Intsimbi engenastainless 304,304L,304H

Insimbi engenasici i-304 kunye ne-stainless steel 304L zikwabizwa ngokuba yi-1.4301 kunye ne-1.4307 ngokulandelanayo. I-304 yeyona ntsimbi isetyenziswa kakhulu kwaye isetyenziswa ngokubanzi. Ngamanye amaxesha kusabhekiswa kuyo ngegama layo elidala elithi 18/8 elithatyathwe kulwakhiwo oluqhelekileyo lwe-304 ibe yi-18% yechromium kunye ne-8% yenikeli. I-304 yensimbi engenasici linqanaba le-austenitic elinokutsalwa ngokunzulu kakhulu. Lo mhlaba ukhokelele ekubeni i-304 ibe lelona bakala lisetyenziswa kakhulu kwizicelo ezifana neesinki neepani.

I-304L yinguqulelo yekhabhoni ephantsi ye-304. Isetyenziswa kwigeyiji enzima kwizinto eziphuculweyo zokuweldability.

I-304H, i-carbon content variant, iyafumaneka ukuze isetyenziswe kumaqondo aphezulu.

Olu luthelekiso luqikelelo kuphela. Uluhlu lwenzelwe uthelekiso lwezixhobo zokusebenza ezifanayo hayi njengeshedyuli yeekhontrakthi ezilinganayo. Ukuba ukulingana ngqo kuyafuneka, kufuneka kuqwalaselwe iinkcukacha zokuqala.

AmaBanga anokuthi abekhona

IBanga	Kutheni inokuthi ikhethwe endaweni ye-304
301L	Umgangatho ophezulu wokuqiniswa komsebenzi uyafuneka kuluhlu oluthile oluqulunqiweyo okanye ulwakhiwo oluthile.
302HQ	Iqondo eliphantsi lokuqina lomsebenzi liyafuneka ukuze kufakwe izikrufu ezibandayo, iibholithi kunye neerivethi.
303	I-machinability ephezulu efunekayo, kunye nokuxhathisa okuphantsi kwe-corrosion, ukwakheka kunye ne-weldability yamkelekile.
316	Ukuxhathisa okuphezulu kwi-pitting kunye ne-crevice corrosion iyafuneka, kwiindawo ze-chloride
321	Ukumelana ngcono kumaqondo obushushu amalunga ne-600-900 °C iyafuneka...321 inamandla aphezulu ashushu.
3CR12	Ixabiso eliphantsi liyafuneka, kwaye ukuxhathisa okucuthiweyo kokutya kunye nesiphumo sokutshintsha kombala kwamkelekile.
430	Ixabiso eliphantsi liyafuneka, kwaye ukuxhathisa okuncitshisiweyo kwe-corrosion kunye neempawu zokwenza izinto zamkelekile.
