Simbi dzinowanzo shandiswa dzinoti 304 ne316, dzine extensions dzinosanganisira 304L, 316L, uye 316H. Pamusoro pezvo, kune 440C, 2507, nezvimwewo. Saka chii chinonzi CF8M neCF3? Ndingakwanisa sei kuramba ndichiona F316? Chii chiri kuitika neTP316L?
1. Kuti tijekese izvi, ngatitangei tatarisa chimiro chezvinhu. Muindasitiri yemavharuvhu nemidziyo yekuisa zvinhu, zvinhu zvinoshandiswa zvinonyanya kushandiswa kugadzira zvinhu, kugadzira zvinhu zvemabhawa, kugadzira zvinhu, nemapombi. Ndezvipi zvinodiwa zvinoenderana nemhando idzi ina dzezvinhu muindasitiri yedu? Ndapota tarisai tafura iyi:
|
| 304 | 304L | 316 | 316L |
| Kugadzira | F304 | F304L | F316 | F316L |
| Zvitoro zvebhawa | 304 | 304L | 316 | 316L |
| Kukanda | CF8 | CF3 | CF8M | CF3M |
| Pombi | TP304 | TP304L | TP316 | TP316L |
Zvinhu zvebhawa zvinoshandisa giredhi rekutanga, uye F inowedzerwa paforingi, uko F inomiririra forging; C yakawedzerwa paforingi, uko C inomiririra casting; TP yakawedzerwa paporingi, zvinoreva poringi.
2、 Ndeupi musiyano uripo pakati pe304 ne316? Chii chinonzi L ye304L ne316L? Chii chinonzi H ye316H? Ngatitarisei tafura yekuumbwa kwemakemikari emagiredhi akasiyana eASTM A276, apo 316H ndiyo ASTM A182 standard (giredhi iri harisi mu276 standard):
| Giredhi | Kuumbwa kwemakemikari,% | ||||||||
|
| C | Mn | P | S | Si | Cr | Ni | Mo | Zvimwe |
| 304 | 0.08 | 2.00 | 0.045 | 0.030 | 1.00 | 18.0-20.0 | 8.0-11.0 | … | … |

| 316 | 0.08 | 2.00 | 0.045 | 0.030 | 1.00 | 18.0-20.0 | 10.0-14.0 | 2.00-3.00 | … |
| 316L | 0.030 | 2.00 | 0.045 | 0.030 | 1.00 | 18.0-20.0 | 10.0-14.0 | 2.00-3.00 | … |
| 316H | 0.04-0.10 | 2.00 | 0.045 | 0.030 | 1.00 | 16.0-18.0 | 10.0-14.0 | 2.00-3.00 | … |
Sekureva kwetafura, zviri pachena kuti L zvinoreva kabhoni shoma, H zvinoreva kabhoni yakawanda, uye musiyano uripo pakati pe316 ne304 ndewekuwedzerwa kweMo element, zvinoreva kuti CF3M ine Mo element yakawedzerwa zvichienzaniswa neCF3.
3、 Kunze kwesimbi idzi dzinogara dzichishandiswa muzvikamu zvitatu, chii chimwe chinonzi 2507, 440C nedzimwe? Idzi simbi dzinogara dzichishandiswa muzvikamu zvitatu dzinonzi austenitic stainless steels, nepo 2507 iri duplex steel (ferritic uye austenitic), 440C ndeye martensitic stainless steel, uye kunewo ferritic stainless steels dzakadai se430.
Zvinogona kuonekwa kuti kuti tijekese simbi idzi dzinoshandiswa nevanhu, chekutanga ndechekusiyanisa chimiro chadzo: mapaipi ebhawa, nezvimwewo, chechipiri mitemo inoteverwa, uye chechitatu musiyano wekugadzirwa kwadzo. Kubva pamaonero aya, mushure mekuzviziva zvinoreva makodhi emavara, hazvina kuoma kunzwisisa zvinorehwa nemagiredhi aya.
Hikelok, nyanzvi yekugadziramavharuvhu ezvishandiso uye zvigadziko.
Kuti uwane rumwe ruzivo rwekuodha, ndapota tarisa sarudzo yachomakatarogupaWebhusaiti yepamutemo yaHikelokKana muine mibvunzo yekusarudza, ndapota taurai nevashandi vekutengesa veHikelok vanoshanda maawa makumi maviri nemana online.
