440 maitai - he kowiri tira. Steel 440: āhuatanga

ka karanga a Steel he pūhui o rino , me te waro. e kore e momo o te rauemi i whakaritea i roto i te ōwehenga o ngā wāhanga taketake, me i te kaupapa o te poke me tāpiritanga horo'araa hua āhuatanga rerekē me ngā āhuatanga.

Ka taea te wehea ngā momo o maitai, rite ki te kaupapa here utu ki subgroups, cheap, rongonui, me te utu. Te reira i katoa tei runga i te whakaaro o nga uauatanga rauemi o tona production. Ano, i reira he kahore koranu pai, ahakoa kino ahurei, rite rauemi mātātoa Kei te matatini o ngā āhuatanga e whakatau etahi tikanga. Tüturu, e taea te kite i te reira, ki te whakaaro tatou, mo te tauira, 440 maitai.

wāhanga maitai

kia Kounga maitai e āhuatanga wā kotahi kakahu ātete, taikaha, elasticity, te kānapanapa, taikaha, te manawanui me te waikura kaha Sharpening. I roto i te mahi, tata katoa o enei āhuatanga e tika ke ki tetahi ki tetahi. Ko tētahi o nga āhuatanga matua o te koranu, he kawenga hoki te pakeke me te rigidity, he waro. Hoki pūhui ki te ihirangi tiketike o reira ngā hunga i roto i nei te kukū o te hoatu huānga matū he nui atu i te 0.5%. Kakahu rawa resistance me te keno iti hoki foaki waikura Konqueror maitai. Ki te te taumata ko te nui ake i te 13%, tenei hua he kowiri tira.

rahi witi, kaha, pakeke homai te koranu o te konupora. Kei te whakamahia te reira i roto i te taahiraa o te rikarika ki a okeoke. Tenei parahi patua pera-ka karanga.

Ki te hua i tenei rauemi kihai i pakarukaru me pakarukaru a ano e ātete ki te wera, he pūhui ko tapiritia molybdenum. I roto i tenei take, ka karanga te koranu ko rangi-tineia.

E tauturu te reira whakaiti i te mōrea o te waikura, me te homai i te pakeke o te nika. whakarato Āhuatanga Pourewa, silicon rauemi. Tungsten me vanadium koranu homai te kaha, me te mauroa.

Āhuatanga maitai māka 440

440 pā ana ki ngā rauemi he kowiri tira. Kei te whakamahia te reira i te nuinga mo te hanga o maripi, whare hanganga. Ko te āhuatanga o tenei koranu he ātete ki te waikura, me te kaha nui. i roto i tenei raupapa hoki ko te painga o te ātete ki āhuatanga taiao, te wai, ki te kai, waikawa ngoikore me kawakore.

Steel māka 440 ngā momo 440A, 440B, 440C, me 440A raupapa - atu ngawari me te 440C - uaua. Heoi, ko te drawback ko te fragility o 440C me te ātete āhua iti ki te waikura i roto i te pā ana ki 440A ko 440B. Huri i te reira i roto i e taea waikura puta i runga i te whakapā auroa ki te houku kaitaua pāpāho ranei. Ahakoa ngā āhuatanga atu, waikura ārai, homai tenei koranu e tika ana ki te mata oro maheni.

E kore e tūtohu ana ki te whakamahi i 440 maitai i te pāmahana ki runga ake i tona mahana i roto i haere, mai i roto i tenei take e ngaro nga āhuatanga pūkaha o te koranu.

Ko te hanganga matū o te parahi 440

Steel 440, nga āhuatanga o e he tika ti'aturi i runga i te hanganga matū, rite ki te raupapa, kei te āhuatanga i roto i roto i te ripanga i raro nei.

Ka rite ki whakaaturanga te tepu, te ihirangi waro i raro o 440A raupapa, te teitei - 440C, e ko, te waitohu hou kaha atu i te katoa, me te tuatahi ko te tino ātete ki te waikura. Ahakoa raupapa katoa o te waitohu kounga tika teitei, me te whakawhiti kawenga pai.

Ko te āhuatanga ōkiko me te maimoatanga waiariki o kowiri tira 440

Steel 440 tawhā āhuatanga tinana mo te raupapa A, B, me C kua te whai ake:

• rauemi kiato - 7650 kg / cu. m;
• uara tawhiti - 200 GPA;
• kawe ia ngāwhā - 242 W / m kbp;.
• kaha wera motuhake - 460 J / kg.kb;.
• hiko resistivity - 600.

Pakeke o te maitai 440 rerekē i roto i 56-58 wae.

Ko te toharite whakarea roha waiariki, whanganga nei i roto i te mm / m / tohu centigrade i 440A raupapa - 10.1; 440B - 10.3; 440C - 11.7.

Heat maimoatanga o tenei rauemi e tika ana i te whai i ēnei:

• kōpeke ana;
• tinei;
• hararei.

Kōpeke ana e wahi i te pāmahana o + 850-900 degrees, aru e te whakaiti tamau ki _600. Tautauā puta i tikanga rangi. Na - damped tukanga kōpeke ana i 735-785 nekehanga, me te meangiti i roto i te oumu.

kawea Tempering i roto i + 1010-1065 degrees. Tinei - te whakamahi i te hinu mahana rangi ranei.

haere Vacation i + 150-370 nekehanga, kia homai te rauemi ko te pakeke e tika ana. I roto i nga momo o rauemi pērā i maitai 440, nga āhuatanga o te mahi mīhini i roto i te 440C kōeke pai. Ko te nuinga te utu nui, me te pono tenei koranu. tautuhi te reira i te paerewa hua kounga.

Tono Steel 440

Kei te nuinga 440 he kowiri tira whakamahia mo te hanga o maripi. Hire koranu homai hoki hanga ngā hua e kua paiherea atu pūhui ranei.

E hua Sheets o ngā hua oti ki matotoru i 4 ki te 50 mm. e kore e 440 maitai rapua e atu whakawera me te maimoatanga wera i roto i tona fehokotaki'anga. koranu watea, me te pono mo te hanga o ahunga, mongamonga o whare okana.

440A o te waitohu hua maripi atu tuke, tae atu raro, hopu. Ko te matatahi o te raupapa 440C i ngā āhuatanga tuhi pai, me te puaretanga pai o Sharpening, na kei te whakamahia i tēnei parahi mo te hanga o taputapu tapahi whiriwhiri.

Me koe ki te matau, ka hoko i te maripi tapanga "440" e kua whakamahia koranu iti te utu - 440A. I roto i te take o pūhui atu te utu 440B me ngā kaiwhakanao 440C utu tonu whakarongo ki reira.

kē waitohu

He he maha o rama kē, e taea te whakakapi i tenei koranu. Hei tauira, he raupapa o 440A / B roaa atu āhuatanga e whakapai ake i te ātete te waikura. Steel 440F he pou tarāwaho teitei i te kaha rite. Iho ki a ratou ake āhuatanga mō te pakeke māka 420. 416 raupapa he pou tarāwaho nui engari tika raro.

Ki te hanga koe maripi i 440A waitohu me ona analogs, he tika hoki te whakamahi ia rā enei hua. Ahakoa, he mea utu ki te tango ki pūkete te kounga o te tinei. Well kï i roto i tenei tukanga u Kol. Ko te kamupene "Randall" te nuinga hua matatahi maitai 440B.
