Muaj ib txwm muaj cov cuab yeej tsim nyog rau txoj haujlwm, thiab feem ntau tsis yog, nws xav tau cov hlau zoo los ua cov cuab yeej ntawd.A2 yog qib feem ntau ntawm steel bar siv los ua cov cuab yeej rau shaping hlau, ntoo, thiab lwm yam ntaub ntawv.A2 nruab nrab-carbon chromium alloy steel yog ib tus tswv cuab ntawm cov cuab yeej ua haujlwm txias ua haujlwm steel, tsim los ntawm American Iron and Steel Institute (AISI), uas suav nrog O1 qis-carbon steel, A2 steel thiab D2 high-carbon high-chromium steel.

Cov cuab yeej ua haujlwm txias steel yog qhov kev xaiv zoo rau cov khoom uas xav tau qhov sib npaug ntawm kev hnav tsis kam thiab toughness.Lawv kuj ua haujlwm zoo rau qhov chaw uas xav tau qhov tsawg kawg nkaus ntawm qhov shrinkage los yog distortion thaum lub sij hawm hardening txheej txheem.

Kev hnav tsis kam ntawm A2 steel yog nruab nrab ntawm O1 thiab D2 steel, thiab nws muaj cov khoom siv zoo thiab sib tsoo.A2 yog tawv dua li D2 steel, thiab muaj kev tswj qhov ntev zoo dua tom qab kev kho cua sov dua li O1 steel.

Hauv ib lo lus, A2 steel sawv cev qhov sib npaug zoo ntawm tus nqi thiab cov yam ntxwv ntawm lub cev, thiab feem ntau suav hais tias yog lub hom phiaj dav dav, universal steel.

Kev sib xyaw

A2 hlau yog cov feem ntau siv ntau yam ntawm Pawg A steels teev nyob rau hauv ASTM A682 tus qauv, uas yog xaiv "A" rau huab cua hardening.

Thaum cov txheej txheem kho cua sov, cov ntsiab lus nruab nrab ntawm cov pa roj carbon monoxide ntawm li 1% tso cai rau A2 steel los txhim kho tag nrho cov tawv nqaij los ntawm kev ua kom txias hauv cov huab cua tseem ceeb - uas tiv thaiv qhov sib txawv thiab tawg uas tuaj yeem tshwm sim los ntawm dej quenching.

Cov ntsiab lus chromium siab (5%) ntawm A2 hlau, nrog rau manganese thiab molybdenum, tso cai rau nws ua tiav tag nrho hardness ntawm 57-62 HRC nyob rau hauv tuab seem (4 ntiv tes inch) - muab nws zoo seem stability txawm rau qhov loj.

Daim ntawv thov

A2 steel bar muaj nyob rau hauv ntau hom, suav nrog square, puag ncig, thiab tiaj tus.Cov khoom siv ntau yam no tuaj yeem siv rau ntau yam cuab yeej uas yuav tsum tau hnav tsis kam, xws li cov hammers, riam, slitters, punches, cuab yeej tuav, thiab cov cuab yeej txiav ntoo.

Rau cov ntxig thiab cov hniav, A2 steel tiv thaiv chipping kom nws kav ntev dua, feem ntau ua rau nws xaiv kev lag luam ntau dua li cov pa roj carbon ntau D2 hom hlau.

Nws yog feem ntau siv rau blanking thiab sib sau xov cov menyuam tuag, stamping tuag, trimming tuag, txhaj pwm tuag, mandrels, pwm, thiab spindles.

Shanghai Histar Hlaumuab A2 cuab yeej steel bar hauv square, tiaj tus thiab puag ncig hauv ntau qhov ntau thiab tsawg.Tiv tauj peb rau ib nqe lus los yog mus saib peb lub vev xaib.
