Khoom Description
ASTM A519 Seamless Automotive Hlau Tube
Vim li cas ASTM A519 cov kav dej muaj qhov zoo dua hauv kev lag luam tsheb?
1. Cov khoom siv cav yog cov khoom tseem ceeb ntawm lub tsheb, yog li nws yog ib qho tseem ceeb heev uas yuav tau xaiv cov yeeb nkab siab - zoo. Yog tias muaj cov dej xau hauv cov roj txhaj tshuaj, nws yuav ua rau muaj teeb meem ntau yam, thiab cov yam ntxwv tsis sib haum ntawm ASTM A519 cov kav dej tuaj yeem daws qhov teeb meem no zoo.
2. Shock absorbers yog cov khoom tseem ceeb uas txuas cov log rau hauv lub cev, ua kom lub zog du ntawm kev tsav tsheb. Cov kav dej zoo li no yuav tsum tiv taus qhov siab loj, thiab 4140 qib alloy hlau ntawm ASTM A519 cov kav dej muaj zog tensile siab, uas yog txaus los tiv thaiv lub siab loj.
3. Cov ncej tsav yog lub hauv paus tseem ceeb hauv lub zog xa hluav taws xob ntawm lub tsheb, thiab qhov tseeb ntawm cov yeeb nkab loj yog qhov siab heev. ASTM A519 cov kav dej tuaj yeem ua kom paub meej qhov sib npaug thiab qhov nyuaj uas xav tau, thiab tuaj yeem xa hluav taws xob zoo.

Cov qhab nia xaiv tau
Thaum ASTM A519 muaj ntau yam ntawm cov qhab nia tsim nyog rau kev siv tsheb, qee qib lwm yam uas yuav raug txiav txim siab suav nrog:
SAE J524 rau qis- carbon steel tubing
DIN 2391 rau precision steel raj
JIS G3445 rau carbon steel raj rau lub tshuab ua haujlwm
Ntim
Thaum cov kav dej tau dhau tag nrho cov kev tshuaj xyuas thiab kev sim, lawv npaj txhij rau ntim. Lawv feem ntau yog ntim rau hauv bales qhwv hauv yas. Cov kav dej tuaj yeem muab ntim thiab npaj rau kev xa khoom raws li cov neeg siv khoom xav tau, kom ntseeg tau tias cov kav dej muaj kev tiv thaiv thaum lub sijhawm thauj mus los thiab tiv thaiv qhov chaw puas.
