Eseese tempering vevela o le a maua ese maaa. Tempering masani o le 204 ° C, ina ua uma ona tempering faigata 61HRc Min.

Uilaina o mea uamea Cr12

I se tulaga lautele, matou te le fautuaina le welGBg o le uʻamea meafaigaluega uʻamea ae o nisi taimi e manaʻo ai tagata e faʻaogaina ina ia aloese mai le tau o le toe faʻaleleia. E tatau ona manatua o lenei vasega o se uʻamea faʻamaʻa ea ma o le welGBg o le vaega o le uelo e maua ai le vevela e tusa ma le 1000 ° C. E ono tupu le ta'e i le taimi e mālūlū ai se'i vagana ua faia ni puipuiga lelei. O auala lauiloa o le welGBg o le hydrogen atomic ma le argon arc. Matou te fautua atu e te fa'afeso'ota'i lau kamupani fa'atau oloa fa'aaogā welGBg e tatau ona tu'uina atu ia te oe fesoasoani atoatoa ma fa'amatalaga i u'amea u'amea u'amea welGBg.

Nitriding o mea uamea Cr12

Cr12 u'amea meafaigaluega u'amea e mafai ona nitrided e maua ai se tulaga malo malo. A maeʻa le faʻamaʻiina o le vevela o le nitriGBg, o le Cr12 e matua teteʻe i le ofuina ma le tafia. NitriGBg faʻateleina foʻi le teteʻe i le pala.

Fa'ai'u ole olo ole mea uamea Cr12

GringGBg le GB Cr12 Steel. Filifili le vasega sa'o ole uili ile feutagai ma le gringGBg fai uili. Ia mautinoa o lo'o lelei le uili gringGBg e ala i se meafaigaluega fa'aofuina talafeagai. O le gringGBg susu o se filifiliga e sili ona lelei e fa'aaoga ai le tele o sapalai o le fa'amalulu. Afai e fai le gringGBg mago ona fa'aoga lea o se uili vaivai.
