High- steel phaj muaj zog tuaj ntau qib: Q460, Gr65, YAW, TEN60, E460CDE. Hauv qib 460, "Q" sawv cev rau lub zog tawm los, thiab "460" qhia qhov qis qis ntawm 460 MPa rau lub zog tawm los. Hom hlau no txhim kho nws qhov kev ua tau zoo tag nrho los ntawm kev ntxiv cov kab ke xws li niobium thiab vanadium, ua kom nws lub zog tensile los ntawm kwv yees li 30% piv rau cov pa roj carbon zoo tib yam. Nws yog dav siv nyob rau hauv engineering machinery, lub tsev tsim, thiab choj load{12}}cov kabmob Cheebtsam.

Hais txog cov khoom siv, Q460 steel phaj muaj nyob rau hauv thickness ntawm 5-150 hli thiab dav txog 3800 hli. Cov tshuaj muaj pes tsawg leeg suav nrog cov ntsiab lus carbon tswj qis dua 0.18%, manganese cov ntsiab lus ntawm 1.00-1.60%, thiab cov ntsiab lus sulfur thiab phosphorus tsis tshaj 0.025%. Nyob rau hauv cov nqe lus ntawm txhua yam khoom, lub zog tensile ncav cuag 550-720 MPa, lub elongation tsis tsawg tshaj li 17%, thiab lub zog cuam tshuam ntawm -40℃yog guaranteed siab tshaj 34 Joules. Kev kho deg tuaj yeem xaiv los ntawm kub-kuav los tiag, tswj-dov, lossis lub xeev normalized, nrog rau kev kho mob sib txawv nyob ntawm daim ntawv thov ib puag ncig.

Siab zog

Ordinary siab- lub zog steel daim hlau muaj qhov tensile qis lossis lub zog tawm los, lossis tuaj yeem tsim tau siv cov txheej txheem ib txwm muaj lossis nrog kev hloov kho me ntsis. Piv txwv muaj xws li ci- cov phaj hlau tawv tawv, phosphorus- muaj cov phaj hlau, siab- lub zog IF steel phaj, thiab HSLA steel phaj. Advanced high -lub zog steel daim hlau xav tau cov cuab yeej siv siab heev thiab cov txheej txheem los tsim, xws li dual-phase steel daim hlau (DP steel phaj), complex-phase steel daim hlau (CP steel daim hlau), kev hloov pauv-induced plasticity steel daim hlau (TRIP steel daim hlau), thiab martensitic steel daim hlau (M steel daim hlau lossis Mart steel daim hlau).

Cov khoom lag luam txaus

Advanced high -lub zog steel, luv luv li AHSS, tau muab faib ua ob pawg hauv qhov thib peb tsab ntawm International Iron thiab Steel Institute (IISI) Phau Ntawv Qhia rau Kev Siv Siab Siab -Strength Steel: Pa HSS thiab Advanced High-Strength Steel (AHSS). AHSS feem ntau suav nrog duplex (DP) steel, transformation-induced plasticity (TRIP) steel, martensitic (M) steel, multiphase (CP) steel, kub-formed (HF) steel, thiab ntxaib-inducing plasticity (TWIP) steel. AHSS muaj lub zog nruab nrab ntawm 500 MPa thiab 1500 MPa, nthuav tawm lub zog nqus tau zoo, thiab ua lub luag haujlwm tseem ceeb hauv kev tsim kho tsheb thiab kev nyab xeeb. Nws yog dav siv hauv kev lag luam tsheb, feem ntau hauv cov khoom siv, cov khoom siv kev nyab xeeb, thiab cov khoom siv ntxiv xws li A / B / C pillars, qhov rooj sills, pem hauv ntej thiab rear bumpers, qhov rooj tiv thaiv - kev sib tsoo kab teeb, crossbeams, longitudinal beams, thiab rooj zaum rails. DP steel yog thawj pawg- tsim tawm xyoo 1983 los ntawm SSAB Steel Sheet GmbH hauv Sweden.

Saib xyuas kom meej

High-lub zog thiab siab- ductility steel (TRIP) suav nrog kub- dov, txias- dov, electroplated, thiab kub-dip galvanized khoom. Nws lub ntsiab microstructure muaj ferrite, bainite, thiab khaws cia austenite, nrog rau cov ntsiab lus khaws cia austenite li ntawm 5% mus rau 15%. Nws lub zog yog 600-800 MPa. Siab -lub zog steel ua kom pom qhov siab elongation. Piv nrog rau DP steel, TRIP steel muaj qhov qis dua thawj zaug ua haujlwm hardening Performance index, tab sis nws cov kev ua haujlwm hardening Performance index tseem siab dhau ntawm qhov ntev ntev, ua rau nws tshwj xeeb tshaj yog tsim rau bulging forming. Cov khoom tseem ceeb ntawm TRIP steel yog C, Si, thiab Mn. Si feem ntau inhibits cementite nag lossis daus thaum lub sij hawm bainite transformation, tab sis nws yog detrimental rau qhov zoo ntawm cov ntawv hlau.

Lub ntsiab txhais ntawm "ultra- siab zog steel" hloov nrog cov qib ntawm kev nce qib thev naus laus zis xav tau los ntawm lub sijhawm. Feem ntau hais lus, alloy steel nrog lub zog tawm ntawm 1370 MPa (140 kgf / mm2) lossis siab dua thiab lub zog tensile ntawm 1620 MPa (165 kgf / mm2) lossis siab dua yog hu ua ultra- siab zog steel. Raws li nws cov qib alloying thiab microstructure, nws tau faib ua qis- alloy nruab nrab-carbon martensitic ntxiv dag zog rau ultra- siab zog steel, nruab nrab- alloy nruab nrab-carbon Secondary nag lossis daus hardening ultra{15}} siab zog steel, siab- alloy nruab nrab-carbon Ni-Co hom ultra- siab zog steel, ultra- qis-carbon martensitic hnub nyoog hardening ultra- siab zog steel, thiab semi- austenitic nag lossis daus hardening stainless hlau, thiab lwm yam.
