Konpayi nou an angaje nan biznis ekspòtasyon asye kabòn ak asye alyaj.Tiyo alyaj, tiyo asye alyaj, Alloy Steel tiyo Lachin, tiyo kabòn, Kabòn Steel Tiyo, Kabòn Steel tiyo Lachin.
èske w konnen diferans ki genyen ant asye kabòn ak asye alyaj?
Kabòn asye:sitou refere a pwopriyete yo mekanik depann sou kontni an kabòn nan asye, epi jeneralman yo pa ajoute yon anpil nan eleman alyaj nan asye, pafwa yo rele plenn asye kabòn oswa asye kabòn. Kabòn asye, konnen tou kòm asye kabòn, kontni kabòn WC mwens pase 2% alyaj kabòn fè.
Kabòn asye anplis jeneralman gen yon ti kantite Silisyòm, Manganèz, souf, fosfò ka divize dapre itilizasyon kabòn asye kabòn estriktirèl asye, kabòn zouti asye ak gratis-koupe asye estriktirèl twa kabòn asye estriktirèl divize an asye estriktirèl ak machin asye estriktirèl, ki ka divize an asye kabòn ki ba (WC ≤ 0.25%), asye kabòn mwayen (WC 0.25% - 0.6%) ak asye kabòn segondè (WC> 0.6%).
Dapre kontni fosfò ak souf, asye kabòn yo ka divize an asye kabòn òdinè (fosfò ak souf yo pi wo), asye kabòn kalite siperyè (fosfò ak souf yo pi ba) -wo kalite asye (fosfò, souf pi ba).
Alyaj asye:ki baze sou kabòn asye, youn oswa plis eleman alyaj yo fè espre ajoute amelyore sèvis la ak pèfòmans pwosesis nan alyaj la ki baze sou fè yo rele asye alyaj. Asye alyaj refere a asye a ki gen Silisyòm ak Manganèz kòm eleman alyaj oswa eleman deoksidan, lòt eleman alyaj tankou Kwòm, nikèl, molybdène, vanadyòm, Titàn, kwiv, tengstèn, aliminyòm, cobalt, niobyòm, zirkonyòm ak lòt eleman, ak kèk tou. gen kèk eleman ki pa metal (tankou bor, nitwojèn, elatriye) asye.
Dapre kantite eleman alyaj nan asye, men tou, yo ka divize an asye alyaj ki ba, alyaj mwayen ak asye alyaj segondè.
Diferans konpozisyon chimik:
(1) Kabòn asye: Low kabòn asye (C≤0.25%); Mwayen kabòn asye (C≤0.25 ~ 0.60%); Segondè kabòn asye (C≤0.60%).
(2) Asye alyaj: Low alyaj asye (kontni total nan eleman alyaj ≤ 5%); Mwayen alyaj asye (kontni total nan eleman alyaj> 5 ~ 10%); Segondè alyaj asye (kontni total nan eleman alyaj> 10%.
Avantaj asye kabòn:
Kabòn asye gen gwo fòs, duktilite ak severite, pri ki ba, yo itilize nan machin lou pou fabrike pati chaj lou. Ka jwenn pa tretman chalè pi bon pwopriyete mekanik jete.
Avantaj asye alyaj:
Anplis de fè nan eleman asye ki gen sèlman asye kabòn, asye kabòn, lòt Silisyòm, souf, fosfò ak lòt enpurte. Anplis de lòt eleman nan chromium, Manganèz, molybdène, Titàn, tengstèn, vanadyòm, niobyòm, bor, Silisyòm ak nikèl alyaj asye reyalize pwopriyete yo vle tankou tanperati ki wo, segondè elastisite, rezistans fwotman, segondè fòs, segondè severite ak konsa sou. Alyaj asye dite mete rezistans, hardenability, rezistans korozyon pase asye kabòn ekselan.

3.Tès nondestructive
Plizyè kalite tès nondestructive ultrasons oswa elektwomayetik ki disponib. Tès yo dwe itilize ak limit enspeksyon yo dwe etabli pa akò manifakti ak achtè.
