Halabuurka Kiimikada
Birta la heli karo ee DIN TstE500 ee cabbirka saxanka birta: dhumucda ≤ 650 mm, ballac ≤ 4500 mm, dhererka ≤ 18000 mm. Taarikada birta ka weyn ayaa sidoo kale la heli karaa haddii la codsado. Saxankeena birta ah ee DIN TstE500 waxaa lagu bixin karaa iyadoo loo eegayo heerka Shiinaha, heerka American AISI / ASME / ASTM, Japanese JIS, German standard DIN, French NF, British BS, European EN, ISO caalami ah iyo heerar kale. Habka daawaynta kulaylka: rogid la xakameeyey, caadi ka dhigid, xamaasad, caadiyaynta iyo xanaaqa, xanaaqa, iwm.
Saxan bir ah DIN TstE500 goynta saxan bir ah, sida waafaqsan heerarka kala soocidda kala duwan, waxaa jira noocyo kala duwan oo gaar ah. Haddii loo qaybiyo heerkul goynta, waxa loo qaybin karaa goyn qabow iyo goyn kulul. Waxaa ka mid ah, goynta qabow, sida goynta jet-biyoodka iyo goynta abrasive, goynta kulul waa goynta ololka, goynta balaasmaha iyo goynta laysarka. Intaa waxaa dheer, waxaan sidoo kale u baahannahay inaan ogaano in xaashida birta ee DIN TstE500 ee dhumucdeedu sareeyso lagu goyn karo olol, gooynteeduna waa mid fudud sida birta yar ee kaarboon-yar ee caadiga ah, laakiin fiiro gaar ah ayaa loo baahan yahay.
Fosfooraska waa shay aad u dhib badan oo ku jira saxan bir ah DIN TstE500. Kordhinta maadada fosfooraska, xoogga, dabacsanaanta iyo adkaanta saxanka birta ee DIN TstE500 ayaa kordha, laakiin caagga iyo adkaanta ayaa si weyn hoos ugu dhacaysa. Gaar ahaan, heerkulku hooseeyo, weynaanta saamaynta balaastikada iyo adkaanta, kordhinta jilicsanaanta qabow ee birta.
