Hlau xeb: theem pib hom, npav thiab siv cov

peb yuav tsum engineer Harry Brearli advent ntawm stainless hlau. Ntxiv ib tug hlau tshuaj caij hu ua chromium, nws sim mus cuag kev nce ntawm cov melting kub. Qhov no yog yuav tsum tau txhim kho cov kev kawm ntawv ntawm artillery tej kas tham. Thaum lub sij hawm no thwmsim nws pom hais tias lub resulting hlau muaj sib txawv raws li muab piv nrog lwm leej lwm tus. Lawv muaj xws li nyob rau hauv cov tshuaj kuj. Qhov no tshwm sim vim tus tsim rau ntawm qhov chaw ntawm zaj duab xis ntawm chromium oxide.

Stainless hlau tshawb fawb pib nyob rau hauv 1871, thiab cov thawj patent tau sau npe xwb nyob rau hauv 1913. Cov niaj hnub sib npaug ntawm stainless steel uas muaj raws li tag nrho cov uas yuav tsum tau kom koj muaj zog thiab tshuaj zog, twb tau nyob rau hauv 1924, zaum ntawm Hartfield tsev neeg.

Lub tswv yim tseem ceeb ntawm lub stainless steel

Cov ntaub ntawv ua tim khawv los yog lwm yam corrosion-resistant steel muaj cov nram qab cim: "qib steel 08H18N10". Qhov no txhais tau tias cov ntsiab lus nyob rau ntawd cov nram qab no hais:

• carbon - tsis ntau tshaj li 0.8%;
• chromium - 18%;
• npib tsib xee - 10%.

Qhov no yooj yim tshuaj hais, tab sis kuj tam sim no nyob rau hauv lub hlau thiab lwm yam impurities, cov feem pua ntsiab lus yog tsis ntau tshaj li 1%.

Lub ntsiab stainless steel khoom

Ua los ntawm stainless steel high-quality khoom xws li:

• stainless steel hlau;
• steel ntawv ;
• kav ntawm txawv phab ntsa thicknesses thiab puab inch;
• zoo li tus khoom.

Tsis tas li ntawd muaj ntau yam tsev neeg riam thiab khoom noj khoom haus processors ntshav yog ua los ntawm no xyov khoom.

Tus Hlau Stainless Hlau

Zoo li tej lwm yam khoom steel hlau ua raws li qhov tam sim no Lavxias teb sab qauv.

Nws regulates zus tau tej cov xws teeb meem raws li stainless hlau, GOST 18143-72. Raws li daim ntawv no, nws muaj ib tug tuab ntawm los ntawm 0.3 mus rau 6 lub millimeters.

Xws li ib tug hlau tej zaum yuav siv tau raws li ib tug zaum kawg khoom thiab yuav ntxiv ua los ntawm molding. Ces tawm ntawm nws, thov hu rau:

• saw mus nrog sib txawv loj,
• daim phiaj nrog ib tug txawv kauj ruam ntawm lub cell,
• caij nplooj ntoos hlav.

Cross-seem ntawm ib tug hlau, feem ntau yog puag ncig, tab sis koj muaj peev xwm kuj tau raws li dawb los yog square views. Cylindrical seem yog heev pab tau thaum uas siv cov ntaub ntawv nyob rau hauv tus txheej txheem ntawm vuam ntawm tib stainless hlau.

Steel hlau muaj cov nram qab ntsiab zoo:

• theem ntawm xeb kuj mus ya raws, txhoj puab heev muaj tej kev kawm thiab hws;
• hlau uas muaj cov ntsiab lus ntawm molybdenum, chromium, npib tsib xee, tooj liab, pob zeb ntais, vanadium muaj high tshav kub tsis kam, kev cia siab thiab durability.

Kev siv cov stainless steel hlau

Vim ntev lub neej, ua hauj acidic thiab alkaline xov xwm, hlau ntawm stainless steel tau lug siv nyob rau hauv ob txoj kev:

• knitting nyob rau hauv lub ropes;
• vuam;
• Knitted mesh lim.

Hlau xeb, tus nqi ntawm uas nws txawv ntawm 120 rau 350 rubles ib kilogram, nyob ntawm seb lub thickness thiab cov yam ntxwv, tau txais ntau siv nyob rau hauv lag luam xws li:

• engineering;
• hluav taws xob;
• roj;
• tshuaj;
• khoom noj khoom haus.

vuam hlau

Dav tshuaj lag luam loj hlob yuav tsum tau cov creation ntawm metallurgical hlau muaj peev xwm tswj siab txhua yam khoom nyob rau hauv corrosive tej kev kawm. Nyob rau hauv tas li ntawd mus tsis kam mus rau ntau yam tshuaj ntsiab yuav tsum tau nyob rau hauv ib co industries thiab txawm zog nyob rau hauv uas lub hlau mas tsis tshua muaj neeg siab kub. Stainless hlau daws muaj ntau yam ntawm cov kev pab raws qib. Ntxiv mus, cov kev siv nyob rau hauv lub lag luam ua noj yuav tsis yog ib tug txawv cov ntaub ntawv uas.

Cov niaj hnub theem ntawm kev ntawm hlau khoom enables mus tsim txoj khoom, tab sis tag nrho cov no yuav tsis ua li cas tsis welded pob qij txha. Stainless hlau hlau yog siv rau welding cov khoom nyob rau hauv txoj kev sibtham uas raug txhoj puab heev tej kev kawm.

Lub ntsiab kom zoo dua muaj los ntawm stainless vuam hlau, yog hais tias thaum lub sij hawm siv cov welded leeg tshuam ntshiab, uas tsis muaj teeb meem slags thiab inclusions parasitics. Los ntawm kev siv stainless steel khoom nws tus kheej leeg yog tsis raug oxidation. Them nyiaj rau cov zoo yog hais tias lub vuam txoj kev nyob rau hauv cov ntaub ntawv no yog heev nyuab, thiab cov khoom siv - txoj kev.

Stainless hlau hlau yog tsuas yog siv nyob rau hauv tsis siv neeg welding. Nws tau txais kev pab ib qho automatic feeder, vim nws yog qhia.

Lub arc tsam nkag mus rau ib tug tiv thaiv cov roj uas displaces lub oxidizers los ntawm no muaj ib tug ua tiav leeg prosekanie thiab kev twb kev txuas ntawm tag nrho cov Cheebtsam.

Lub Vuam hlau yog lub qhov txhab nyob rau hauv ib tug hlau nruas mus rau ib tug tas mus li ntev ntawm 50 meters. Qhov nruab nrab txoj kab uas hla ntawm lub nruas yog 50 millimeters. Feed nrog ib tug ntxaiv ua teb tshwm sim hlau biasing lub ob coils. Nyob rau hauv nruab nrab-txiav oblique grooves, uas muaj ib tug paub tseeb tuav ib tug hlau thiab pub nws mus rau lub vuam rab phom. Ua ntej nws stainless hlau qhov txhab kom huv si ntxuav ntawm av thiab txawv teb chaws muaj teeb meem.

Npav ntawm lub vuam hlau

Hlau yog manufactured los ntawm tus mob khaub thuas dov thiab kub ua hauj lwm. Nws muaj ob hom ntawm precision - li qub thiab siab. Nyob rau hauv lub caij nyoog kawg no cov ntaub ntawv, tom qab labeling nyob rau hauv pab pawg, tsab ntawv P.

Hlau xeb muaj ob lub ntsiab cim - domestic thiab txawv teb chaws.

Lavxias teb sab labeling muaj ib tug alphanumeric saib - 10X17H13M2T. Tus tom ntej kev txiav txim ntawm cov tsiaj ntawv thiab ua zauv txhais li cas nws nrog cov qauv thiab tshuaj muaj pes tsawg leeg. Nuj nqis txiav txim feem pua ntawm ib tug tej lub caij, thiab tsab ntawv - lub caij nws tus kheej. Qhov saum toj no tsiaj ntawv yog txhais raws li nram no:

• 0.1% carbon;
• chromium - 17%;
• npib tsib xee - 13%
• manganese - 2%
• tsab ntawv T ntawd hais tias cov hlau yog ua los ntawm tshav kub kev kho mob.

Cov nyob sab Europe tus qauv yog heev thiab twb tsis muaj niaj hnub labeling ntawm cov qauv. Txhua Chaw tsim tshuaj paus ntawm steel patented nws muaj pes tsawg leeg.
