Q345E u'amea u'amea vevela

Q345 u'amea o se Saina GB tulaga Low Alloy High Malosi Structural Steel, density mea e 7.85 g /cm3, tensile malosi o le 470-630 Mpa, ma maua le malosi o le 345 MPa, e sili atu meatotino nai lo Q235. E tusa ai ma GB/T 1591 – 2008, Q345 meafaitino e 5 tulaga lelei: Q345A, Q345B, Q345C, Q345D ma Q345E.

Q345 sila ua lelei weldability, malulu & vevela workability ma corrosion tetee. Fa'aaoga lautele i alalaupapa, va'a, fa'afu, va'a mamafa, tane fa'aputu suau'u, masini fela'uaiga si'i ma isi vaega fa'apipi'i fa'apipi'i maualuga.
