ASTM 4140 Kub Rolled Forged Alloy Steel Round Bars

Product Description:

Round steel yog hais txog cov khoom ntev steel nrog cov ntu ntu.Nws specification yog qhia nyob rau hauv txoj kab uas hla (mm).Piv txwv li, "50mm" yog hais txog cov hlau puag ncig nrog txoj kab uas hla ntawm 50mm.

Kev faib tawm los ntawm txheej txheem:

Round steel yog muab faib ua kub dov, forging thiab txias kos duab.Qhov tshwj xeeb ntawm kub dov puag ncig steel yog 5.5-250mm.Ntawm lawv, 5.5-25mm me me puag ncig steel feem ntau yog muab rau hauv cov khoom ntawm cov kab ncaj nraim, feem ntau siv los ua kev txhawb zog, bolts thiab ntau yam khoom siv;Round steel loj dua 25 hli yog siv rau kev tsim tshuab, seamless steel tube billets, thiab lwm yam.

Classification los ntawm chemical muaj pes tsawg leeg:

Cov pa roj carbon steel tuaj yeem muab faib ua cov pa roj carbon tsawg, nruab nrab carbon steel thiab siab carbon steel raws li cov tshuaj muaj pes tsawg leeg (xws li cov ntsiab lus carbon).

Classification raws li steel zoo:

Raws li qhov zoo ntawm cov hlau, nws tuaj yeem muab faib ua cov pa roj carbon zoo tib yam thiab cov pa roj carbon zoo.

Qhov sib txawv ntawm puag ncig steel thiab lwm yam kev txhawb nqa:

1. Cov tsos mob txawv.Cov hlau puag ncig yog du thiab puag ncig, tsis muaj wrinkles los yog ribs, thiab nto ntawm lwm cov hlau tuav yog carved los yog ribbed, uas ua rau ib tug me me daim ntawv cog lus ntawm puag ncig steel thiab cov pob zeb, thaum lub sij hawm sib raug zoo ntawm lwm cov hlau tuav thiab cov pob zeb yog loj.

2. Cov muaj pes tsawg leeg yog txawv.Round steel (Qib I steel) belongs rau cov pa roj carbon tsawg zoo tib yam, thiab lwm cov hlau tuav feem ntau yog hlau alloy.

3. Lub zog ntawm round steel yog txawv.Lub zog ntawm cov hlau puag ncig yog qis, thaum lub zog ntawm lwm cov hlau yog siab.Ntawd yog, piv nrog rau lwm qhov kev txhawb nqa, cov hlau puag ncig nrog tib txoj kab uas hla tuaj yeem dais qhov nro, tab sis nws cov yas muaj zog dua li lwm cov khoom siv ntxiv.Ntawd yog, cov hlau puag ncig muaj ntau dua deformation ua ntej raug rub tawm, thaum lwm qhov kev txhawb nqa muaj ntau qhov me me deformation ua ntej rub tawm.

2.Koj lub sijhawm xa khoom ntev npaum li cas?

Raws li qhov kom muaj nuj nqis. Feem ntau nyob rau hauv 2-7 hnub yog nyob rau hauv Tshuag.Thiab 15-20 hnub yog tsis nyob rau hauv Tshuag.

3.Koj cov nqe lus them nqi yog dab tsi?

A: Los ntawm T / T 30% ua ntej, thiab 70% ua ntej xa khoom.

B: 100% L / C thaum pom.

C: Los ntawm T / T 30% ua ntej, thiab 70% L / C thaum pom.

4.Koj puas muab cov qauv?Puas yog dawb?

Yog lawm, peb muab cov qauv dawb tab sis tsis them tus nqi thauj khoom.

5.Yuav ua li cas yog tias tus neeg siv khoom tsis txaus siab?

Yog tias muaj teeb meem nrog cov khoom, peb ua lub luag haujlwm tag nrho.

Yog tias muaj teeb meem hauv kev thauj mus los, peb yuav pab koj daws nws.
