Igwe anaghị agba nchara 316 (US ọkọlọtọ ASTM S31600, Chinese ọkọlọtọ 06Cr17Ni12Mo2) bụ molybdenum nwere austenitic igwe anaghị agba nchara, nke a na-akpọkarị "mmiri igwe anaghị agba nchara" n'ihi na ya magburu onwe corrosion nguzogide. Ọ dabere na igwe anaghị agba nchara 304 yana mgbakwunye nke 2-3% molybdenum (Mo), nke na-eme ka ọ dịkwuo elu n'iguzogide pitting na corrosion crevice.
Ⅰ. njirimara ndị isi
1.Exceptional corrosion Resistance: Mgbakwunye nke molybdenum na-enye ya arụmọrụ dị elu na gburugburu chloride (dịka, mmiri mmiri, nnu nnu), na-eguzogide nkwụsị nke karịrị nke 304 igwe anaghị agba nchara. Ọnụego corrosion ya na 10% sulfuric acid nwere ike ịbụ ihe na-erughị 0.1 mm / afọ.
2.High-Temperature Performance: Ezi okpomọkụ dị elu na nguzogide oxidation, na-arụ ọrụ okpomọkụ na-aga n'ihu ruo 870 ° C na ọrụ nkwụsịtụ ruo 925 ° C.
3.Mechanical Properties: ike mpụta ≥205 MPa, ike ike ≥515 MPa, elongation ≥40%, na-enye ike siri ike na ike ịrụ ọrụ.
4.Ọdịmma Magnetism: Na-abụghị magnetik na ngwọta-annealed ala; nwere ike ịghọ magnetik ka ọ rụchara ọrụ oyi. Kwesịrị ekwesị maka akụrụngwa nwere mmetụta maka oghere magnetik.

Ⅲ.Njirimara arụrụ arụ
Ngwongwo arụrụ arụ nrụnye okpomọkụ nke ime ụlọ (Solution-Annealed State)
Nke a bụ steeti a na-ahụkarị maka igwe anaghị agba nchara 316, na-enye ezigbo nguzozi nke akụrụngwa.
| Ngwongwo | Uru a na-ahụkarị | Ọkọlọtọ chọrọ (ASTM A240) |
| Ike tensile (Rm) | 515-620 MPa | ≥ 515 MPa |
| Ike Mpụta (Rp0.2) | 205-310 MPa | ≥ 205 MPa |

Ihe ndetu:
1.Moderate Ike: Mpụta ike gburugburu 200-300 MPa, na-eme ka ọ dị mfe ịmepụta na nhazi.
2.Excellent Plasticity: Elongation na-adịkarị karịa 40%, na-egosi oke ike na iguzogide mgbaji na-agbaji agbaji.
3. Ịrụ ọrụ ike: Ike na ike na-abawanye nke ukwuu n'oge ọrụ oyi (dịka ọmụmaatụ, ntụgharị oyi, ịbịaru), ma plasticity na-ebelata.
Ⅳ. Mpaghara ngwa ngwa
1.Marine Engineering: Ngwa ụgbọ mmiri, ikpo okwu dị n'ụsọ oké osimiri, ngwa ịsa mmiri.
2.Chemical & Energy Industries: Reactors, pipeline, okpomọkụ mgbanwe (na-eguzogide acid / alkalis).
3.Medical & Food Industries: Ngwa ịwa ahụ, akụrụngwa ọgwụ, igwe na-edozi nri (na-ezute ụkpụrụ ịdị ọcha).
4.Architecture & Decoration: Ụlọ mgbidi ákwà mgbochi, ụgbọ okporo ígwè na mpaghara ndị dị n'ụsọ oké osimiri (na-eguzogide ọgwụ corrosion nnu nnu).
ⅤKlas nke ewepụtara
316L: Ụdị carbon dị ala (C≤0.03%), mma weldability na intergranular corrosion resistance, dabara maka akụkụ welded dị arọ.
316H: Ụdị carbon dị elu, ike dị elu dị elu, nke kwesịrị ekwesị maka ihe ndị na-eme ka okpomọkụ dị elu.
