Since it was established in 2000. Based on the domestic rich a516 grade 70 thermal conductivity product resources and the great steel demand of the international market, our a516 grade 70 thermal conductivity service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products
Q690D steel belongs to high-strength welded structural steel. Among them, Q represents the yield strength, 690 represents the yield strength value, and D represents the grade of the steel plate. The quality grades of common Q690 series steel are A, B, C, D, E. The impact of grade D steel plate is -20°C. Q690D steel can be called a low temperature resistant high strength steel with a yield strength of 690Mpa.
The difference between Q195 steel and 20# steel: a516 grade 70 thermal conductivity, 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.
Generally speaking, rolled plates are easier to handle in a high temperature environment, and the heat treatment of a516 grade 70 thermal conductivity, rolled plates is also very common. Hot rolling can not only greatly reduce energy consumption and save costs, but also improve the processing performance of metals and alloys, that is, the coarse grains in the as-cast state are broken, the cracks are healed significantly, and the processing performance of the alloy is improved.
