S31803 Yeeb Nkab Core Performance

uns s31803 yeeb nkab Corrosion Resistance

S31803 yeeb nkab muaj qhov zoo tagnrho corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv corrosive ib puag ncig uas muaj chlorides thiab hydrogen sulfide. Nws tsis kam mus rau kev ntxhov siab corrosion cracking yog superior rau qhov zoo tib yam austenitic stainless hlau xws li 304L thiab 316L. Nyob rau tib lub sijhawm, cov qauv duplex thiab cov ntsiab lus carbon tsawg muab nws zoo ua haujlwm rau intergranular corrosion. Cov cua sov- cuam tshuam thaj tsam tom qab vuam tuaj yeem rov ua dua- ua rau theem austenitic, txo qhov kev pheej hmoo ntawm carbide thiab nitride nag lossis daus ntawm cov ciam teb nplej.

 

s32205 yeeb nkab Mechanical Properties

Lub zog tawm los ntawm S31803 yeeb nkab yog kwv yees li ob npaug ntawm cov hlau tsis zoo austenitic, feem ntau ncav cuag 400-550 MPa. Lub zog siab no tso cai rau cov yeeb nkab phab ntsa thicknesses hauv kev tsim, yog li txo cov khoom hnyav thiab tus nqi. Cov yeeb nkab kuj muaj qhov cuam tshuam zoo thiab tuaj yeem tiv taus qhov kub ntawm -50℃F txog 600℃F (kwv yees li -45℃txog 315 degree). Cov ntawv thov uas muaj cov qauv welded sab nraum qhov ntsuas kub no yuav tsum tau ua tib zoo soj ntsuam.

 

s31803 tubing vuam thiab kev ua tau zoo

S31803 yeeb nkab muaj qhov zoo weldability, yuav tsum tsis muaj preheating ua ntej vuam thiab feem ntau tsis muaj kev kho cua sov tom qab. Kev pom zoo vuam txoj kev suav nrog phau ntawv hlau arc vuam (MMA / SMAW) thiab roj shielded arc vuam, nrog tungsten inert gas welding (TIG / GTAW) yog txoj kev nyiam. Thaum lub sij hawm vuam, nws raug nquahu kom tswj cov cua kub nkag mus rau 0.5-2.5 kJ / mm, thiab qhov kub ntawm qhov sib cuam tshuam yuav tsum qis dua 150℃(300℃F).

 

S31803 Pipe Application

Petrochemical Kev Lag Luam:Roj zoo drilling kav dej, roj thiab roj xa cov kav dej, cov cua kub exchanger raj rau cov khoom siv refining

Seawater Desalination Projects:Seawater kis pipelines, desalination khoom Cheebtsam

Kev lag luam fais fab:Fais fab cog condenser raj, boiler piping

Municipal Engineering:Kev kho cov kav dej phwj tuaj, cov kav dej xa dej tom qab desalination

Lwm tus:Corrosion-cov kav dej tiv taus rau metallurgy thiab mining, cov khoom siv ua zaub mov, cov kav dej kho mob, thiab lwm yam.
