connection when used with a backing flange.
SS 304 Couplings
Join compatible pipe sections where a coupling connection is specified.
SS 304 End Caps
Close the end of a pipe or fitting run and provide a termination point for the piping system.

Stainless Steel 304 Fittings Price List
Nickel content drives the cost of Grade 304, and nickel is volatile, so we quote against current material rates rather than a standing price list.
| Fitting Type | Grade | Size Range | Price |

Applications of Stainless Steel 304 Fittings
Grade 304 is suitable for service where corrosion exposure is moderate and the medium does not carry a meaningful chloride load.
- Food and beverage processing equipment: transfer lines that clean down between production runs.
- Commercial kitchens and food-handling systems: pipework and supports in daily wash-down service.
- Water distribution and utility piping: potable and process water lines that resist rust uncoated.
- Pharmaceutical and selected process installations: piping governed by material compatibility and surface condition.
- Chemical processing applications: media already confirmed compatible with Grade 304.
- Industrial manufacturing and general engineering: plant pipework, compressed air and utility connections.
- Building services and commercial piping systems: services for pipework, utility lines and general commercial piping systems.
- Equipment fabrication and process piping: skid assemblies, vessels and connecting pipework to drawing.
Benefits of SS 304 Fittings
Seven advantages explain why Grade 304 stays the default across general piping.
- Good corrosion resistance: the passive oxide layer performs in atmospheric, water and mild chemical exposure.
- Durability: strength and toughness hold under normal handling and service loads.
- Weldability: standard austenitic procedures and filler apply, with heat input and interpass temperature controlled.
- Availability: configurations, bores and schedules span a wide range.
- Compatibility: 304 fittings can be integrated with compatible austenitic stainless steel 304 piping when the materials and service conditions are properly matched.
- Cleaning and maintenance: smooth surfaces clean down readily in suitable installations.
- Recyclability: full recyclability adds lifecycle value at end of service.
Quality Control and Material Documentation
Predictive testing and validation secure industrial pipe networks from all manner of unauthorized or mismatched fittings. We start with inspections at the grade identification level, rigidly checking chemical composition to avoid the use of lower grade alloys that may be superficially correct but chemically not. Next, we check dimensional tolerances, wall thickness, and end preparations to the appropriate ASME requirements, followed by surface condition. All sales leave with full thermal traceability and certified material test certificates for all of your contract parameters.

FAQs
What are Stainless Steel 304 Fittings used for?
SS 304 fittings join pipe runs, redirect flow, open branches off a header and bridge two bores in industrial piping. Food processing, water distribution, building services, pharmaceutical installations and general manufacturing all specify them.
What types of SS 304 fittings are available?
Elbows, tees, reducers, crosses, stub ends, couplings and end caps are common SS 304 pipe fittings. Availability depends on fitting type, size, specification and current stock.
What is ASTM A403 WP304?
ASTM A403 WP304 identifies a wrought Grade 304 stainless steel fitting manufactured for pressure-piping service under the applicable ASTM requirements. The WP designation identifies the fitting class, while the applicable class and supplementary requirements determine manufacturing and examination requirements.
Are SS 304 fittings suitable for food processing?
Yes, for most food and beverage lines. Grade 304 resists the organic acids and cleaning chemicals common in food plants. Hygienic installations also need the right bore finish, full drainage and a design that cleans down completely.
What information is required to order SS 304 fittings?
Fitting type, nominal bore, schedule or wall thickness, quantity and the governing specification. State the end preparation and any test certificate or inspection requirement at the same time so paperwork matches the order.
