Stainless Steel Pipe Fittings
Stainless steel pipe fittings are joining parts that are used to switch direction, branch lines, decrease size or close piping systems. They are chosen where piping must resist corrosion, maintain temperatures and offer predictable pressure behavior. Fittings used in process plants and utility piping are chosen to fit the grade of the pipes and the standard applicable in their dimensions.
Aashish Metals is a manufacturer and supplier of stainless steel pipe fittings that cater to the needs of industrial procurement and project. The selection of materials is in accordance with the conditions and requirements of the service, and confirmation of the grades, documentation, and coordination of inspection is done prior to dispatching to mitigate the risk of misalignment.

Chemical Composition of Stainless Steel Pipe Fittings
Chemical composition depends on the selected grade and the governing material standard. For procurement control, the practical check is the grade designation and the UNS number shown on the MTC, supported by heat number traceability.
| Grade supplied on this page | Common UNS designation |
|---|---|
| Stainless Steel 310 | UNS S31000 |
| Stainless Steel 310S | UNS S31008 |
| Stainless Steel 317 | UNS S31700 |
| Stainless Steel 317L | UNS S31703 |
| Stainless Steel 347 | UNS S34700 |
| Stainless Steel 347H | UNS S34709 |
| Stainless Steel 904L | UNS N08904 |
Mechanical Properties of Stainless Steel Pipe Fittings
Mechanical properties are verified on the supplied heat through the Mill Test Certificate. Values depend on grade, product form, and heat treatment condition. For project submittals, the relevant control points are tensile strength, yield strength, elongation, and hardness reported on the MTC.
| Property verified for stainless steel fittings | How it is typically confirmed |
|---|---|
| Tensile strength | Reported on MTC for supplied heat |
| Yield strength | Reported on MTC for supplied heat |
| Elongation | Reported on MTC for supplied heat |
| Hardness where applicable | Reported on MTC or inspection requirement |
| Heat treatment condition | Reported on MTC where applicable |

Applications of Stainless Steel Pipe Fittings
SS pipe fittings in grades 310, 317L, 347H, and 904L are commonly specified where piping must handle heat, corrosion, or aggressive media while maintaining long term joint reliability.
Typical application areas include:
- High temperature process lines and furnace related piping
- Chemical processing and corrosive fluid handling systems
- Refinery and petrochemical piping assemblies
- Heat exchanger, condensate, and utility piping
- EPC projects requiring documented material traceability
Why Source Stainless Steel Pipe Fittings from Aashish Metals
Aashish Metals is a controlled supplier of stainless steel piping systems in which flaws in grades and lack of documentation result in rework during the fabrication and inspection processes. Prior to dispatch, grade and standard alignment is checked against the purchase requirement, the fitting specification reference and end connection type. This favors procurement teams that require regular material tracing and foreseeable documentation to approvals.
High temperature grades, 310, 310S, stabilized grades, 347, 347H, and corrosion resistant grades, 317L and 904L are supplied on this page. In case of similarity of the material in pipes, fittings are also positioned to be in line with the related piping grade to ensure that the piping class remains the same in documentation and on site installation.
