Iipleyiti zeStainless Steel 321/321H

Ingxubevange ye-321 (i-UNS S32100) izinzile ipleyiti yensimbi engenasici enika njengeyona nzuzo iphambili ukuxhathisa kwi-intergranular corrosion kulandela ukuvezwa kwamaqondo obushushu kwi-chromium carbide precipitation range ukusuka kwi-800 ukuya kwi-1500°F (427 ukuya kwi-816°C). I-alloy 321 ipleyiti yensimbi engenasici izinzile ngokuchasene nokwakheka kwe-chromium carbide ngokongezwa kwe-titanium.

I-alloy 321 ipleyiti yensimbi engenasici nayo inenzuzo kwinkonzo yobushushu obuphezulu ngenxa yeempawu zayo ezilungileyo zoomatshini. I-alloy 321 ipleyiti yensimbi engenastainless inikezela ngepropathi ephezulu kunye nokuqhawuka koxinzelelo kuneAlloy 304 kwaye, ngakumbi, iAlloy 304L, enokuthi kananjalo iqwalaselwe ukuba sesichengeni apho uvakalelo kunye ne-intergranular corrosion ziyinkxalabo.

Ukuqulunqwa
Uhlobo lwe-321 lunokwenziwa lula kwaye lutsalwe, nangona kunjalo, uxinzelelo oluphezulu luyafuneka kwaye i-springback eninzi ifunyenwe kune-carbon steel kunye ne-ferritic stainless steels. Njengezinye iintsimbi ze-austenitic stainless, udidi lwe-321 lusebenza ngokukhawuleza kwaye lunokufuna ukuhlanjululwa emva kokubunjwa okukhulu.

Unyango lobushushu
Uhlobo lwe-321 alunakunyanzeliswa ngonyango lobushushu.I-Annealing: Ukufudumala ukuya kwi-1750 - 2050 °F (954 - 1121 ° C), emva koko kucinywe amanzi okanye umoya upholile.

Ukuweldability
Iklasi ye-austenitic yeentsimbi ezingenasici ngokuqhelekileyo ithathwa njenge-weldable yi-fusion eqhelekileyo kunye neendlela zokumelana. Uqwalaselo olukhethekileyo luyafuneka ukuze ugweme i-weld "i-hot cracking" ngokuqinisekisa ukubunjwa kwe-ferrite kwi-weld deposit. Le ngxubevange ithathwa ngokubanzi ukuba inokutheleleka okuthelekisekayo kwiiNdidi 304 kunye ne-304L. Umahluko omkhulu ukongeza kwe-titanium okunciphisa okanye ukuthintela imvula ye-carbide ngexesha le-welding. Xa i-weld filler ifuneka, mhlawumbi i-AWS E/ER 347 okanye i-E/ER 321 isoloko ichazwa.Uhlobo lwama-321 lwaziwa kakhulu kuncwadi lwereferensi kwaye ulwazi oluthe kratya lunokufumaneka ngale ndlela.
