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.

Lap Joint Stub End Introduction
Lap Joint Stub End Introduction
Flange-fitting short sections are core connectors for clean fluid transport pipelines in the food, pharmaceutical, and bioengineering industries. This component mainly consists of a circular end with a chuck flange and a smooth cylindrical section. The cylindrical section is welded for fixation, while the chuck end allows for tool-free quick assembly and disassembly using matching clamps and food-grade sealing gaskets. The main body is typically made of 304 or 316L stainless steel, with a high-precision polished inner wall resulting in extremely low surface roughness. The overall design eliminates any unsanitary dead corners, effectively preventing media residue and adapting to CIP (clean-in-place) and SIP (sterilization-in-place) process requirements. It also possesses excellent acid and alkali resistance, high-temperature resistance, and reliable sealing properties, making it widely used in fluid transport scenarios with stringent hygiene requirements, such as those in the dairy, beverage, pharmaceutical, and fine chemical industries.

Lap Joint Stub End Produce Processing
Lap Joint Stub End Produce Processing
1.Raw Material Selection and Pre-treatment: 304/316L stainless steel bars/tubes conforming to ASTM standards are selected. Upon arrival at the factory, spectral composition and mechanical property tests are conducted to ensure material compliance. Subsequently, surface oxide scale and impurities are removed through sandblasting and pickling, completing the raw material pre-treatment.2.Precision Blanking and Forming: According to product specifications, the raw material is precisely blanked using a CNC sawing machine, and then hot forging, cold heading, or spinning processes are used to integrally form a joint blank with a chuck flange, ensuring structural strength and dimensional accuracy, and avoiding hygiene hazards caused by weld gaps.3.Machining and Finishing: Precision machining of the inner hole, outer diameter, and chuck end face is performed using CNC lathes and milling machines, strictly controlling dimensional tolerances and coaxiality. Simultaneously, chamfering is performed at the joints to eliminate burrs, preparing for subsequent polishing processes.4.High-precision polishing of inner and outer walls: First, rough polishing and semi-fine polishing remove machining marks, followed by mirror polishing to control the surface roughness of the inner wall to Ra≤0.4μm (Ra≤0.2μm for pharmaceutical grade), ensuring no unsanitary corners and no media residue, meeting clean transport requirements.5.Passivation and surface treatment: The polished joint is immersed in a special passivation solution to form a dense oxide protective film on the surface, significantly improving the corrosion resistance of the stainless steel. Degreasing and cleaning are then performed to remove surface oil and chemical residues.6.Non-destructive testing and quality control: Sealing performance is tested using water pressure/air pressure testing. Eddy current testing and penetrant testing are used to check for internal cracks and defects. Simultaneously, dimensions, roughness, and material are fully re-inspected to ensure the product meets industry standards such as 3A and GMP.7.Clean packaging and shipping: Final cleaning and drying are completed in a cleanroom. Food-grade dust-free packaging is used for sealing to avoid secondary contamination. Material certificates and test reports are included before shipping.
