Kumashishini apho iinxalenye zentsimbi zinyamezela ukungqubana, impembelelo, kunye nokuqhawuka mihla le,nxiba ukumelanaiba yipropati ebalulekileyo. Nokuba ziigiya ezijikelezayo phantsi komthwalo onzima okanye ishafti ezinyamezela ukushukuma okuphindaphindiweyo, amacandelo kufuneka enziwe ngemathiriyeli eyomelele ngokwaneleyo ukuba ihlale. Enye yeentsimbi ezithembekileyo kulo mmandla4140 intsimbi yentsimbi.
Eyaziwayo ngamandla ayo omatshini kunye nokuqina kwayo, i-4140 iphinda ibonise ukuxhathisa okuchukumisayo-xa iqhutywe ngokuchanekileyo.sakysteeliphonononga ukuba iqine kangakanani na i-4140 yentsimbi xa isiza ekuxhathiseni ukunxitywa, kwaye kutheni iyimathiriyeli efanelekileyo yoxinzelelo oluphezulu, izicelo zokunxiba okuphezulu.
Yintoni i-4140 Steel?
4140 nguintsimbi ye-chromium-molybdenum ephantsienika indibaniselwano eyodwa yamandla, ukuqina, ukuqina, kunye nokumelana nokunxiba. Yinkqubo yokuhlelwa kwentsimbi ye-AISI-SAE kwaye isetyenziswa ngokuqhelekileyo ekwenzeni amacandelo achanekileyo, oomatshini abanzima, kunye nezixhobo zokusebenza.
Ukwakheka kweekhemikhali okuqhelekileyo:
-
Ikhabhoni: 0.38 - 0.43%
-
I-Chromium: 0.80 - 1.10%
-
IManganese: 0.75 - 1.00%
-
