Raws li koj tuaj yeem pom los ntawm txhua hom hlau thiab hlau alloy, steel 10 yog cov khoom siv hluav taws xob qis. Qhov no yog li cas nws yog hu ua nyob rau hauv tag nrho cov ntaub ntawv kev txawj ntse, tab sis tej zaum nws lub npe yog abbreviated nyob rau hauv ib tug txawv txoj kev, namely ST 10. Tab sis ib txoj kev los yog lwm yam, nws lub npe - tag nrho thiab abbreviated - qhia peb ntau.

Nws tsim nyog pib nrog qhov tseeb tias tus lej 10 tau qhia nyob rau hauv lub npe ntawm qib steel vim yog vim li cas. Tus neeg twg uas tsawg kawg yog luv luv nrog lub Soviet GOST system, nws tam sim ntawd paub meej tias tus naj npawb 10 nyob rau hauv cov ntaub ntawv no qhia cov feem pua ntawm lub ntsiab alloying ntsiab nyob rau hauv cov hlau muaj pes tsawg leeg. Raws li tau pom meej los ntawm cov lus piav qhia, qhov no yog carbon (C).

Tseem los ntawm lub npe peb paub lub hom phiaj tseem ceeb ntawm lub npe tshwj xeeb no. Cov qauv hlau yog cov hlau uas ncaj qha rau kev tsim khoom ntawm ntau hom qauv, nrog rau ntau yam txheej txheem thiab qhov chaw rau lawv.

Steel 10 - GOST

Ntawm txhua qhov sib txawv ntawm cov alloys sib txawv, qib 10 steel tsis sawv tawm rau nws ntau yam.additives nyob rau hauv muaj pes tsawg leeg. Txawm li cas los xij, txawm tias cov hlau yooj yim no muaj lawv, uas yog vim li cas nws tsim nyog paub koj tus kheej nrog lawv. Yog li, steel 10 thiab nws cov ligature muaj pes tsawg leeg raws li feem pua:

• carbon - 0.07-0.14;
• chrome - mus txog 0, 15;
• silicon - 0.17-0.37;
• nickel - mus txog 0.25;
• phosphorus - txog 0,035;
• manganese - 0.35-0.65;
• tooj liab - mus txog 0.25;
• arsenic - mus txog 0.08;
• sulfur – mus txog 0, 04.

Steel 10 yam ntxwv

Lawv yog dab tsi? Raws li qhov muaj pes tsawg leeg, nws tau pom tseeb tias steel 10 (piv nrog ntau lwm cov alloys) tsis txawv ntawm qhov tshwj xeeb hardness thiab lub zog. Qhov no muaj tseeb, tab sis rau kev lag luam steel qhov no tsis yog ib qho kev rho tawm. Ntawm qhov tsis sib xws, rau cov qauv hlau raug rau cov khoom siv siab, ductility yuav yog qhov zoo tshaj plaws, uas yog vim li cas cov ntsiab lus alloying muaj cov additives uas txo qis qhov kawg hardness me ntsis, thiab vim li ntawd, lub brittleness ntawm lub resulting alloy.

Ntawm lwm yam, xws li kev dag ntxias muaj ntau qhov txiaj ntsig zoo ntxiv ntawm cov hlau. Piv txwv li, steel 10 tsis yog tag nrho raug rau temper brittleness. Qhov no txhais tau hais tias txawm tias thaum cov hlau siv los ntawm qhov kub siab, nws cov yam ntxwv muaj zog, uas yog, qhov cuam tshuam lub zog, yuav nyob twj ywm tsis hloov lossis nce me ntsis. Nws yog qhov tseeb vim tias cov cuab yeej no uas nws thiab cov hlau zoo sib xws feem ntau siv rau, piv txwv li, boiler piping, qhov twg muaj qhov kub thiab txias ib puag ncig nrog kev hwm rau steel.

Cov cuab yeej zoo tom ntej ntawm qib steel no- tsis kam mus rau sab hauv tsis xws luag, xws li pab yaj. Vim lub homogeneous qauv, cov khoom kawg, txawm tias nyob rau hauv lub siab ntawm loads siab, yuav tsis nquag mus splitting, chipping thiab cracking.

Kawg ntawm daim ntawv, tab sis tsis tsawg, yog qhov weldability ntawm qib 10 steel. Rau cov txheej txheem alloy, cov cuab yeej no tsis muaj qhov tseem ceeb tshaj li nws lub zog, vim tias feem ntau cov qauv hlau tau sib sau ua ke ntawm cov sib koom ua ke, uas txhais tau hais tias lub zog ntawm kev sib koom ua ke yuav tsum siab tshaj plaws thiab kev sib txuas ntawm cov hlau ua lub luag haujlwm tseem ceeb hauv qhov no.

Analogues

Nws tsis yog qhov xav tsis thoob tias qhov yooj yim "daim ntawv qhia" hlau tsis yog ib qho ntawm nws hom. Ntxiv rau qib 10 Soviet, cov alloys no tau siv dav hauv lwm lub tebchaws, tab sis nyob rau hauv cov npe sib txawv. Piv txwv li:

• Tebchaws Meskas - M1010, M1012, S 1010;
• Europe - 1, 1121, 2C10, C10E;
• Japan - S10C, SASM1, S12C.

Raws li koj tuaj yeem pom, steel 10 muaj ntau qhov sib piv thoob ntiaj teb.

Daim ntawv thov

Yog li cov hlau no siv nyob qhov twg? Qhov tseeb, yog tias peb tsis suav nrog ntau cov analogues thiab hloov pauv rau steel 10, tom qab ntawd nws yog siv los ntawm txhua lub lag luam hauv nws cov kev hloov pauv ntau yam, txawm tias nws yog daim ntawv, sawb, daim kab xev, tuav ntawm ntau yam calibers, square thiab hexagon ntawm ntau ntu, nrog rau cov kab, kab teeb, xaim thiab cov kav dej sib txawv.
