Waxaa hubaal ah in ay jiri doonto khasaare xagga isticmaalka birta toogashada ah iyo birta, waxaana jiri doona khasaare kala duwan sababtoo ah habka loo isticmaalo iyo walxaha kala duwan ee isticmaalka. Markaa ma ogtahay in nolosha adeegga ee tallaalada birta ee adag ee kala duwan ay sidoo kale ka duwan tahay?
Guud ahaan, adkaanta toogashada birta waxay u dhigantaa xawaaraha nadiifinta, taas oo ah, kor u kaca adayga birta, si dhakhso ah xawaaraheeda nadiifinta, taas oo sidoo kale ka dhigan in isticmaalka tallaalka birta uu noqon doono mid weyn iyo nolosha adeegga. ayaa ka gaaban doona.
Tallaalka birta ahi waxa ay leedahay saddex adag oo kala duwan: P (45-51HRC), H (60-68HRC), L (50-55HRC). Waxaan tusaale ahaan u soo qaadannaa P hardness iyo H engegnaanta isbarbardhigga:
Adaggu guud ahaan waa HRC45 ~ 51, farsamaynta qaar ka mid ah biraha adag, waxay kordhin kartaa adayga ilaa HRC57 ~ 62. Waxay leeyihiin adayg wanaagsan, adeeg nolol dheer marka loo eego H engegnaanta, iyo codsiyo kala duwan.
H engegnaanta waa HRC60-68, noocan oo kale ah birta toogashada adag tahay, qaboojiyaha waa mid aad u jajaban, aad u fudud in la jebiyo, nolosha gaaban, codsiga ma aha mid aad u ballaaran. Inta badan waxaa loo isticmaalaa meelaha u baahan xoojinta ilbaxnimada toogashada sare.
Sidaa darteed, macaamiisha intooda badani waxay iibsadaan tallaalada birta leh P adag.
Sida laga soo xigtay tijaabada, waxaan ogaanay in tirada wareegyada birta toogashada leh P adag ay ka sarreeyaan ta H adag, H engegnaanta waa qiyaastii 2300 jeer, iyo P engegnaanta wareegga waxay gaari kartaa 2600 jeer. Immisa wareeg ayaa tijaabisay?
