Ntau tus neeg, txawm tias tsis ncaj ncees lawm tsis cuam tshuam nrog kev lag luam hlau, zoo li yuav tau hnov txog cov khoom xws li stainless hlau. Tab sis vim qhov tseeb tias tsis yog peb txhua tus muaj txawm tias muaj kev paub dhau los hauv kev ua hlau hlau, stainless hlau qee zaum tau txais txiaj ntsig zoo, tab sis deb ntawm qhov tseeb, cov khoom.

Rau lub hom phiaj ntawm kev kawm, kab lus no tau sau, piav qhia txog ib qho ntawm cov hlau uas zoo siab hu ua "stainless steel". Ntawm cov txheej txheem yog steel 30x13, yam ntxwv, daim ntawv thov thiab ob peb yam tseem ceeb uas koj yuav tsum tau them sai sai rau.

Destination

Thawj qhov yuav tsum pib yog siv cov hlau 30 x 13, cov yam ntxwv uas yuav piav qhia tom qab. Tom qab tag nrho, paub qhov nws yog npaj rau, nws yuav yooj yim rau koj to taub txhua yam uas yuav tau tham hauv qab no.

Yog li, steel 30 x 13 yog corrosion-resistant, kub-resistant, high-alloy steel. Feem ntau, qhov chaw ua haujlwm nyob rau hauv ib puag ncig kev kub ntxhov yog tsim los ntawm nws, txawm li cas los xij, cov cuab yeej hauv tsev kuj tuaj yeem ua los ntawm cov hlau 30x13, cov yam ntxwv zoo.tso.

Ntawm no yog cov npe me me uas tuaj yeem ua los ntawm nws:

• caij nplooj ntoos hlav rau ntau lub hom phiaj;
• compressor qhov chaw;
• carburetor koob;
• ntsuas ntsuas;
• txhua hnub siv cov cuab yeej uas qhov kev tiv thaiv corrosion tseem ceeb;
• surgical instrument.

Txawm li cas los xij, ntawm qhov ntsuas kev lag luam, 30 x 13 kuj tseem pom nyob rau hauv daim ntawv ntawm cov ntawv txheeb, hlau, pas nrig, fittings thiab ntau yam khoom siv metallurgical dov.

Steel 30x13 - GOST

Tam sim no koj tuaj yeem txav mus rau qhov ze dua. Rau ntau tus, nws tsis yog qhov zais cia tias hlau yog qhov tseem ceeb ntawm cov hlau thiab carbon. Txawm li cas los xij, hom "huv" steel no tsis ua raws li cov kev cai uas yuav tsum tau ua rau nws (GOST 1133-71, 18143-72, thiab lwm yam). Txhawm rau txhim kho qhov teeb meem no, ntxiv impurities nyob rau hauv daim ntawv ntawm ntau yam tshuaj ntsiab lus yog nkag mus rau hauv nws muaj pes tsawg leeg, uas ntxiv txhim kho qhov zoo ntawm cov resulting alloy thiab endow nws nrog ib co khoom.

Rau cov hlau 30 x 13, cov ntsiab lus ntawm impurities yog raws li hauv qab no:

• 0.3% carbon;
• 13% chromium;
• 0.8% silicon;
• 0.8% manganese;
• 0.2% titanium;
• 0.3% tooj;
• 0, 6% npib tsib xee;
• 0.025% sulfur;
• 0.03% phosphorus.

Rau ib tus neeg tsis paub txog cov yam ntxwv ntawm cov khoom siv alloying, cov npe no zoo li yuav nkag tsis tau. Tab sis nyob rau hauv cov ntaub ntawv no, lub ntsiab impurities uas txiav txim siab cov yam ntxwv ntawm steel 30 x 13 yog carbon, uasvim nws cov ntsiab lus tsis tshua muaj nyob rau hauv tag nrho cov muaj pes tsawg leeg, nws ua rau steel harder, tab sis tsis txo nws elasticity, thiab chromium, uas ua rau muaj zog tiv thaiv corrosion. Silicon thiab manganese nyob rau hauv muaj pes tsawg leeg ua raws li kev txhawb nqa ncej, raws li lawv cov ntsiab lus txhim kho lub zuag qhia tag nrho hnav tsis kam thiab lub zog ntawm alloy.

Analogues

Steels nrog zoo tib yam lossis zoo sib xws yog tsis tshua muaj nyob rau hauv metallurgy. Feem ntau tib qib ntawm cov hlau tuaj yeem muaj ntau lub npe. Qhov no feem ntau piav qhia los ntawm qhov tseeb tias ntau lub tebchaws muaj cov npe sib txawv rau cov hlau thiab cov hlau. Yog li, analogue steels, sib npaug ntawm lawv cov yam ntxwv rau steel 30x13, dais cov npe hauv qab no:

• hauv Asmeskas - 420 lossis 420F;
• hauv Nyiv - SUS420J2;
• hauv Europe - 1, 4028 lossis X30Cr13;
• hauv Suav teb - 3Cr13.

Yog li, steel 30 x 13 kuj muaj nyob rau hauv kev lag luam txawv teb chaws. Thiab qhov no yog pov thawj tseeb tias cov hlau zoo li no tam sim no xav tau ntau.
