Lub rooj zaum ntawm cov nplaim hluav taws xob ntub dej: 316L EP vs . 904} l tshuaj tua

 

Vim li cas 316L-ep npog 90% ntawm ntub lub rooj ntev zaum?
Electropolishing rau ra 0.15μm kev txwv me me ua rau<5/ft³ >0 {. 1μm. Ntawm HF / TNO₃ Sib MixTures ntawm 60℃nrog<0.01mm/year corrosion. Costs $350/kg vs. 904L's $850/kg.

 

Thaum 904L yog qhov yuav tsum tau ua rau cov kev ua haujlwm siab?
Rau<5nm nodes processing copper interconnects with HCl/H₂O₂ mixtures. Molybdenum (4.5%) prevents pitting from chloride residuals. Surface iron content <0.001% prevents electroplating defects.

 

Qhov siab tshaj plaws uas tau tso cai rau cov khoom tsis muaj kuab?
Kev Hloov Cov Hlau<1E10 atoms/cm². Particles >0.05μm <0.1/mL. Organic residues <5ng/cm². Surface roughness Rz <0.5μm after 500 cleaning cycles.

 

Qhov tseem ceeb vuam specifications?
Orbital GTAW nrog ER316LSI muab tub lim rau hauv cov tsev pheebsuab sib cav (O₂<10ppm). Internal purge until weld cools below 100°C. Electropolishing removes 15μm post-weld.
