Q345A Q345B Q345C Q345D Q345E H Steel profile

 

 

Q345 yog hom khoom siv hlau. Nws yog ib co hlau qis (c<0.2%), widely used in construction, bridges, vehicles, ships, pressure vessels, etc. Q stands for the yield strength of the material, followed by 345, which means the yield value of the material, in the range of 345 MPa. The yield value of the material is around 345 MPa, and will decrease with the increase of the thickness of the material.

 

Q345 qauv hlau txheem hlau raws li cov qhab nia tuaj yeem faib ua Q345A, Q345C, Q345S, Q345E. Lawv sawv cev, tsuas yog qhov cuam tshuam ntawm qhov kub yog txawv. Q345A qib steel nqaj, tsis yog ua qhov cuam tshuam; Q345B cov kauj ruam nqaj ntawm hlau, yog qhov cuam tshuam ntawm qhov kub ntawm 2 0 degrees; Q345C qib steel nqaj h, yog 0 degrees cuam tshuam; Q345d qhab-h Hom nqaj, yog -20 degrees cuam tshuam; Q345e Qeb H Zoo li cov nqaj, yog -40 degrees cuam tshuam. Ntawm kev cuam tshuam sib txawv, cov txiaj ntsig ntawm feem sib txawv.

 

Lub ntsiab sib xyaw ua ke ntawm Q345 steel caij sib piv thiab 16mn steel yog yeej zoo ib yam, qhov txawv yog nce ntxiv V, ti, NB trace alloying ntsiab. Ib qho me me ntawm V, Ti, NB alloying ntsiab yuav kho cov nplej, txhim kho cov khoom siv hluav taws xob nruj heev, cov khoom siv tshuab hluav taws xob zoo heev tau txhim kho.
