Product Description
UNS S20910 XM-19 Stainless Steel Introduction
UNS S20910 XM-19 Stainless Steel Introduction
UNS S20910 XM-19 stainless steel is an austenitic stainless steel with a blend of strength and corrosion resistance that is higher than stainless steel grades 316, 316/316L, 317, and 317/317L .The high strength, corrosion resistance, and low
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).
Welding
Welding 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.

Hex Head BushingIntroduction
Hex Head BushingIntroduction
A hex head bushing is a cylindrical mechanical connector with a hexagonal head and a threaded inner hole. It is also often called a hexagonal internal/external thread bushing or a hexagonal reducing bushing. It is a core hardware component used for transition connections, diameter changes, positioning, and sealing in industrial pipelines and equipment assembly, and is widely compatible with various thread specifications of pipelines and equipment interfaces.

Hex Head Bushing Produce Processing
1. Material Preparation & InspectionSelect solid round bar as raw materialCheck surface quality, straightness and diameter of the round barEnsure no cracks, defects or inclusions before processing2. Cutting & BlankingAutomatic sawing or CNC cutting to fixed lengthReserve machining allowance for length and diameterEnsure flat end faces without burrs or deformation3. CNC Turning (Rough Machining)Clamp workpiece in CNC latheFace both ends to ensure flatnessRough turn outer diameter and hexagonal blankDrill and bore center hole, reserve allowance for internal threading4. External Thread MachiningPrecision CNC thread turning or thread rollingForm standard external threads (metric, BSP, NPT, etc.)Control thread pitch, diameter and toleranceCheck with thread gauges for fitting accuracy5. Internal Thread MachiningPrecision tapping or CNC internal threadingEnsure full-depth, uniform internal threadMaintain high coaxiality between inner hole and outer thread100% inspection with thread plug gauges6. Hex Head Forming
Method 1 (high precision): Milling on CNC turning-milling machineMethod 2 (mass production): Forging / heading processForm standard hexagonal shape with accurate flat-to-flat sizeEnsure stable structure for wrench installation7. Chamfering & DeburringChamfer thread ends (usually 45°) for easy assemblyRemove sharp edges, burrs and machining chipsSmooth all surfaces to avoid scratching or damage during installation8. Surface TreatmentOptional: Polishing, brushing or other surface finishing processesClean oil, coolant and contaminants from surface and threads9. Final Quality ControlDimensional inspection: length, outer diameter, hex size, thread toleranceCoaxiality and concentricity testingAppearance check: no scratches, cracks, deformation or defectsRandom sampling inspection for overall quality10. Packaging & WarehousingAnti-collision and protective packagingSort by size and specificationPack into cartons or storage boxesLabel clearly for delivery and inventory man
