Difference between Q235 and Q345:
Q235 is ordinary carbon steel, 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 is a low alloy steel with good comprehensive mechanical
properties, low temperature performance, good plasticity and
weldability. It is used as structures, mechanical parts, building
structures and general metal structure components bearing dynamic
load 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.
