I. Intshayelelo Esemgangathweni – Ilitye Lembombo Yeetyhubhu Zentsimbi Ezimelana Nobushushu Bemizi-mveliso YaseJamani

I-DIN 17175ngumgangatho weshishini laseJamaniiityhubhu ezingenamthungo ezenziwe ngeentsimbi ezimelana nobushushu, enesihloko esithi iityhubhu ezingenamthungo zeentsimbi ezingatshiyo. Isebenza kwiityhubhu ezingenamthungo - kuquka iityhubhu zeentloko - ezisetyenziswa ekwakheni iibhoyila, iipayipi, izitya zoxinzelelo kunye nezixhobo zokulungisa ukuya kuthi ga600 °Ckunye noxinzelelo oluphezulu ngaxeshanye.

Ngokwenkcazo: “Iintsimbi ezineempawu ezilungileyo zoomatshini nokuba zixinezelekile ixesha elide kumaqondo obushushu aphezulu, ukuya kuthi ga kwi-600 °C, ziya kuthathwa njengezimelana nobushushu kumaqondo obushushu aphezulu.” Iityhubhu mazinikwe zilungiswe ngokufanelekileyo ngobushushu kulo lonke ubude bazo.

Lo mgangatho ugubungela uluhlu olupheleleyo lweAmanqanaba entsimbi ali-9, ukususela kwiiintsimbi ezimelana nobushushu bekhabhonikwayeiintsimbi ezinganyangekiyo kubushushu ezisebenzisa i-alloy ephantsi to iintsimbi ezimelana nobushushu be-martensiticNjengoko kusetyenziswe amashumi eminyaka emininzi kwimveliso yeebhoyila zaseJamani naseYurophu kunye neenqanawa zoxinzelelo, i-DIN 17175 isasoloko iyindlela ekhankanyiweyo kakhulu yeentsimbi zepayipi ezinobushushu obuphezulu kunye noxinzelelo oluphezulu.

Inqaku elibalulekileyo:I-DIN 17175 ithathelwe indawo kakhulu yimigangatho evisisanayo yaseYurophuEN 10216-2(Iityhubhu zentsimbi ezingenamthungo ngeenjongo zoxinzelelo – Iimeko zokuhanjiswa kobuchwephesha – Icandelo lesi-2: Iityhubhu zentsimbi ezingezizo ezomxube kunye neze-alloy ezineempawu zobushushu obuphezulu ezichaziweyo). Nangona kunjalo, amagama e-DIN 17175 grade asasetyenziswa kakhulu kwihlabathi liphela, kwaye izityalo ezininzi ezikhoyo, uyilo oludala kunye neenkcukacha zobugcisa ziyaqhubeka nokuwakhankanya.
