The difference between low alloy high strength steel plate and carbon steel plate, A514 Gr Q structural steel material:(1) Strength difference between low alloy high strength steel plate and carbon steel plate:The strength of low alloy high strength steel plate is higher than that of carbon steel plate;(2) Hardness difference between low alloy high strength steel plate and carbon steel plate:The hardness of low alloy high strength steel plate is higher than that of carbon steel plate;(3) Usage difference between low alloy high strength steel plate and carbon steel plate:The application range of low alloy high strength steel plate is wider than that of carbon steel plate.
A514 Gr Q structural steel material, Q345B low alloy steel has outstanding characteristics, such as: First, Q345B low alloy steel has good toughness. It is easy to bend and stretch, not easy to break, and can be used for multiple processing. Second, A514 Gr Q structural steel material, Q345B low alloy steel is easy to weld and can be used for assembly. Third, Q345B low alloy steel has good strength, good compression resistance and long service life. Fourth, the weather resistance of Q345B low alloy steel is good, and the use is not affected whether it is winter or summer.
Vanadium mainly exists in the form of carbide in A514 Gr Q structural steel material and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.
What is the difference between Q345B steel and Q345A steel? A514 Gr Q structural steel material, Q345B steel and Q345A steel have slight difference in chemical composition: Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15; Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15. The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.
