9xc steel belongs rau cov cuab yeej hom, uas yog tus yam ntxwv los ntawm ob yam ntxwv: siab hardness thiab zoo heev zoo nyob rau hauv cov nqe lus ntawm lub zog. Cov no thiab lwm yam nta yog vim lub fact tias cov cuab yeej muaj ib tug tshwj xeeb alloy muaj pes tsawg leeg, thiab kuj yog ua los ntawm cov txheej txheem tshwj xeeb.

Key Features

Metallurgical tuam txhab tam sim no tsim ntau ntau hom hlau sib txawv. Cov yam ntxwv ntawm steel 9xs coj mus rau qhov tseeb hais tias nws kuj belongs rau cov cuab yeej hom, thiab lub ntsiab feature yog cov ntsiab lus ntawm chromium thiab silicon nyob rau hauv lub composition. Daim ntawv thov tseem ceeb ntawm qib steel no yog tsim cov khoom siv rau kev ntsuas, nrog rau kev txiav thiab riam ntau lawm. Feem ntau siv rau cov khoom xws li tuag, reamers thiab combs.

Kev ua haujlwm siab thiab cov yam ntxwv ntawm cov neeg kho tshuab tau ua rau lub fact tias cov hlau tau nquag siv rau kev tsim cov khoom thiab cov khoom uas xav tau siab ua rau hnav tsis kam, khoov tsis kam thiab elasticity.

zoo zoo

riam ua los ntawm 9xc steelyog tsim los ntawm qhov tseeb tias nws muaj qhov zoo hauv qab no:

• Kev faib cov carbide hauv qib ntawm cov hlau no dhau ntawm tag nrho cov hlaws yog qhov sib xws. Qhov zoo no ua rau nws muaj peev xwm tsim cov cuab yeej threading nrog cov xov zoo zoo.
• Lwm qhov zoo dua yog tias qib ntawm cov hlau siv los ua cov riam yog qhov tiv taus tawg.
• Lwm qhov tshwj xeeb yog tias nyob rau hauv lub xeev annealed, nce hardness ntawm no alloy yog manifested. Tsis tas li ntawd, nws yog qhov yooj yim heev rau amenable rau xws li kev ua haujlwm xws li calcination thiab yog tus cwj pwm los ntawm kev ua kom sov. Tib yam zoo yog muaj nyob rau hauv riam ua los ntawm cov khoom no.

Alloy structure

Cov khoom xyaw ntawm 9xc steel suav nrog ntau cov ntsiab lus alloying. Ib qho ntawm cov ntsiab lus tseem ceeb yog chromium, cov ntsiab lus ntau ntawm uas nyob ntawm 0.95% mus rau 1.25%. Lub xub ntiag ntawm cov khoom no tsub kom xws li ib tug parameter li lub zog thiab hardness. Tsis tas li ntawd, chromium zoo heev txhim kho corrosion kuj. Silicon, uas tseem muaj nyob rau hauv cov khoom, muaj cov khoom zoo sib xws, thiab nws cov ntsiab lus yog ntau tshaj 1%. Txawm li cas los xij, nws tsim nyog sau cia tias vim nws, plasticity thiab viscosity tau txo qis me ntsis. Txawm li cas los xij, nws muaj peev xwm ua kom qhov pib ntawm cov yam ntxwv xws li txias brittleness thiab nce qhov pib tawm los.

kho cua sov thiab tshuaj xyuas

Cov txheej txheem kho cua sov rau 9xc steel siv qhov chaw hauv hluav taws xob rauv taws. HauvLub sijhawm ntawm cov txheej txheem no, koj yuav tsum ua raws li hauv qab no:

• tswj qhov kub tsis tu ncua;
• tsim nyog los tswj cov qauv metallographic ntawm cov khoom, sib nqus permeability;
• Nyeem xyuas cov khoom siv rau qhov hardness.

Rau kev ua haujlwm ntxiv, cov hlau no feem ntau yog tsim los ntawm daim ntawv. Lawv feem ntau txawv ntawm ib leeg hauv daim ntawv ntev thiab tuab.

Raws li kev tshuaj xyuas, lawv zoo heev. Qee cov neeg siv tau sau tseg tias txawm tias tom qab siv thawj zaug, nws tau pom tseeb tias cov cuab yeej ua los ntawm cov hlau nrog lub zog siab. Qee tus neeg hais tias rab riam no zoo tag nrho. Nws tau sau tseg tias tus kov ntawm cov cuab yeej no yog qhov yooj yim heev, tab sis nws zoo li zoo nkauj heev. Yuav kom ua tiav cov nyhuv no, stabilized ntoo nrog ntxiv ntawm birch bark yog siv. Ua tsaug rau cov xwm txheej no, nws tuaj yeem siv rab riam txawm tias nyob hauv huab cua hnyav thiab tsis muaj hnab looj tes. Cov hniav lawv tus kheej ntawm cov riam no yog ua nyob rau hauv ib tug classic style thiab taw tes rau qhov kawg. Nws nyob hauv qab thiab nrog txoj kab nqes me ntsis kom nws yooj yim dua rau siv.
