The temperature of A514 Gr Q steel material heat treatment

A514 Gr Q steel material, No. 55 steel delivery status: delivered in the state of no heat treatment or heat treatment (annealing, normalizing or high temperature tempering). If it is required to be delivered under heat treatment, it should be indicated in the contract. If it is not specified, No. 55 steel shall be delivered without heat treatment. Specification for heat treatment of No. 55 steel: normalizing, 820℃; quenching, 820℃; tempering, 600℃. Metallographic structure: sorbite.

10 to 20mm thick A514 Gr Q steel material product: 10*2200*7200, 10*2200*8000, 12*2000*11850, 12.5*2900*11000, 12.9*2987*10384, 13.6*2940*11455, 14*2000*10000, 14*2000*11181, 14*2000*13500, 14*2070*9060, 14*2200*10030, 15*2200*10270, 15*2500*10000, 15*2992*10185, 16*1500*9340, 16*1800*6000, 16*2000*10713, 16*2120*6080, 16*2200*10000, 16*2230*7650, 18.5*2320*6600, 20*1400*11400, 20*2100*7000.

In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the A514 Gr Q steel material steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.

A type of material that uses a large amount of A514 Gr Q steel material steel plates is divided into ordinary low-carbon steel plates and special steel plates, including low-alloy high-strength steels and corrosion-resistant and heat-resistant multi-layer steel plates. Ordinary low-carbon steel plates are divided into two types: cold-rolled and hot-rolled. Cold-rolled A514 Gr Q steel material steel plates have good surface quality and accurate thickness dimensions. They are mostly used to make car bodies. Hot-rolled plates are mostly used to make car frames and the like.
