2025-06-12
Bayani: QN1803 (kuma ana kiransa 304D ko aji 1.4376) sabon ƙera bakin karfe ne na austenitic daga Tsingshan/Qingtuo. An ƙirƙira shi da babban nitrogen, babban chromium da jan ƙarfe, da rage abun ciki na nickel don isar da shi mafi girma ƙarfi da lalata juriya a ƙananan farashifiye da daidaitattun 304. An kwatanta QN1803 a matsayin "madaidaicin farashi mai tsada ga gargajiya 304 Bakin Karfe,” hadaya"Mafi girman juriya na lalata, ƙarfi mai ƙarfi, da kyakkyawan juriya na lalacewa". Babban tsarin sa na nitrogen, ƙarancin nickel yana rage farashin gami ba tare da lalata aikin ba. Garin yana da sauƙin sarrafawa da waldawa, kuma ya dace da ƙa'idodin ƙasa da ƙasa da takaddun shaidar ingancin abinci, wanda ya sa ya dace da fitarwa zuwa duniya.
High-Nitrogen, Nickel-Saving Alloy Composition
Chemistry na QN1803 an keɓance shi don aiki da ƙimar farashi. Ya ƙunshi Cr 17.5-19.5%, Da 1.0-3.5%, kuma N 0.20-0.30%, tare da Ba ma kawai 2.0-3.5% (kamar ~ 8% a cikin 304). Sabanin haka, 304 karfe shine ~ 18% Cr, 8% Ni, ~ 0.045% N, kuma kawai ~ 0.1% Cu. Ƙarin nitrogen da chromium suna haɓaka ƙarfi da juriya, yayin da aka ƙara jan ƙarfe yana ba da kaddarorin ƙwayoyin cuta da ingantaccen tsari. Ƙananan abun ciki na nickel (da matsakaicin manganese) yana rage farashin kayan aiki sosai. A takaice, QN1803's babban-Ni-tsara dabara yana haifar da bakin karfe tare da lalata da halayen injina daidai da ko mafi kyau fiye da 304 a farashi mai ƙarancin gami.
