NXF UNS S17400/17-4PH/AISI 630 OD DN15-1200 Thickness SCH10-XXS Special Stainless Steel BW LAP JOINT STUB END
The flanged surface of the flanged short section can act as a gasket and perform a sealing function. The application of the flanged short section facilitates the disassembly of specific areas of the pipeline, enabling cleaning, inspection, and quick replacement operations. The size range of the flanged short section is wide, from 1/2" to 24" (DN15 to DN600). The flanged short section has good tensile strength, corrosion resistance, and wear resistance
17-4PH Introduction
Forming
Grade 17-4 stainless steel can be formed mildly.
Welding
Grade 17-4 stainless steel can be welded using common fusion and resistance welding methods. Oxyacetylene welding method is not preferred for welding this alloy.
Heat Treatment
Grade 17-4 stainless steel is soaked at 1038°C (1900°F) for 30 min and cooled below 16°C (60°F) for complete martensite
transformation in the condition A. The condition A material is treated at 482°C (900°F) for 1 h followed by cooling. Solution
treated material is soaked for 4 h at specific temperature in H925, H1025, H1075, H1100, and H1150 conditions followed by cooling in air.
Solution treated material is soaked at 760°C (1400°F) for 2 h in the H1150M condition followed by cooling. It is again heated at620°C (1150°F) for 4 h followed by cooling.
Forging
Grade 17-4 stainless steel is forged at 1010°C (1850°F). Before performing this process, it is soaked at 1177°C (2150°F).
Post-work solution treatment should be performed before final hardening.
Hot Working
Grade 17-4 stainless steel can be hot worked using common processes. It is treated at 1038°C (1900°F).
Post-work solution
treatment should be performed before final hardening.
Cold Working
Grade 17-4 stainless steel can be cold worked using common techniques in spite of its high initial yield strength.
Annealing
Grade 17-4 stainless steel is annealed at 1038°C (1900°F) for 0.5 h followed by cooling rapidly.
Hardening
Grade 17-4 stainless steel has high ductility, and can be formed using all conventional techniques. Powerful equipments are required for forming this alloy because it is stronger than the regular steel. Heavy-duty lubricants are used during cold working.
Applications
Grade 17-4 stainless steel is used in the following applications:
* Nuclear reactor
* Aircraft and gas turbines
* Oil field
* Chemical process components
* Paper mill

Product physical picture
Lap Joint Stub End Produce Processing
1.Raw materials are received and stored in the warehouse.Select the specified specifications of pipes / plates, verify the material certificates and appearance quality, ensuring there are no cracks, corrosion or other defects.
2.Precise cutting and edge trimmingCut the pipes according to the drawing dimensions, remove the excess at the ports, smooth the end faces, and remove burrs and oxide scales.
3.Heating and flanging formingHeat the pipe ports to an appropriate temperature, place them in the special molds for expansion / flanging operations, control the flanging angle and thickness, ensuring a smooth and undistorted appearance without wrinkles.
4.Shaping and fine finishingPerform centering and size correction on the formed parts, smooth the flanging edges, and ensure that the ports are flush and the shape is regular.
5.Inspection and surface treatmentConduct non-destructive testing (UT/MT) to detect internal defects; stainless steel parts need to undergo acid washing and passivation, while carbon steel parts can be treated with rust prevention / painting.
6.Finished product inspection and storageConduct comprehensive inspections of dimensions, appearance and mechanical properties, affix labels, package by category and store in the warehouse, ensuring safe transportation.
