Haɗu da Iyalin Bakin Karfe

Bakin karfe shine ainihin masu ɗaukar fansa na ƙarfe: baƙin ƙarfe, chromium, nickel-da ƴan ƴan gefe-haɗe-haɗe don ƙarfin yaƙi da lalata. Amma ya danganta da adadin nickel da ke tare don hawan, fatar ku na iya ko dai ta ba da mamaki ko kuma wani babban yatsa. Mu hadu da masu fafatawa:
1. 1. Nau'i na 304
  - Jeri: 18-20% chromium + 8-10.5% nickel
  - Babban ƙarfi: Stellar tsatsa juriya da tsari
  - Kryptonite: Wannan kaso na nickel na iya zubowa a ƙarƙashin gumi kuma ya haifar da tawaye mai zafi a wuyan hannu
2. 2.Nau'in 316L (ƙananan carbon, ultra-taushi dan uwan)
  - Jeri: 16-18% chromium + 10-14% nickel + 2-3% molybdenum
  - Babban ƙarfi: Molybdenum yana kulle sakin nickel kamar Fort Knox - ko da feshin teku ba zai iya lalata shi ba.
  - Matsayin Jarumi: An haɗe shi a cikin suites ɗin tiyata da wuraren huda jiki - fata mai raɗaɗi na nickel yana ba shi a tsaye.

316L vs. 316: Menene Bambancin?

316L da 316 bakin karfe suna kama da sinadarai - duka biyun austenitic gami da chromium, nickel, da molybdenum. Babban bambanci shine abun ciki na carbon:

Carbon: 316L ya ƙunshi ≤0.03% carbon, yayin da 316 na iya samun har zuwa 0.08%. Wannan ƙananan carbon yana rage yiwuwar samuwar chromium carbide a lokacin walda.
Weldability: 316L ƙaramar hazo na carbide yana nufin kusan babu wayewar bayan walda, don haka wuraren da aka weld sun kasance masu jure lalata. Sabanin haka, welded 316 na iya haɓaka “lalacewar walda” ba tare da ingantaccen maganin zafi ba.
Juriya na Lalata: Dukansu karafa suna tsayayya da lalata da kyau, amma 316L ya fi girma a cikin yanayin chloride da bayan walda. Welded 316 ya fi dacewa da tsatsa a cikin yankunan da zafi ya shafa.
Ƙarfi: Saboda ƙarin carbon, 316 wani lokacin yana da ɗan ƙaramin ƙarfi mai ƙarfi / ƙarfin samarwa fiye da 316L. A aikace wannan bambanci kadan ne. A yawancin aikace-aikace (ciki har da ƙira mai nauyi da amfani da tsari), ƙarfin 316L yana da yawa.
Yawan Amfani: Gabaɗaya, an zaɓi 316L don marine, sinadarai, da likitanci aikace-aikace inda ake buƙatar matsakaicin juriya na lalata da weldability. Ana yawan amfani da Standard 316 a ciki masana'antu, sarrafa abinci, da gine-gine na gaba ɗaya inda walda ba ta da yawa ko kuma matsanancin lalata ba abu bane.
