Wanne abu ne mafi alhẽri ga SUP7, SUP9, 50CrVA, ko 51CrV4 a karfe farantin marẽmari.

Zaɓin mafi kyawun abu tsakanin SUP7, SUP9, 50CrVA, da 51CrV4 don maɓuɓɓugan ƙarfe na ƙarfe ya dogara da dalilai daban-daban kamar kayan aikin injiniya da ake buƙata, yanayin aiki, da la'akarin farashi.Ga kwatancen waɗannan kayan:

1.SUP7kuma SUP9:

Waɗannan su ne nau'ikan ƙarfe na carbon da aka saba amfani da su don aikace-aikacen bazara.SUP7da SUP9 suna ba da elasticity mai kyau, ƙarfi, da tauri, yana sa su dace da aikace-aikacen bazara na gabaɗaya.Su ne zaɓuɓɓuka masu tsada kuma suna da sauƙin samarwa.

Duk da haka, suna iya samun ƙananan juriya na gajiya idan aka kwatanta da gami da ƙarfe kamar50 CrVAko 51CrV4.

2.50 CrVA:

50CrVA ne wani gami spring karfe dauke da chromium da vanadium additives.It yayi mafi girma ƙarfi, taurin, da gajiya juriya idan aka kwatanta da carbon steels kamar SUP7 da SUP9.50CrVA ya dace da aikace-aikace bukatar mafi girma yi da karko a karkashin cyclic loading yanayi.

Ana iya fifita shi don aikace-aikacen aiki mai nauyi ko matsananciyar damuwa inda manyan kayan aikin injiniya ke da mahimmanci.

3.51CrV4:

51CrV4 wani ƙarfe ne na bakin karfe tare da chromium da abun ciki na vanadium.Yana ba da irin wannan kaddarorin zuwa 50CrVA amma yana iya samun ƙarfi da ƙarfi kaɗan kaɗan.

Yayin51CrV4na iya bayar da ingantaccen aiki, zai iya zuwa a farashi mafi girma idan aka kwatanta da ƙarfe na carbon kamar SUP7 da SUP9.

A taƙaice, idan farashi yana da mahimmanci kuma aikace-aikacen baya buƙatar matsanancin aiki, SUP7 ko SUP9 na iya zama zaɓi masu dacewa.Koyaya, don aikace-aikacen da ke buƙatar ƙarfin ƙarfi, juriya, da dorewa, gami da ƙarfe kamar 50CrVA ko51CrV4zai iya zama wanda aka fi so.A ƙarshe, zaɓin ya kamata ya dogara ne akan yin la'akari da ƙayyadaddun buƙatu da ƙuntatawa na aikace-aikacen.
