What is the difference between Q235B welding with H08mnA and H08A submerged arc welding wire? Which match is better? Ask professional personage to analyse for me
The manganese content of H08MnA is high, and the agglomerated flux is usually SJ101,The agglomerated flux of H08A is usually SJ301.That is to say, in order to achieve the Mn content in the weld, or add Mn (such as H08MnA) in the welding wire, or add SJ301 from the welding flux. The effect is the same.
H08mnA manganese content is higher, better performance. It is good for deoxidation and alloying of weldsHowever, the difference between the two is not big, the key depends on what you use welding flux to match
Nothing different.Better with H08A. It does not contain Mn
H08A wire welding is used to match Q345B steel welding with H08mnA welding wire. Therefore, the use of H08mnA wire, high prices.
