Bakin Karfe 316 (US misali ASTM S31600, Sin misali 06Cr17Ni12Mo2) wani molybdenum-dauke da austenitic bakin karfe, sau da yawa ake magana a kai a matsayin "marine-grade bakin karfe" saboda da kyakkyawan lalata juriya. Ya dogara ne akan bakin karfe 304 tare da ƙari na 2-3% molybdenum (Mo), wanda ke haɓaka juriya ga lalata da ɓarna.
Ⅰ.Halayen Maɓalli
1.Exceptional Corrosion Resistance: Ƙarin molybdenum yana ba shi kyakkyawan aiki a cikin mahallin chloride (misali, ruwan teku, gishiri), tare da juriya mai zurfi fiye da na 304 bakin karfe. Adadin lalatarsa a cikin 10% sulfuric acid zai iya zama ƙasa da 0.1 mm / shekara.
2.High-Temperature Performance: Kyakkyawan ƙarfin zafin jiki mai ƙarfi da juriya na iskar shaka, tare da ci gaba da zafin sabis har zuwa 870 ° C da sabis na tsaka-tsaki har zuwa 925 ° C.
3.Mechanical Properties: Ƙarfin Ƙarfin ≥205 MPa, Ƙarfin Ƙarfin Ƙarfi ≥515 MPa, elongation ≥40%, yana ba da kyakkyawan ƙarfi da ƙarfin aiki.
4. Rashin Magnetism: Ba-magantakanci a cikin bayani-annealed jihar; na iya zama ɗan magnetic bayan aikin sanyi. Ya dace da kayan aiki masu kula da filayen maganadisu.
Ⅱ.Haɗin Sinadari (Masu Maɓalli)
| Abun ciki | Rage abun ciki | Aiki |
| Carbon (C) | ≤0.08% | Yana sarrafa lalatawar intergranular |

| Nickel (Ni) | 10.0-14.0% | Yana daidaita tsarin austenitic, juriya acid |
| Molybdenum (Mo). | 2.0-3.0%. | Core element, yana ba da juriya ga rami |
| Manganese (Mn) | ≤2.00% | Deoxidizer |
| Silicon (Si) | ≤0.75% | Deoxidizer |
Ⅲ.Abubuwan Halayen Injiniya Na Musamman
Kayayyakin Injiniyan Zazzabi na ɗaki (Jihar da aka cire Magani)
Wannan shine mafi yawan al'ada don 316 bakin karfe, yana ba da ma'auni mai kyau na kaddarorin.
| Dukiya | Mahimmanci Na Musamman | Matsayin Bukatun (ASTM A240) |
| Ƙarfin Tensile (Rm) | 515-620 MPa | ≥ 515 MPa |
| Ƙarfin Haɓaka (Rp0.2) | 205-310 MPa | ≥ 205 MPa |
| Tsawaita (A) | 40% - 50% | ≥ 40% |
| Hardness (HBW) | 149-217 | ≤ 217 |
| Modul na roba (E) | 193 GPA | - |
Bayanan kula:
1.Matsakaicin Ƙarfi: Ƙarfin Ƙarfin Ƙarfin Ƙarfi a kusa da 200-300 MPa, yana sauƙaƙa don samar da tsari.
2.Madalla da Plasticity: Elongation yawanci sama da 40%, yana nuna babban tauri da juriya ga karaya.
3. Yin aiki tukuru: Ƙarfi da taurin suna ƙaruwa sosai yayin aikin sanyi (misali, mirgina sanyi, zane), amma filastik yana raguwa.
Ⅳ.Firamare na Aikace-aikace
1. Injiniyan Ruwa: Kayan aikin jirgin ruwa, dandamali na ketare, kayan aikin lalata.
2.Chemical & Energy Industries: Reactors, pipelines, masu musayar zafi (mai tsayayya ga acid / alkalis).
3.Medical & Food Industries: Kayan aikin tiyata, kayan aikin magunguna, injin sarrafa abinci (ya dace da ka'idojin tsabta).
4.Architecture & Ado: Gina bangon labule, dogo a yankunan bakin teku (mai tsayayya da lalatawar gishiri).
Ⅴ.Darajojin Da Aka Samu Na kowa
316l: Low-carbon version (C≤0.03%), mafi kyau weldability da intergranular lalata juriya, dace da nauyi-sashe welded aka gyara.
316H: High-carbon version, mafi girma high-zazzabi ƙarfi, dace da high-zazzabi matsi-hala Tsarin.
