NXF UNS S20910 XM-19 OD DN6-DN1200 Pressure 3000-9000lb Special Stainless Steel Forging Fitting Thread Olet
Threaded branch pipes (also known as threaded pipe fittings) are integrally reinforced forged branch pipe fittings manufactured according to MSS SP-97 standards. Unlike butt-welded pipe fittings, their branch pipe ends are machined with standard internal threads (NPT), allowing direct connection to small-diameter threaded pipes without on-site welding. Their arc-shaped base fits tightly to the main pipe surface and features an internal reinforcing structure, effectively reducing structural stress concentration. They are characterized by convenient installation, easy disassembly, and excellent sealing performance.
magneticpermeability of this alloy allows it to be used as a material for medical implants.
Machinability
Stainless steel grade UNS S20910 XM-19 has machinability characteristics that are similar to other austenitic stainless
steels;however it requires slower speeds, more power, and higher rigidity due to its high work hardening rate. It is recommended that coated carbide tooling be used.
Forming
Stainless steel grade UNS S20910 XM-19 can be formed using the same methods applied for other austenitic stainless steels. More power for forming and forging is needed for this alloy. Forging can be done at 1177-1204°C (2150-2200°F).
WeldingWelding of stainless steel grade UNS S20910 XM-19 can be performed using traditional joining processes. Recommended filler metal should be UNS S20910 XM-19 (AWS E/ER209).
Caution should be taken while using autogenous, high power density joining processes such as EB or laser welding, due to low FN potential and severe outgassing possibility.
Heat Treatment
Final annealing process performed for several of the applications, is done at 1065°C (1950°F), which is followed by water
quenching. In case this material is used in a strongly corrosive environment, annealing should be done at 1121°C (2050°F). This alloy cannot be hardened by heat treatment.
Product processing
1. Raw Material Selection: Select high-quality metal alloys, such as carbon steel (e.g., ASTM A105), stainless steel (e.g., F304, F316), or nickel alloys, and test their chemical and mechanical properties.
2. Heating: Heat the raw materials in a furnace (alloy steels are typically heated to above 1200°C) until they become ductile.
3. Forging: Shape the heated metal using a mechanical press or hammer (closed-die forging or open-die forging). This process improves the grain structure and significantly increases the strength of the parts,compared to castings.
4. Heat Treatment: Forgings undergo normalizing, quenching, and tempering processes,to refine the grain structure and achieve the required hardness and toughness.
5. Machining and Threading:Trimming: Remove excess material (flash) using a saw or grinding wheel.
6.Turning and Boring: The connector is machined on a lathe to meet the precise dimensional requirements of MsS SP-9
7.Threading: Internal threads (typically NPT conforming to ASME B1.20.1) are machined at the internal outlet for branch pipe connection.6. Inspection and Testing: The finished outlet undergoes dimensional inspection and non-destructive testing (NDT), such as ultrasonic or magnetic particle testing, to detect any internal defects.
