- Stainless Steel Forged Fittings
Midland Alloys Inc. is a leading stainless steel forged fittings manufacturer in India, delivering precision-engineered solutions for industrial piping needs. High-pressure forging is used to shape and heat stainless steel billets to create these fittings, which ensures increased strength and durability. We offer a wide range of forged SS fittings, including elbows, tees, couplings, unions, crosses, and plugs, available in socket weld and threaded types. Our products meet ASTM A182 / ASME SA182 specifications and are available in many grades, including SS 304, SS 316 and SS 316L. Our forged stainless steel fittings meet both functional and visual requirements with surface treatments like pickled, blasted, and mirror shine.
Benefits of Using Werkstoff No 1.4301 SS High-Pressure Forged Fittings
- High Strength and Durability: Forged SS fittings withstand extreme pressure and stress, making them ideal for high-load applications.
- Corrosion Resistance: Grades like SS 304 and SS 316 offer excellent resistance to rust, pitting, and oxidation in corrosive media.
- Leak-Proof Connections: Precision-forged construction ensures tight, secure joints for safe fluid and gas transfer.
- Temperature Resistance: These fittings remain solid in structure in a variety of temperatures, including extreme heat zones, and cryogenic temperatures.

Types of Stainless Steel Forged Fittings
Manufacturing Types
-
Threaded Forged FittingsDesigned with internal or external threads, these fittings allow quick assembly and disassembly without welding.
-
Socket Weld Forged FittingsThese fittings are joined by inserting the pipe into a recessed area of the fitting and welding around it, ensuring strong, leak-proof joints.
-
Screwed FittingsSimilar to threaded types, screwed fittings are connected using screw threads, making installation simple and cost-effective.
-
BSPTBushings help reduce the bore size in a fitting or valve connection by joining pipes of varying diameters.
-
NPTEnd caps are used to seal a pipeline's end, shielding it from impurities and guaranteeing closed systems' safety.
Forms
-
Forged ElbowElbows, which come in 45° and 90° varieties shift the direction of flow with little pressure loss.
-
Forged BushingBushings help reduce the bore size in a fitting or valve connection by joining pipes of varying diameters.
-
Forged TeeUsed to split or combine flow across three directions essential for branching pipeline.
-
Forged CouplingOffer a safe connection between two pipes; threaded and socket-welded options are available.
-
Forged PlugClose open pipe ends which are frequently used for isolation or testing.
-
Forged CrossWith four openings, cross fittings help connect four pipes used when fluid distribution needs to occur in multiple directions.
