Iye zvino zvigadzirwa zvakawanda zvemaindasitiri zvichagadzirwa nesimbi isina tsvina yetambo zvinhu.Kuti uone iyo fake uye yakaderera simbi isina tsvina, mamwe matanho uye nzira dzinogona kutorwa.Asi vatengi vazhinji havazive nzira yekuziva, vakanyora nzira dzinotevera dzekukuzivisa iwe.
Magnetic test method ndiyo yepakutanga yakajairika musiyano pakati pe austenitic Stainless simbi uye ferritic Stainless simbi yakapusa nzira, austenitic Stainless simbi isiriyo yemagineti simbi, asi mushure mekutonhora kugadziridzwa pasi pekumanikidza kukuru kuchava nediki magineti;Asi yakachena chrome simbi uye yakaderera alloy simbi yakasimba magineti simbi.
Hunhu hunoshamisa hwetambo yesimbi isina tsvina ndeyekupokana kwayo kwegora kune concentrated nitric acid uye dilute nitric acid, izvo zvinoita kuti zvive nyore kusiyaniswa kubva kune akawanda mamwe simbi kana alloys.Asi high carbon 420 uye 440 simbi munitric acid point test yakasvibiswa zvishoma, isiri-ferrous simbi inosangana yakanyura nitric acid inobva yaita ngura, uye dilute nitric acid ine corrosion yakasimba pa carbon steel.
Copper sulfate point test inzira iri nyore yekukurumidza kusiyanisa yakajairwa kabhoni simbi uye ese marudzi estainless simbi waya tambo.Iko kusanganiswa kwemhangura sulfate solution inoshandiswa ndeye 5% -10%.Pamberi pekuyedzwa kwepoindi, nzvimbo yekuyedza inofanira kunyatsobviswa kubva mumafuta kana kumwe kusvibiswa, uye nzvimbo diki inofanirwa kukwenenzverwa nemuchina wekukuya kana jira rakapfava rekukuya, uye ipapo mvura yekuyedza inodonha ichienda kunzvimbo yekukuya.Kazhinji kabhoni simbi kana simbi mumasekonzi mashoma ichaita mutsetse wekunze simbi mhangura, uye pamusoro pesimbi isina tsvina haiburitse kunaya kwemhangura kana kuratidza ruvara rwemhangura.
