The shipping department of the company arranges shipping booking for customers' goods in advance, and makes good matching with inland transportation. Effectively manage and follow up the customer's shipping schedule and give feedback to customers in time. At the same time, the shipping department has a keen insight into the shipping market in different periods to reduce the transportation cost for the company and customers.

The company operates Henan metallurgical rolling iron and steel factory all year round, providing steel products for various industries such as ow alloy high strength series, boiler and pressure vessel steel plate, power station engineering steel plate series, S460ML EN 10025-4 bridge structure steel plate, corrosion resistant steel plate, composite steel plate, high-rise building structure, die steel plate series, steel plate series for shipbuilding and offshore platforms, pipeline steel plate, alloy structure and other steel plates.

Chemical composition differences between the S460ML EN 10025-4, 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。

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized S460ML EN 10025-4 are higher than that of annealed S460ML EN 10025-4, but the elimination of internal stress is not as good as annealing. The normalizing operation of S460ML EN 10025-4 is simple, the cost is low, the productivity is high, and it is widely used in actual production.

Our company regularly visits customers, consults and follows up the after-sales service, and directly solves problems for customers. In the use of our steel materials, whether quality problems or not, the after-sales will help solve the problem as soon as possible. We promise free life-long replacement for any product quality problems. The sound after-sales service system make you free from worries.

The formula of enterprise success is: success = strategy × organizational capability, that is, having the right direction and strong organizational capability. The core competence of an enterprise depends on three pillars: first, talents (talent echelon); second, core values of enterprise culture; third, organizational governance model. If the enterprise is a tree, then the core values of talents, corporate culture and organizational governance mode are just like the root of the tree. With them, the enterprise will flourish and grow forever.
