Dulmar guud ee dhuumaha birta daawaha
Dhuumaha birta Alloy waxaa loo isticmaalaa codsiyada u baahan guryaha iska caabbinta daxalka dhexdhexaad ah oo leh adkeysi wanaagsan iyo kharash dhaqaale. Si fudud loo dhigo, tuubooyinka daawaha ayaa la door bidaa meelaha tuubooyinka birta ee kaarboonku ay fashilmi karaan. Waxaa jira laba nooc oo birta daawaha ah - Alloys sare iyo birta daawaha hoose. Tubooyinka ka kooban birta daawaha hoose waxay leeyihiin maaddooyin alloying oo u dhexeeya 5%. Halka maadada daawaynta ee birta daawaha sare u dhaxayso 5% ilaa 50%. Si la mid ah inta badan Alloys-ka awoodda cadaadiska shaqada ee Alloy Steel Tubta aan Xumaan lahayn waxay ku saabsan tahay 20% ka sarreeya tuubada alxanka. Sidaa darteed codsiyada leh cadaadis shaqo oo sarreeya sida shardi ahaan, isticmaalka tuubo aan fiicneyn ayaa xaq ah. In kasta oo uu ka xoog badan yahay tuubada alxanka, haddana qiimuhu aad buu u sarreeyaa. Intaa waxaa dheer, khatarta daxalka intergranular ee aagga alxanka ee kuleylku saameeyay waxay ku badan tahay alaabta alxanka ah. Farqiga muuqda ee u dhexeeya birta alxanka leh ee Alloy Steel iyo badeecada aan kala go 'lahayn waa tolitaanka latitude ee dhererka tuubada. Si kastaba ha ahaatee, maanta, iyada oo horumarka tignoolajiyada, tollaynta ku jirta Dhuumaha Alloy Steel ERW si weyn ayaa loo dhimi karaa iyada oo la adeegsanayo daawaynta dusha sare, sida in ay ahaato mid aan la arki karin indhaha bini'aadamka.
