Q345E otentha adagulung'undisa zitsulo pepala

Q345 steel ndi Chinese GB yokhazikika ya Low Alloy High Strength Structural Steel, kachulukidwe kazinthu ndi 7.85 g/cm3, kulimba kwa 470-630 Mpa, ndipo mphamvu yotulutsa ndi 345 MPa, ili ndi katundu wabwinoko kuposa Q235. Malinga ndi GB/T 1591 – 2008, zinthu za Q345 zili ndi magiredi 5 abwino: Q345A, Q345B, Q345C, Q345D ndi Q345E.

Q345 chitsulo ali weldability wabwino, ozizira & otentha workability ndi kukana dzimbiri. Amagwiritsidwa ntchito kwambiri m'milatho, zombo, ma boilers, zotengera zokakamiza, akasinja osungira mafuta, makina onyamulira ndi zida zina zomata kwambiri.

Mechnical katundu wa Q345E otsika aloyi structural zitsulo:

Makulidwe (mm)
Q345E	≤16	> 16 ≤ 35	> 35 ≤ 50	> 50
Mphamvu zokolola (≥Mpa)	345	325	295	275
Tensile mphamvu (Mpa)	470-630

Chemical zikuchokera Q345E otsika aloyi structural zitsulo (Kutentha Analysis Max%)

♦ Mayeso a Ultrasonic pansi pa GB/T2970,JB4730,EN 10160,ASTM A435,A577,A578

FAQ
Q: Kodi nthawi yanu yobweretsera imakhala yayitali bwanji?
A: Nthawi zambiri ndi masiku 5-10 ngati katundu ali katundu. kapena ndi masiku 15-20 ngati katunduyo palibe, ndi molingana ndi kuchuluka kwake.

Q: Kodi mumapereka zitsanzo? ndi zaulere kapena zowonjezera?
A: Inde, tikhoza kupereka chitsanzo kwaulere koma osalipira mtengo wa katundu.
