430 Stainless Steel

General Properties

Grade 430 iri ferritic, yakananga chromium, non-hardenable mamakisi ari, tichibatanidza zvakanaka ngura nemishonga uye formability unhu pamwe anobatsira zvemaziso ehupfumi. Kukwanisa kwaro kurwisa nitric iine acid kurwisa achibvumira kushandiswa kwayo chaiyo namakemikari zvikumbiro asi motokari Trim uye mudziyo zvinoriumba inomirira minda yayo pakukura chikumbiro.

Grade 430F ndiye akasununguka-machine shanduro mamakisi ichi, rinowanikwa bhaa muchimiro dzokushandisa zvaitika sikuruwa michina. Grade 434 ndiyo molybdenum zvinobereka shanduro Grade 430 uye ane chete anobatsira mubatanidzwa zvivako. Its molybdenum Kuwedzera kunonatsiridza ngura nemishonga.

ehupfumi izvi nokuti 430 vari kutaurwa kuti sandara anokungurutsirwa chigadzirwa (ndiro, jira coils) muna ASTM A240 / A240M. Zvakafanana asi kwete kufanana ehupfumi vari wainyatsotaura kuti zvimwe zvigadzirwa akadai forgings nomuzariro mu dzawo nokurondedzerwa. Properties pamusoro Grade 430F vari wainyatsotaura kuti bhaa muna ASTM A582.

ngura Nemishonga

Grade 430 rine nemishonga zvakanaka zvakasiyana-siyana kungatikanganisa enviornments, kusanganisira nitric asidhi uye vamwe Organic acids. It Chinobudirira kwayo kunonyanyisa ngura kuramba kana ari zvikuru yakabwinyiswa kana buffed ezvinhu. Vakawanda kudzivisa rayo pitting uye crevice ngura kuramba ari pedyo kuti mamakisi 304. Stress ngura cracking walnut nemishonga kuti Grade 430 chaizvo, sezvazvakaita vose ferritic mamakisi.

Kufanana nevamwe mukuru-sarufa akasununguka machine mamakisi 430F akaita akaderedza kuramba pitting uye crevice ngura zvichienzaniswa yaro non-isina machine nerokuti zvikuru.

Heat Nemishonga

Grade 430 ungapikisa oxidation mu inoratidza basa kusvikira 870 ° C uye kusvika 815 ° C muna kuramba basa. mamakisi Izvi zvinogona kuva pfava pa nzvimbo tembiricha pashure kwenguva refu kudziyisa muna 400-600 ° C siyana. Izvi zvinogona kubviswa nokuda annealing.

Heat Treatment

1.Solution Annealing - Heat kuti 815-845 ° C, bata kuti ½ awa chete 25mm pamusoro ukobvu, anononoka choto inotonhorera 600 ° C uye ipapo nokukurumidza mhepo inotonhora. Slow kutonhora kubva 540-400 ° C achaita embrittlement.
2.Sub-Critical anneal - Heat kuti 760-815 ° C uye mhepo inotonhora kana mvura angazvidzimura.
3.This mugwaro hakusi hardenable nokuda chafariz kurapwa.
4.Pre-kupisa pa 150-200 ° C kana nomoto kunokosha.
5.Embrittlement ari weld simbi uye kupisa sei mapazi kunogona kupedzwa noruoko post-weld anneal pa 790-815 ° C
6.Grain chakagadziridzwa hazvizoitiki.
7.Easier kuti muchina kupfuura mwero austenitic mamakisi akadai 304.
8.Still katsika kuti vanosvotwa uye pick-pamusoro nokuveza chokushandisa.
9.Bars kuti vave tumafuta wakavhomorwa vari nyore muchina pane vari annealed ezvinhu.
10.Grade 430F, vakasununguka machine shanduro 430, zviri zvikuru nyore muchina.
11.Lower basa achiomesa mwero kunoita vachikotama nokuita rerukei kupfuura kugiredhi 304
12.Lower ductility rinokutadzisa kwazvo kushandiswa.
13.Severe Bends zvinofanira kuitwa pamwe chete vanobwembura akabatana ari pamakona kune rinopfungaira mirayiridzo yakarurama.
14.Severe chando unoti pane 430 waya zvinoita.
