What is the difference between Q235a and Q235b?
- The biggest difference between the two is that Q235A steel does not undergo impact testing, while Q235B steel undergoes 20-degree impact testing.
- In addition, the sulfur content of Q235A steel is higher than that of Q235B, and the toughness of Q235B steel is better than that of Q235A steel.
Will Q235 steel rust?
Any steel will rust, some steels are easy to rust, and some steels are not easy to rust.Q235 steel itself is not corrosion-resistant, and it is easy to rust without surface treatment.The surface treatment of wanzhi steel for rust prevention is galvanizing.
What are the differences between Q235 steel and Q345 steel?
- One obvious difference between the two is the yield value. The yield value of Q235 steel is about 235MPa, and the yield value of Q345 steel is about 345MPa.
- In addition, Q235 is ordinary carbon steel, and Q345 is low alloy steel.It should also be noted that the chemical composition of Q235 steel and Q345 steel is different.
- The above differences determine the different prices of the two steels. The price of Q235 steel is lower than that of Q345 steel.
