Q345Hd Steel Phaj Ntau Lawm thiab tej Txheej Txheem Txaus
Cov Txheej Txheem Ntau Lawm:
Koom haum siv cov tshuaj ntsuam → kev kuaj xyuas kub ntxiv
Tej txheej txheem txiav:
After the performance indicators of the Q345HD steel plate meet the requirements in the factory inspection, cutting processing is carried out according to the cutting technology. It can be cut and processed based on drawings. Generally, when the steel plate thickness is ≤20 mm, CNC plasma cutting or CNC laser cutting is preferred. If the steel plate thickness is >30 hli, CNC nplaim taws txiav yog feem ntau raug xaiv los tswj kev txiav kev txiav txim siab thiab lub sijhawm.
