Biziň kompaniýamyz uglerod polatdan we garyndy polatdan eksport işi bilen meşgullanýar.Garyndy turba, lehimli polat turba, Garylan polat turba Hytaý, uglerod turbasy, Uglerod polat turbasy, Uglerod polat turbasy Hytaý.
Uglerod polat bilen garyndy poladyň arasyndaky tapawudy bilýärsiňizmi?
Uglerod polat:esasan poladyň uglerod düzümine bagly mehaniki häsiýetlere degişlidir we adatça ýönekeý uglerod polat ýa-da uglerod polat diýlip atlandyrylýan poladyň köp garyndy elementlerini goşmaýar. Uglerod polat, uglerod polat diýlip hem bilinýär, uglerodyň mukdary WC 2% -den az demir uglerod garyndysy.
Uglerod polatdan başga-da az mukdarda kremniý, marganes, kükürt, fosfor bar, uglerod polat uglerod polat, uglerod gural polat we erkin kesiş gurluş polat üç uglerod gurluş polat gurluş polata bölünýär we Pes uglerod polatdan (WC ≤ 0,25%), orta uglerod polatdan (WC 0,25% - 0,6%) we ýokary uglerod polatlaryndan (WC> 0.6%) bölünip bilinýän maşyn gurluş polat.
Fosfor we kükürdiň düzümine görä uglerod çelikleri adaty uglerod çeliklerine (fosfor we kükürt has ýokary), ýokary hilli uglerod çeliklerine (fosfor we kükürt pes) ýokary hilli polat (fosfor, kükürt aşaky) bölünip bilner.
Garyndy polat:uglerod polatdan ugur alyp, demir esasly garyndynyň hyzmat ediş ukybyny we işleýşini gowulandyrmak üçin bilgeşleýin bir ýa-da birnäçe garyndy elementleri goşulýar, garyndy polat diýilýär. Garyndy polat kremniý we marganes bolan polaty eritiji elementler ýa-da deoksidleşdiriji elementler, hrom, nikel, molibden, vanadiý, titanium, mis, wolfram, alýumin, kobalt, niobium, sirkonium we beýleki elementleri öz içine alýan polaty aňladýar. demir däl elementleri (bor, azot we ş.m.) öz içine alýar.
Polatdaky garyndy elementleriniň mukdaryna görä, pes erginli polatdan, orta garyndydan we ýokary garyndy polatdan hem bölünip bilner.
Himiki düzümiň tapawudy:
(1) Uglerod polat: Pes uglerod polat (C≤0,25%); Orta uglerod polat (C≤0.25 ~ 0.60%); Carbonokary uglerod polat (C≤0.60%).
(2) Garyndy polat: Pes garyndy polat (ergin elementleriniň umumy mazmuny ≤ 5%); Orta garyndy polat (garyndy elementleriniň umumy mazmuny> 5 ~ 10%); Highokary garyndy polat (garyndy elementleriniň umumy mazmuny> 10%.
Uglerod polat artykmaçlyklary:
Uglerod polat ýokary güýç, süýümlilik we berklik, agyr ýük bölekleri öndürmek üçin agyr tehnikalarda ulanylýar. Heatylylygy bejermek arkaly has gowy mehaniki häsiýetleri guýup bolýar.
Garylan polat artykmaçlyklary:
Diňe uglerod polat, uglerod polat, beýleki kremniý, kükürt, fosfor we beýleki hapalary öz içine alýan polat elementlerindäki demirden başga. Highokary temperatura, ýokary çeýeligi, aşgazana garşylygy, ýokary güýji, ýokary berkligi we ş.m. ýaly islenýän häsiýetlere ýetmek üçin hrom, marganes, molibden, titanium, wolfram, vanadiý, niobium, bor, kremniý we nikel garyndy poladynyň beýleki elementlerinden başga-da üstünde. Garyndy polat gatylygy kömür polatdan has oňat garşylyk, gatylyk, poslama garşylyk.
