Hais txog H13 STEEL

Sij hawm: 2022-06-17 Hits: 99

KONSOND yog ib tug ntawm cov saum toj kawg nkaus H13 steel Chaw tsim tshuaj paus thiab Exporter Tuam Tshoj, peb yuav muab nrog round, square, ca, thaiv, thiab ncej thiab lwm yam. H13 steel yog ib tug chromium-molybdenum-vanadium kub ua hauj lwm cuab tam steel raws li ib tug ASTM A681 txuj. Kev ua haujlwm zoo rau kev puas tsuaj ntawm qhov kub thiab txias, zoo toughness, thiab zoo tiv thaiv thermal fatigue cracking (tseem hu ua tshav kub xyuas). txwv distortion thaum lub sij hawm hardening.



Cov yam ntxwv tseem ceeb ntawm H13 steel yog:


High hardenability thiab siab toughness.

Zoo heev tiv thaiv thermal cracking, uas tuaj yeem ua dej txias hauv chaw ua haujlwm.

Kev hnav tsis zoo rau kev hnav, thiab cov txheej txheem carburizing lossis nitriding tuaj yeem siv los ua kom nws nto 

hardness, tab sis nrog ib tug me ntsis txo nyob rau hauv tsis kam mus thermal cracking.

Tsis zoo theem nrab hardening muaj peev xwm nyob rau hauv tempering vim nws cov ntsiab lus carbon tsawg.

tsis kam mus softening ntawm qhov kub thiab txias, tab sis ib tug sai poob nyob rau hauv hardness tshwm sim ntawm kev khiav hauj lwm 

kub siab tshaj 540 ° C (1000 ° F) (piv txwv li, kev ua haujlwm kub uas tuaj yeem zam tau yog 540 ° C).


Tsawg kub kho deformation.

Nruab nrab thiab siab machinability.

Nruab nrab tsis kam mus decarburization.

Qhov tshwj xeeb tshaj yog, nws tuaj yeem siv los ua cov khoom tseem ceeb hauv kev lag luam aerospace.

FAQ txog H13 STEEL

H13 STEEL yog dab tsi?

H13 steel yog ib hom high tensile lub zog uas tsis tshua muaj alloy structural steel. H13 steels yog tsim los ua kev lag luam, 

qis zog lwm txoj rau H11 thiab H22 qib hauv feem ntau daim ntawv thov. ASTM International specification rau 

Qib H13 yog A572 / A572M-10. H13 steel muaj qhov tsawg kawg nkaus lub zog ntawm 55,000 psi thiab tsis tas yuav tsum muaj zinc txheej. 

H13 steels feem ntau yog tsim nyob rau hauv kub dov los yog txias-tiav tej yam kev mob nyob ntawm seb yuav tsum tau daim ntawv thov. 

H11 yog ib qho kev hloov kho tshiab los ntawm qib H14 nrog cov khoom siv kho kom zoo dua qub tab sis zoo sib xws weldability rau qib H14.


QHOV CHAW UA HAUJ LWM rau H13 STEEL yog dab tsi?

H13 steel tuaj yeem siv tau qhov chaw siab zog yuav tsum tau ua tom qab kev ua haujlwm nruab nrab ua tiav 

thaum zam cov nqi tseem ceeb ntxiv uas yuav ua rau yog tias cov khoom siv alloying kim dua ntxiv. 

Qhov no txhais tau hais tias nws muaj txiaj ntsig zoo hauv kev siv tsheb, lub zog, couplings / coupling shafts nrog rau lwm yam 

Cheebtsam koom nrog hauv tsheb thoob plaws ntau qhov kev lag luam suav nrog aerospace & tiv thaiv, 

hnyav engineering thiab khoom siv ua liaj ua teb. H13 steel kuj tseem siv rau hauv kev tsim cov tsheb ciav hlau 

taug qab cov khoom xws li keyboards, hla thiab cov ntsiab lus.


Cov txiaj ntsig ntawm H13 STEEL yog dab tsi?

H13 steels muab zoo toughness ua ke nrog zoo heev weldability thiab formability ua rau nws ib tug nrov xaiv rau 

ntau fabricators. Nws tuaj yeem ua tau yooj yim machined kom kaw qhov siab ntev thiab muaj kev tiv thaiv zoo rau hnav, tsim kua muag thiab qaug zog 

ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv nyob rau hauv qhov chaw muaj kev ntxhov siab. Kev sib xyaw ua ke ntawm lub zog thiab toughness ua 

H13 steel haum rau ob qho tib si daim ntaub ntawv zoo li qub (qhov twg loads tsis hloov) thiab dynamic applications (qhov twg loads fluctuate).


Puas muaj tej yam tsis zoo rau kev siv H13 STEEL?

Ib qho teeb meem uas muaj peev xwm yuav yog nws qhov kev raug rau hydrogen embrittlement. H13 steel yog qhov cuam tshuam rau kev tawg 

nyob rau hauv lub tshav kub cuam tshuam cheeb tsam vim lub alloy tsis muaj chromium cov ntsiab lus thiab yog li ntawd, tej zaum yuav muaj teeb meem nrog ib co 

welding txheej txheem suav nrog submerged arc vuam (SAW) lossis roj hlau arc vuam (GMAW). 

H13 steels kuj tsuas yog muaj txog li qhov siab tshaj plaws ntawm 12 hli vim nws lub zog dhau los ua qhov txwv 

dhau qhov no. Lwm qhov teeb meem tuaj yeem yog qhov H13 steel qib tsis suav nrog feem pua ​​​​cov pa roj carbon 

ntau yam uas yuav pab tau cov neeg siv kawg / vuam los txiav txim seb lawv daim ntawv thov xav tau H11 lossis H22 qib alloys 

tsis yog H13.


Puas yog H13 CORROSION RESISTANT?

H13 tsis yog corrosion resistant thiab yog li ntawd, tej zaum yuav xav tau ib txheej yog siv nyob rau hauv ib puag ncig qhov twg 

nws yuav raug corrosive hais.


H13 QIB sib npaug yog dab tsi?

Qhov ze tshaj H13 qib sib npaug yuav yog H11 lossis H22 alloys uas muaj cov tshuaj lom neeg zoo sib xws 

tab sis muaj cov khoom siv kho tshuab zoo dua. 

Yog tias xav tau qib siab zog, ces H14 lossis H19 qib yuav tsum raug txiav txim siab.


Qhov txawv ntawm H13 thiab lwm yam hlau qib yog dab tsi?

Qhov sib txawv tseem ceeb ntawm H13 thiab lwm qib steel yog nws cov ntsiab lus chromium qis uas ua rau nws muaj kev cuam tshuam ntau dua. 

tawg thaum welding. 

Nws kuj muaj zoo heev toughness thiab weldability ua rau nws ib tug nrov kev xaiv rau ntau fabricators. 

Lwm cov qib steel xws li H11, 

H14 thiab H19 muaj zog ntau dua tab sis tej zaum yuav tsis yog tawv los yog weldable.


H13 STEEL yog dab tsi?

Qhov tsawg kawg nkaus yield zog rau H13 steel yog 55,000 psi.


Puas yog H13 Qib muaj nyob hauv STAINLESS STEEL?

Tsis yog, qib H13 tsuas yog muaj nyob rau hauv carbon steel alloys. 

Yog tias yuav tsum muaj cov hlau tsis muaj steel hlau, ces 304 lossis 316 qib yuav tsum tau txiav txim siab.


Kuv tuaj yeem tau txais cov ntaub ntawv ntxiv ntawm H13 STEEL qhov twg?

Yog xav paub ntxiv txog ASTM International cov qauv H13 steel qib, 

H11 qib lossis H22 qib steels koj tuaj yeem mus ntsib AST International lub vev xaib. Yog xav paub ntxiv txog H13 steel zog,
