CrWMn mate paraharaha maitai he koranu taputapu maitai, hinu tinei iti deformation matao mahi mate steel.The wearability maitai, e tika ana ki te uru te hautanga papatipu o 1.20% ~ 1.60% o tungsten, hanga carbide na i muri tinei me te iti pāmahana ki te whai ⼀ pakeke me Abrasion resistance.Tungsten help to keep fine grains from the steel more pliable.The steel is sensible to forming carbon, which may cause the bladder to spalling.Ahakoa te kaha, te pakeke me te pakari o te maitai he teitei ake i to te waro maitai, he koha tona penei i te ngatata me te huri oro na te wehenga o te carbide. Ko te tinei ka pa ki te waro maitai, a ka heke te awhe tono. Ko te pakari me te atete abrasion o te maitai tae atu ki te pakeke o te chromium maitai me te chromium silicon maitai i muri he pai te tinei, he pai hoki te pakari.
Ko te CrWMn te nuinga e whakamahia ana mo te waro taputapu maitai e kore e taea te whakatutuki i nga whakaritenga o te waahanga whiti nui, he ahua uaua ake o nga waahanga mate, me iti ake te tiini deformation
1) Kei te whakamahia nuitia tenei momo maitai i roto i te tukatuka maitai angiangi, whakarewa kore-ferrous, rauemi taketake o te kawenga marama, me te ahua matatini matao takatakahia mate, rawa i roto i te mara o te karaka, taputapu, ha'uti me te ahumahi hua, me ētahi atu Te pānga o Ko te pereti maitai austenite, te pereti maitai silicon me te pereti maitai kaha teitei kaore i te pai.
2) ka taea te whakamahi i te matotoru o te maitai ki te hanga rauemi < 1 mm o te kowhatu mate whakaraerae, te mate concave, te huinga huinga, me nga whenu ⼀ o te mate tuhi hohonu. Ko te whakaputanga punch i kii mai i te 58 ki te 62 HRC te pakeke, a ko te hanga o te pokepokea concave i kii ko te pakeke 60 ~ 64 HRC.
3) Ka whakamahia mo te whakaurunga o te punch die me te kaha o te mau kakahu me te ahua uaua ki te piko o te mate. Ko te pakeke o te mate punch e taunaki ana kia 58 ~ 62HRC me te 60-64hrc ka tūtohu kia 60-64hrc ka mate te whiu.
4) He mate convex me te concave mate mo te whakamatao makariri mate o nga wahi konumohe.Ko te pakeke o te 60 ~ 62HRC e taunakihia ana mo te mate punch me te 62 ~ 64HRC e taunakihia ana mo te mate punch.
5) Mo te whakakorenga matao ka mate o nga waahanga parahi me te whakakorenga makariri ka mate me te mate o nga waahanga rino, ko te pakeke e taunakihia ana ko 62-64hrc.
6) I muri i te hangahanga, ka taea te whakamahi ki te hanga i nga miihini whakakikorua nui e whakamahia ana i runga i nga miihini pehanga neke atu i te 1mm, ka piki ake te pakeke o te maitai ki te 50-55hrc. Heoi ano, me whakaheke, ka karohia ranei nga ngoikoretanga o te kiko penei i te hanganga carbide carbide me te chromatography wai.
