Intsimbi Engagqwaliyo engama-30Cr13 (3Cr13)

Inkcazo:

Yintsimbi engatyiwayo yohlobo lwe-martensite. Uhlobo oludala: 3Cr13, uhlobo olutsha: 30Cr13

(Ngokuhambelana nomgangatho we-ASTMA waseMelika: S42080, umgangatho we-DIN waseJamani: 1.4028, umgangatho we-EN waseYurophu: X30Cr13)

Umxholo wokwakheka kweekhemikhali:

C:0.26-0.35	Ukuba: ≤1.00	Mn: ≤1.00	S: ≤0.030
P: ≤0.040	I-Cr:12.00-14.00	(Kwi: ≤0.60)

Ulwakhiwo lweMetallographic: Ulwakhiwo luphawulwa yisakhiwo se-martensitic.

Iimpawu zentsimbi engagqwaliyo ezingama-30Cr13 (3Cr13)

1. Le ntsimbi isebenza kakuhle ekuchwethezeni. Emva konyango lobushushu (ukucima nokulungisa), inokumelana nokugqwala okuhle kakhulu, ukusebenza kokupholisha, amandla aphezulu kunye nokumelana nokuguguleka.

2. Emva kokucinywa nokufuthwa, izinto ezingama-30Cr13 ezinobunzima obungaphantsi kwe-HRC30 zinokucutshungulwa ngcono kwaye zinokufikelela ngokulula umgangatho womphezulu ongcono. Nangona umgangatho womphezulu weendawo ezifakwe kwi-machine xa ubunzima bungaphezulu kwe-HRC30 ulungile, izixhobo zidla ngokuguga. Ke ngoko, emva kokuba izinto zingene kumzi-mveliso, ziyacinywa kuqala kwaye zifuthwe zibe lukhuni lwe-HRC25~30, emva koko zinqunyulwe.

3. Le ntsimbi inobunzima obuphezulu kwaye inamandla aphezulu, ubunzima kunye nokuqina kunentsimbi eyi-12 Cr13(1Cr13/410) kunye ne-20Cr13(2Cr13) emva kokucinywa. Kodwa ukudityaniswa akukuhle njenge-12Cr13 kunye ne-20Cr13. Ixabiso layo liphantsi phakathi kweebhola zentsimbi engagqwaliyo, kwaye ifanelekile kwiindawo zokusebenza ezineemfuno ezifanayo zentsimbi engagqwaliyo.

Isikopu sesicelo sentsimbi engagqwaliyo engama-30Cr13 (3Cr13)

1. Ifanelekile ukuvelisa iiplastiki ezithwala umthwalo omkhulu, ukumelana nokuguguleka okuphezulu kwaye zichaphazeleka kwimidiya erhabaxa;

2. Isebenza kuzo zonke iintlobo zoomatshini abachanekileyo, iibheringi, ukuvuza kombane, izixhobo, izixhobo, iimitha, izithuthi zothutho, izixhobo zasekhaya, njl.njl.;

3. Isetyenziswa kakhulu ekwenzeni iindawo ezimelana nokugqwala kwe-atmospheric, steam, water kunye ne-oxidizing acid;

4. Isetyenziswa kakhulu kwiindawo ezinamandla aphezulu kunye neendawo ezigugileyo ezithwala imithwalo enzima kwaye zisebenza kwiindawo ezithile ezirhabaxa. Umzekelo, izixhobo zokusika kunye nezipringi ezisebenza ngaphantsi kwama-300℃, kunye neeshafts, iibholiti, iivalvu, iibheringi, njl.njl. ezisebenza ngaphantsi kwama-400℃ nazo zisetyenziswa njengezixhobo zokulinganisa kunye nezixhobo zonyango.

Inkampani iSanyao inokubonelela abathengi nge-forging eyenzelwe wena (kubandakanya ubungakanani, ubulukhuni, i-eye bolt, i-rough machining, i-quenching kunye ne-tempering, i-rough surface grinding, i-fine surface grinding, njl.njl.) ukuhlangabezana neemfuno zabathengi ngabanye.
