Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.
The difference between Q195 steel and 20# steel: astm a242 type 1 corten steel H beam, Q195 steel is ordinary carbon structural steel, in which alloy elements are not specially added, and it is mainly used for construction and engineering structures. Q195 steel has low carbon and manganese content, low strength, good plasticity, high toughness, and good process performance and weldability. 20# steel is high-quality carbon structural steel. Alloy elements are not specially added to 20# steel, and it is mainly used in the manufacture of machine structures, and the amount of use is particularly large. 20# steel has higher strength than Q195 steel, good weldability, no temper brittleness, and its workability can be improved by water quenching.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the astm a242 type 1 corten steel H beam metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between astm a242 type 1 corten steel H beam strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
LSAW Pipe to Peru. In the beginning of 2014, Peru government released an international tender for one of the hydroelectric power plant. Finally they chose us as the contractor, we purchased the steel plate and then fabricate the astm a242 type 1 corten steel H beam steel plate into steel pipe, and then make the corrosion protect on the surface, we also supply the fitting with our steel plate, the total value of this order is about 2 million USD.
