Q345E kub dov steel ntawv qhia

Q345 steel yog Suav GB tus qauv Tsawg Alloy High Strength Structural Steel, cov khoom ntom ntom yog 7.85 g / cm3, tensile zog yog 470-630 Mpa, thiab yield zog yog 345 MPa, nws muaj zog dua Q235. Raws li GB/T 1591 – 2008, Q345 cov khoom muaj 5 qib zoo: Q345A, Q345B, Q345C, Q345D thiab Q345E.

Q345 steel muaj zoo weldability, txias & kub workability thiab corrosion kuj. Dav siv nyob rau hauv choj, nkoj, boilers, siab hlab ntsha, roj av cia tso tsheb hlau luam, nqa thauj machinery thiab lwm yam high-load welded structural qhov chaw.

FAQ
Q: Koj lub sijhawm xa khoom ntev npaum li cas?
A: Feem ntau nws yog 5-10 hnub yog tias cov khoom muaj nyob hauv Tshuag. los yog nws yog 15-20 hnub yog tias cov khoom tsis nyob hauv Tshuag, nws yog raws li kom muaj nuj nqis.

Q: Koj puas muab cov qauv? puas yog dawb los yog ntxiv?
A: Yog, peb tuaj yeem muab cov qauv dawb tab sis tsis them tus nqi thauj khoom.
