Common qib ntawm lub zog siab structural steel
Nyob zoo ~ Hnub no kuv yuav qhia rau koj paub cov qib uas nquag siv ntawm cov qauv hlau muaj zog ~
Low-alloy high-strength structural steel yog tsim los ntawm kev ntxiv me me ntawm alloying ntsiab rau carbon structural steel (Wc = 0.16% ~ 0.2%).Nws txoj kev xaiv yog qhov pib zoo ib yam li cov khoom siv carbon steel.Yog li dab tsi yog tus lej tseem ceeb hauv tebchaws?

Cov qib siv feem ntau ntawm lub teb chaws tus qauv high-strength steel yog Q420B, Q460C, Q550D, Q690D, Q890D, thiab Q960E.

High-strength structural steel muaj Q + naj npawb + zoo qib cim + deoxidation qauv cim."Q" sawv cev rau qhov taw tes tawm ntawm cov hlau, thiab tus nqi nruab nrab sawv cev rau tus nqi ntawm qhov taw tes tawm, thiab chav tsev yog MPa.Piv txwv li, Q420B txhais tau hais tias qhov kev tawm dag zog (σs) yog 420 MPa, thiab qib B yog qib B structural steel.Q420 qib suav nrog qib B, C, D, thiab E, thiab cov xwm txheej xa khoom muaj xws li kub dov, normalizing, normalizing dov, thiab kub mechanical dov (TMCP).

Lub hom phiaj tseem ceeb
High-strength structural steel muaj lub zog siab, zoo plasticity thiab vuam kev ua tau zoo, thiab yog siv dav hauv kev tsim cov hlau thiab welded structural seem ntawm hlau ntauwd steel qauv, txuas hniav, tshuaj, mining, engineering machinery thiab lwm yam khoom siv;Nws kuj tuaj yeem siv rau hauv kev tsuas thiab ntau yam khoom siv hauv kev tsim kho engineering, xws li drilling rigs, hluav taws xob shovels, hluav taws xob log tsheb thauj khoom, excavators, loaders, bulldozers, qhob twj tso kua mis tsheb, hluav taws ntaiv, ntau yam cranes thiab thee mine hydraulic txhawb, thiab lwm yam. .
