Difference between Q235 and Q345:
Q235 - metal structural parts, carburized or cyanide parts with low
core strength requirements, pull rods, connecting rods, hooks,
couplers, bolts, nuts, sleeves, shafts and weldments.
Q345 -- good comprehensive mechanical properties, low temperature
performance, good plasticity and weldability. It can be used as
structures, mechanical parts, building structures and general metal
structures bearing dynamic loads such as medium and low pressure
vessels, oil tanks, vehicles, cranes, mining machinery, power
stations and bridges. It can be used in hot rolling or normalizing
state. It can be used for various structures in cold areas below -
40 ℃.
If the structure is controlled by strength, Q345 can be considered;
if the structure is controlled by stiffness, Q235 can be
considered. Q345 is a little expensive, but it can save materials
because of its high strength. The specific selection can be
comprehensively compared from the above points.
