Yadda za a zabi bakin karfe

Akwai manyan abubuwa guda uku da ke shafar lalata bakin karfe a ƙasa:

1.Abubuwan da ke cikin alloying, gabaɗaya magana, abun ciki na chromium a cikin 10.5% ƙarfe ba zai yi tsatsa cikin sauƙi ba.

Mafi girman abun ciki na chromium da nickel, mafi kyawun juriya na lalata.Misali,

abun ciki na nickel a cikin kayan 304 shine 8-10%, kuma abun ciki na chromium ya kai 18-20%.

Irin wannan bakin karfe ba zai yi tsatsa a karkashin yanayi na al'ada ba.

2.Tsarin narkewa na masana'anta kuma zai shafi juriyar lalata na bakin karfe.

Babban shukar bakin karfe tare da fasaha mai kyau na narkewa,

kayan aiki na ci gaba da fasaha na ci gaba na iya ba da garantin sarrafa abubuwan alloying,

kawar da datti, da kuma kula da yanayin sanyi na billet,

don haka ingancin samfurin yana da kwanciyar hankali kuma abin dogara, ingancin ciki yana da kyau, kuma ba shi da sauƙi ga tsatsa.Akasin haka,

wasu ƙananan masana'antun ƙarfe suna da kayan aiki da fasaha na baya.A lokacin aikin narkewar,

Ba za a iya cire ƙazanta ba, kuma samfuran da aka samar za su yi tsatsa ba makawa.

3.Yanayin waje, yanayin bushe da iska ba shi da sauƙi ga tsatsa.Duk da haka,

zafi na iska yana da girma, ci gaba da yanayin ruwan sama, ko yanayin da ke da babban pH a cikin iska yana da sauƙi ga tsatsa.

304 bakin karfe, idan yanayin da ke kewaye ya yi muni sosai, zai yi tsatsa.

Yawancin abokan ciniki suna zuwa kasuwa don siyan bakin karfe kuma su kawo ƙaramin maganadisu tare da su.

Idan babu maganadisu, ba za a sami tsatsa ba.A gaskiya, wannan rashin fahimta ce.

Tasirin bakin karfe ba na maganadisu ba yana ƙaddara ta tsarin tsarin.

A lokacin aikin ƙarfafawa, narkakkar karfe zai samar da "ferrite", "austenite",

"Martensite" da sauran bakin karfe tare da sassa daban-daban.Tsakanin su,

Bakin karfe na “ferrite” “Jiki” da “Martensitic” duk magnetic ne.

"Austenitic" bakin karfe yana da kyawawan kaddarorin inji,

aiwatar da aiki da weldability, amma kawai cikin sharuddan lalata juriya,

Magnetic “ferritic” bakin karfe ya fi karfin “austenitic” bakin karfe.

A halin yanzu, da ake kira 200 jerin da 300 jerin bakin karfe da high

Abubuwan da ke cikin manganese da ƙananan abun ciki na nickel a kasuwa ba su da maganadisu,

amma aikinsu ya sha bamban da na 304 tare da babban abun ciki na nickel.Maimakon haka,

304 an miƙe, an rufe, goge, da jefar.Tsarin magani kuma zai zama micro-magnetic,

don haka rashin fahimta ne da rashin kimiyya a yi hukunci da ingancin bakin karfe ba tare da maganadisu ba.
