EN10216-5 Amashubhu weNsimbi angathungi weenhloso zokugandeleleka emazingeni womtjhiso aphakemeko - Izimo zokulethwa kwezobuchwepheshe
Ilwazi loku-oda
Abathengi kufanele bacacise:
- Ubunengi (ubude, inani lamashubhu)
- Ubukhulu (ububanzi bangaphandle, ukujiya kweboda)
- Ibanga lensimbi (isib., 1.4301, 1.4404)
- Isimo sokulethwa (isib., isisombululo esivuthiweko)
- Iimfuneko zokuhlola (isib., ukuhlolwa okungabhubhisi, umfutho we-hydrostatic)
- Nanyana ngiziphi iimfuneko ezikhethekileko (isib., ukuhlanzeka okukhethekileko kokusetjenziswa kwenyukliya).
Amazinga wensimbi nokwakheka kwamakhemikhali
Izinga lifaka hlangana i-austenitic stainless steels, kufaka hlangana:
- Amabanga ajwayelekileko: 1.4301 (304), 1.4404 (316L), 1.4541 (321), 1.4571 (316Ti), njll.
- Amazinga womtjhiso aphezulu: 1.4919, 1.4958, njll.
- Imikhawulo yokwakheka kwe-C, Si, Mn, P, S, Cr, Ni, Mo, N, njll., icaciswe.
Ubujamo bokukhiqiza nokuletha
- Indlela yokukhiqiza: Engenamthungo, eqediwe emakhazeni/etjhisako.
- Ukuphathwa ngokutjhisa: Ukutjhisa ngesisombululo (okuqakathekileko eensimbini ze-austenitic).
- Ukuqedwa kwendawo: Ayikho isikali, imifantu, namaphutha; kungatlhogeka bona kubekwe i-pickling nofana i-passivation.
Iimfuneko zokuhlola nokuhlola
1 Izakhiwo zemitjhini
- Ukuhlolwa kokuqina (Rm, Rp0.2, ukunwebeka)
- Ukuhlolwa kobudisi (nangabe kuyatlhogeka)
2 Ukuhlolwa okungabhubhisi (NDT)
- Ukuhlolwa kwe-Eddy current nofana kwe-ultrasonic ukuthola ukubogaboga.
- Ukuhlolwa kwe-hydrostatic (ngokuzikhethela, ngaphandle kobana kuvezwe).
3 Ezinye iinhlahlubo
- Ukuhlolwa kobukhulu beenthoro (kwamagreyidi athileko)
- Ukuhlolwa kokugqwala kwama-intergranular (isib., ukuhlolwa kwe-Strauss kokuzwela).
Ukutshwaya nokuqinisekiswa
- Amashubhu kufanele atshwayelwe:
- Ibizo/ilogo yomkhiqizi
- Igreyidi yensimbi
- Ubukhulu
- Inombolo yokutjhisa
- Ireferensi ejwayelekileko (EN 10216-5).
- Isitifiketi sokuhlola 3.1 nofana 3.2 (EN 10204).
Ukubekezelelana nobukhulu
- Ihlanganisa ukubekezelela ububanzi bangaphandle, ukujiya kweboda, ukuqondisa, nobude.
