Ngati malo anu opangira zinthu nthawi zambiri amakonza makontrakitala ochokera ku Asia, ndiye kuti mumadziwa za Japanese Industrial Standards (JIS) za zitsulo zazitsulo. Zojambula zaumisiri nthawi zambiri zimafotokoza zinthu zomwe zimagwiritsidwa ntchitoSKkapenaSKSma prefixes.
Kwa oyang'anira zogula zinthu padziko lonse lapansi, kupeza zitsulo zenizeni zaku Japan kumatha kukhudza kwambiri phindu. Mfungulo yosunga bwino pamene mukuchepetsa mtengo ndikumvetsetsa zitsulo zomwe zili kumbuyo kwa ma JIS ndi kudutsa-kuwalozera ndi miyezo yapadziko lonse lapansi (monga AISI kapena Chinese GB).
Bukuli limathetsa kusiyana kwa mankhwala ndi thupiMaphunziro a Zitsulo za SK ToolndiMaphunziro a SKS Steel, kupereka mwachindunjizofanana ndi zogula zanu zopangira.
Kodi SK Tool Steel Grades ndi chiyani? (Chitsulo cha Carbon Tool)
Chithunzi cha "SK".kusaina kumayimiraChitsulo Kougu(Kougu amatanthauza "chida" mu Japanese). Izi ndi zomvekazida za carbon zitsulo. Iwo ali mkulu misinkhukaboni (nthawi zambiri 0.60% mpaka 1.30%) popanda zinthu zina zowonjezera.
Makhalidwe a Zitsulo za SK:
- Kuwumitsa: THei ndi zitsulo zamadzi-zowumitsa.
- Kachitidwe:Amakhala ndi kuuma kwapamwamba kwambiri komanso kusunga chakuthwa m'mphepete koma amakhala ndi kutentha kochepa.
- Mapulogalamu:Amagwiritsidwa ntchito makamaka popondaponda mozizira, zida zamanja, nkhwangwa, ndi masamba odulira pomwe kutentha kumakhalabe pansi.200 digiri.
Magulu Odziwika a SK ndi Zofanana Padziko Lonse:
- JIS SK2 (SK120):Muli pafupifupi 1.20% Carbon. Amapereka kuuma kwakukulu ndi kukana kuvala koma kutsika kolimba.
Zofanana Padziko Lonse:AISI W1 (High Carbon),GB T12.
- JIS SK4 (SK85):Muli pafupifupi 0.85% Carbon.Mtengo wa SK4ndiye chitsulo chomwe chimagwiritsidwa ntchito kwambiri-chomwe chimagwiritsidwa ntchito kwambiri, chopatsa mphamvu zambirikuuma ndi kulimba.
Zofanana Padziko Lonse:AISI W108,GB T8/T10.

Kodi SKS Tool Steel Grades ndi chiyani? (Chitsulo cha Aloyi)
Chithunzi cha "SKS".kusaina kumayimiraZitsulo Kougu Special. Izi ndizida za aloyi. Kuti muthane ndi zovuta zosweka ndi kupotoza zomwe zimadziwika bwinoZitsulo za SK, metallurgists amawonjezera zinthu zina monga chromium (Cr), tungsten (W), ndi silicon (Si).
Makhalidwe a Zitsulo za SKS:
- Kuwumitsa: Most SKS magiredi ndi mafuta-oumitsa, omwe amachepetsa kwambiri kupindika ndi kupotoza panthawi yochiritsa kutentha.
- Kachitidwe:Amapereka kukhazikika kwapamwamba kwambiri, kulimba kwakuya, komanso kukana kugwedezeka kwambiri poyerekeza ndi ma SK.
- Mapulogalamu:Zomwe zimagwiritsidwa ntchito pozizira kwambiri zimafa, zida zoyezera molondola, ndi zida zodulira modzidzimutsa-zokana.
Magulu Odziwika a SKS ndi Zofanana Padziko Lonse:
- JIS SKS3: Chitsulo chosasunthika kwambiri-chitsulo chowumitsa chomwe chimagwiritsidwa ntchito poyesa kufa ndi geji.
Zofanana Padziko Lonse:AISI O1,GB 9CrWMn / Cr2.
- JIS SKS7 / SKS41:Aloyed kuti pazipita mayamwidwe.
Zofanana Padziko Lonse:Zitsulo Zolimbana ndi Shock,GB 9SiCr.

SK vs SKS: Ndi Zinthu Ziti Zomwe Chojambula Chanu Chimafunikira?
Mukamalankhulapotengera zojambula za JIS pogula zinthu zakomweko, gwiritsani ntchito izi mwachangu:
| Mbali | Maphunziro a SK (Carbon) |

| Material Base | Plain High Carbon |
Carbon + Cr, W, Si |
| Njira yochotsera | Madzi (Kuopsa kwakukulu kosokoneza) |
Mafuta (okhazikika) |
| Ubwino Woyambirira | Zotsika mtengo, zakuthwa kwambiri koyamba |
Kulimba, kupotoza kochepa |
| Zabwino Kwambiri | Kufa kosavuta, matabwa, zida zamanja |

Kupeza Mtengo-Zofanana Zogwira Ntchito ndi Promisteel
Simumateroayenera kuitanitsa zipangizo kuchokera ku Japan kuti akwaniritse zofunikira za JIS engineering. China imapanga makemikolo ofanana ndendende ndi magiredi onse a SK ndi SKS, otsimikiziridwa ndi Sitifiketi Zoyeserera za Mill Mill (MTC).
Potchula zofanana zamtundu wa China GB (monga T10 ya SK4, kapena 9SiCr ya magiredi a SKS), opanga amatha kuchepetsa mtengo wazinthu zopangira mpaka 30% popanda kugwiritsa ntchito zida.
