Yintoni i-SAF2205?

I-SAF2205 ludidi oluqhelekileyo lwentsimbi engagqwaliyo ephindwe kabini eyenziwe yiSandvik, ekuqaleni ithetha iSandvik Austenite Ferrite. Iyaziwa ngamandla ayo aphezulu kunye nokumelana okuhle kakhulu nokugqwala kwe-chloride stress, kwaye ithathwa njengesixhobo sokukhuselaumjelo wamanziizixhobo zokuphucula ukusuka kwiintsimbi eziqhelekileyo ezingenasici ezifana ne-316L ukuya kwiintsimbi ezingenasici ezingenasici. Ukwahluka kwayo kukwisakhiwo sayo sangaphakathi, esimalunga nesiqingatha se-ferrite kunye nesiqingatha se-austenite, sidibanisa iingenelo zezakhiwo ezincinci zombini.

Ukusebenza kwe-SAF2205 kunokuthelekiswa ngokuthe ngqo ne-benchmark 316L esetyenziswa rhoqo ngolu hlobo lulandelayo:

• Amandla:Malunga ne-450 MPa, ephindwe kabini kune-316L, nto leyo evumela ukuba udonga lube lukhuni ngakumbi.
• Ukumelana nokugqwala (ixabiso le-PRE):≥35, iphezulu kakhulu kune-316L's 24. Inokumelana okunamandla kakhulu nokugqwala kwemingxuma kunye nemingxunya kwiindawo ezine-chloride (ezifana namanzi olwandle).
• Ukuqhekeka koxinzelelo lokugqwala:Igqwesile. Kwiindawo ezine-chloride, i-316L ithanda ukuqhekeka kumaqondo obushushu angaphezu kwama-60°C, ngelixa i-SAF2205 inokumelana okuhle kakhulu.

I-SAF2205 ineempawu ezahlukeneyo ezifanayo. Nceda uqaphele umahluko xa uthenga:

• I-UNS S31803:Ibanga lokuqala.
• I-UNS S32205:Umgangatho wanamhlanje nosetyenziswa kakhulu onolawulo olungqongqo malunga nokwakheka (ingakumbi i-nitrogen), kunye nokumelana nokugqwala okungcono kune-S31803 yodidi oludala.
• EN 1.4462:Ukubekwa phantsi komgangatho we-EU.

Ngokudityaniswa kwe"Amandla aphezulu + ukumelana nokugqwala", idla ngokusetyenziswa endaweni ye-316L ukujongana neemeko zokusebenza ezinzima ngakumbi:

• Ishishini le-petroleum kunye neekhemikhali:izitshintshi zobushushu, imibhobho, imikhumbi yoxinzelelo, ezilungele ngakumbi iindawo eziqulethe ii-ion ze-chloride kunye ne-hydrogen sulfide.
• Ubunjineli bolwandle:izixhobo zokukhupha ityuwa emanzini olwandle, izinto zokwakha iinqanawa, ezimelana nokugqwala kwamanzi olwandle.
• Ushishino lokwenza amaphepha kunye neekhemikhali:iimbiza zokupheka, izixhobo zokublisha, izixhobo ze-PTA (i-purified terephthalic acid), njl.
• Iimeko ezikhethekileyo:ingasetyenziselwa ukwenza izipringi ezisebenza kakuhle (-100 ukuya kwi-300℃ iyasebenzaokanye izixhobo zamazinyo.
