ASTM B111 C61300 Copper Qws / Tube: Corrosion thiab Fatigue Resistance

ASTM B111 Copper Tube PDF

Core Performance Advantages
Zoo heev Corrosion Resistance
Seawater Corrosion Resistance: Kev ua tau zoo nyob rau hauv marine ib puag ncig, tiv thaiv ntsev tsuag, yaig corrosion, thiab biofouling, nrog lub neej ntev tshaj li ntawm cov tooj liab zoo tib yam.
Tshuaj tiv thaiv corrosion: Muaj zog tiv thaiv rau dilute sulfuric acid, alkaline daws, thiab cov organic media, tshaj li feem ntau tooj liab alloys (xws li tin bronze).
Dealuminization Corrosion Resistance: Uniform faib ntawm txhuas cov ntsiab lus tiv thaiv ib cheeb tsam xaiv corrosion.

Sab saum toj -notch Fatigue Resistance
Corrosion Fatigue Resistance (Core Advantage): Nyob rau hauv cov xwm txheej ntawm corrosive media thiab alternating stress (xws li propeller shafts thiab yoj- cuam tshuam cov Cheebtsam), qaug zog lub neej yog 2-3 npaug ntawm zoo tib yam stainless hlau.
Siab Fatigue Strength: Tom qab kev kho cua sov (xws li quenching thiab tempering), qhov kev qaug zog tuaj yeem ncav cuag 250-300 MPa (ntau dua C61000). Stress Corrosion Cracking (SCC) Resistance: Siab tiv taus rau qhov chaw rhiab heev xws li chlorides.

Balanced zog thiab toughness
Tensile Strength: Ntau dua los yog sib npaug rau 690 MPa (kub-kho), Yield Strength Ntau dua lossis sib npaug li 620 MPa, nce qib siab - lub zog alloy steels.
elongation: 8-15%, tuav zoo ductility kom tsis txhob nkig puas.

Cavitation Resistance

Kev tiv thaiv zoo heev rau kev sib tsoo nyob rau hauv qhov cuam tshuam ntawm cavitation vau los ntawm kev siab - kua ntws ceev (xws li hauv cov twj tso kua mis thiab cov turbine hniav).

Marine Engineering:
Propeller Shafts (Core Application): Siab torque, seawater corrosion, thiab alternating bending stresses.
Rudder Stocks thiab Stern Shafts: Tau txais kev cuam tshuam cov loads thiab corrosion qaug zog.
Siab -Lub Zog Fasteners: Steering Iav Bolts thiab Subsea Valve Bolts (yuav tsum muaj corrosion thiab kev co kuj).

Cov Khoom Siv Hluav Taws Xob:
Turbine Main Shafts: Dej ntws cuam tshuam thiab corrosion qaug zog. Sib sib zog nqus- lub twj tso kua mis zoo: Yuav tsum muaj kev tiv thaiv corrosion, hnav tsis kam, thiab qaug zog ua haujlwm.

Cov khoom siv tshuaj:
Siab -siab valve stems (corrosive media + nquag qhib thiab kaw lub voj voog loads).
Agitator shafts (kev vibration loads hauv corrosive slurries).

Offshore platform hydraulic piping:Kev qaug zog lub neej yuav tsum muaj rau siab - cov kav dej siab hauv cov tshuaj tsuag ntsev.

Nkoj txias system piping:Seawater txias kav yuav tsum tiv thaiv corrosion corrosion thiab kev co qaug zog.

High-stress heat exchanger tubes:Yuav tsum tau ib txhij thermal conductivity, siab tsis kam, thiab qaug zog tiv thaiv rau media corrosion.

C61300 yeeb nkab yog cov khoom siv zoo tshaj plaws rau kev hais txog ob qho -kev ua "corrosion + qaug zog", tshwj xeeb tshaj yog haum rau:
Nkoj propulsion systems (shafting, propellers);
Hydraulic / seawater twj core rotating Cheebtsam;
Hydraulic kis tau tus mob nyob rau hauv siab -kev nyuaj siab corrosion ib puag ncig.
