Halayen Gwanin Karfe Mai Saurin Karfe
1. Haskewar juriya: kayan ƙarfe na bakin ciki suna nuna kyawawan juriya na Fruressa, suna ba da izinin yankan gefuna don su kasance da kaifi don tsawan lokaci.
2. Ƙarfin Ƙarfafa Ƙarfi: Ƙarfe mai sauri zai iya aiki a cikin yanayin zafi mai zafi ba tare da hasara mai mahimmanci ba ko lalacewa.
3. Excellent Yankan Performance: Karkace tsagi zane na karkatarwa drills na taimaka wa tasiri karfe yankan yayin da rage guntu tara.
4. Amintaccen Machining Quality: High-gudun karfe karkatarwa drills yawanci isar da high quality-dire hazo ramukan da madaidaicin girma da kuma santsi saman.
Nau'ikan HSS da Muka Yi Amfani da su Don Matsalolin mu na Twist
Babban maki na HSS da muke amfani da su sune: M42, M35, M2, 4341, 4241.
Akwai wasu bambance-bambance a tsakanin su, galibi suna da alaƙa da sinadarainsu, taurinsu, kwanciyar hankali na zafi da wuraren aikace-aikace.A ƙasa akwai babban bambance-bambance tsakanin waɗannan maki na HSS:
1. M42 HSS:
M42 ya ƙunshi 7% -8% cobalt (Co), 8% molybdenum (Mo) da sauran gami.Wannan yana ba shi mafi kyawun juriya na abrasion da kwanciyar hankali na thermal.M42 yawanci yana da taurin mafi girma, kuma taurinsa na rockwell shine 67.5-70(HRC) wanda za'a iya samu ta hanyar dabarun maganin zafi.
2. M35 HSS:
M35 ya ƙunshi 4.5% -5% cobalt kuma yana da juriya mai girma da kwanciyar hankali na thermal.M35 ya ɗan fi ƙarfin HSS na al'ada kuma yawanci yana kiyaye taurin betweeb 64.5 da 67.59(HRC).M35 ya dace da yankan m kayan kamar bakin karfe.
3. M2 HSS:
M2 ya ƙunshi manyan matakan tungsten (W) da molybdenum (Mo) kuma yana da kyawawan kaddarorin yanke.Taurin M2 yawanci yana cikin kewayon 63.5-67 (HRC), kuma ya dace da mashin ɗin ƙarfe waɗanda ke buƙatar buƙatu mafi girma.
4. 4341 HSS:
4341 HSS babban karfe ne mai sauri tare da ƙaramin abun ciki na gami da ɗan ƙaramin ƙarami dangane da m2.Ana kiyaye taurin gaba ɗaya sama da 63 HRC kuma ya dace da ayyukan aikin ƙarfe gabaɗaya.
5. 4241 HSS:
4241 HSS kuma ƙaramin alloy HSS ne wanda ke ɗauke da ƙananan abubuwan haɗaka.Ana kiyaye taurin gaba ɗaya a kusa da 59-63 HRC kuma yawanci ana amfani dashi don aikin ƙarfe na gabaɗaya da hakowa.
Zaɓin matakin da ya dace na HSS ya dogara da takamaiman buƙatun aikace-aikacenku da nau'in kayan da za'a sarrafa.Tauri, juriya na abrasion da kwanciyar hankali na thermal sune mahimman abubuwan da ke cikin zaɓin.
