Babu makawa za a yi asara a amfani da ƙarfe da ƙarfe, kuma za a yi asara daban-daban saboda yadda ake amfani da shi da kuma abubuwan da ake amfani da su daban-daban. Shin kun san cewa tsawon lokacin aikin ƙarfe mai tauri daban-daban shi ma ya bambanta?
Gabaɗaya, taurin harbin ƙarfe yana daidai da saurin tsaftacewarsa, wato, mafi girman taurin harbin ƙarfe, saurin tsaftacewarsa yana da sauri, wanda hakan ke nufin cewa yawan amfani da harbin ƙarfe zai fi girma kuma tsawon sabis ɗin zai yi gajere.
Harbin ƙarfe yana da tauri daban-daban guda uku: P (45-51HRC), H (60-68HRC), L (50-55HRC). Mun ɗauki tauri na P da tauri na H a matsayin misalai don kwatantawa:
Taurin P gabaɗaya HRC45 ~ 51 ne, yana sarrafa wasu ƙarfe masu tauri, yana iya ƙara taurin zuwa HRC57 ~ 62. Suna da tauri mai kyau, tsawon rai fiye da taurin H, da kuma aikace-aikace iri-iri.
Taurin H shine HRC60-68, irin wannan taurin ƙarfe yana da yawa, sanyaya yana da rauni sosai, yana da sauƙin karyewa, yana da ɗan gajeren lokaci, amfani ba shi da faɗi sosai. Ana amfani da shi galibi a wuraren da ke buƙatar ƙarfin fitar da harbe-harbe mai yawa.
Saboda haka, yawancin abokan ciniki suna siyan bindigogin ƙarfe masu tauri na P.
A bisa ga gwajin, mun gano cewa adadin zagayowar ƙarfe da aka harba tare da taurin P ya fi na taurin H girma, taurin H ya kai kusan sau 2300, kuma zagayowar taurin P zai iya kaiwa sau 2600. Darussan nawa kuka gwada?
