Product Description
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.

Threaded Straight Hexagonal Nipple Produce Processing
1. Raw Material Preparation
Adopt high-quality 304/316 stainless steel seamless pipes/round bars as raw materials.
Conduct material inspection: chemical composition test, hardness test and surface defect detection to ensure corrosion
resistance and pressure resistance.

resistance and pressure resistance.
2. Cutting & Blanking
Use automatic CNC cutting equipment to cut raw materials into fixed-length blanks according to product specifications.
Ensure flat cutting section, no burrs and strict dimensional tolerance control.
3. Hexagonal Forging / Machining
Process the middle part into a standard regular hexagonal prism (wrench position) by cold forging or CNC lathe machining.
Guarantee equal side length, sharp edges and flat surface, which is suitable for standard wrench clamping.
4. Internal Boring & Hollow Forming
Perform precision boring on the inner hole to form a full through hollow structure.
Polish the inner wall to ensure smooth surface, no impurities, low fluid resistance and no blockage.
5. External Thread Turning
Use high-precision CNC lathes to machine full continuous external threads at both ends.
Strictly control thread pitch, tooth profile and depth; no missing teeth, no smooth cylindrical section, and perfect matching
with standard female thread fittings.
6. Deburring & Surface Finishing
Remove all sharp edges, burrs and machining residues inside and outside the product.
Conduct surface polishing treatment to present uniform metallic luster, no scratches and no oil stains.
7. Dimension & Quality Inspection
Full inspection of thread accuracy, outer diameter, inner diameter, hexagonal size and overall length.
Air tightness test and pressure resistance test to ensure zero leakage in pipeline connection.
8. Cleaning & Packaging
Ultrasonic cleaning to remove cutting fluid and dust; anti-rust treatment.
Neutral packaging (no logo/text) or customized packaging, suitable for warehouse storage and international transportation.
Ensure flat cutting section, no burrs and strict dimensional tolerance control.
