It is very important for an enterprise to have a sound after-sales service system, which not only ensures the normal outflow and inflow of the company's products, but also improves the trust of the company's products in the hearts of customers. Our company has a special after-sales service team and good after-sales service reputation. In case of any problem in the use of our steel products A514 Gr Q steel material , whether quality problem or not, the after-sales service department will assist in solving the problem as soon as possible, and regularly consult and track the use of the steel products.

The production process of hot-rolled steel plate and cold-rolled steel plate is different. Hot rolled steel plate is rolled at high temperature, and cold rolled steel plate is rolled at normal temperature. Generally speaking, cold rolled steel plate has better strength and hot rolled steel plate has better ductility. The thickness of A514 Gr Q steel material cold rolling is generally smaller, and that of hot rolling can be larger. The surface quality, appearance and dimension accuracy of cold rolled steel plate are better than that of hot rolled steel plate.

The boiler steel plate has small strain aging sensitivity, especially in the corresponding working temperature range, a certain value of aging impact energy must be guaranteed;The boiler steel plate has low notch sensitivity, which can prevent steel from cracking in welding, opening, and local stress concentration areas;The A514 Gr Q steel material, boiler steel plate has good welding performance;The A514 Gr Q steel material, boiler steel plate has a good microstructure, white spots and cracks are not allowed.

Chemical composition differences between the A514 Gr Q steel material, Q345 steel grades (Q345A / Q345B / Q345C / Q345D / Q345E):Q345A steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.035，S≤0.035； Q345B steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.035，S≤0.035； Q345C steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.030，S≤0.030，Al≥0.015； Q345D steel：C≤0.18，Mn ≤1.70，Si≤0.50，P≤0.030，S≤0.025，Al≥0.015； Q345E steel：C≤0.18，Mn ≤1.70，Si≤0.50，P≤0.025，S≤0.020，Al≥0.015； All the Q345 steel grades contain Nb≤0.07，V≤0.15，Ti≤0.20，Cr≤0.30，Ni≤0.012，Mo≤0.10。

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
