hardness of BP300 steel, 45Mn2 steel is a kind of alloy structural steel. 45Mn2 steel is made of high-quality carbon structural steel with proper addition of manganese. 45Mn2 steel belongs to the medium carbon quenched and tempered steel in alloy structural steel. The parts made with 45Mn2 steel can obtain high strength and good toughness after quenching and tempering at high temperature. That is to say, 45Mn2 steel has good comprehensive mechanical properties and is often used to manufacture shafts, connecting rods, fasteners which bear large loads.

Q420C steel belongs to low alloy high strength steel. Q420 is named as the steel with yield strength of 420MPa, C means the impact temperature is 0 ℃, and Q is the abbreviation of yield strength. Chemical composition of Q420C steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420C steel are: yield strength ≥ 340 Mpa, tensile strength 500-680 Mpa, elongation after fracture ≥ 18%, impact energy 34J. hardness of BP300 steel, Q420C steel has good mechanical properties and weldability, good cold and hot workability.

hardness of BP300 steel, Q345 steel has good comprehensive mechanical properties. Q345 steel also has acceptable low temperature performance, good plasticity and weldability. Q345 steel 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. Q345 steel can be used in hot rolling or normalizing state, and can be used in various structures in cold regions below - 40 ℃.
