HCT780C
HCT780C steel is a high-strength hot-dip galvanized composite sheet, and its execution standard is the German standard DIN EN 10346. The specific chemical composition range of HCT780C steel is as follows: carbon (C) ≤0.22%, silicon (Si) ≤0.60%, manganese (Mn) ≤2.00%, phosphorus (P) ≤0.085%, sulfur (S) ≤0.015%, aluminum (Al) ≤0.015%, chromium (Cr) ≤0.015%, molybdenum (Mo) ≤0.015%, copper (Cu) ≤0.50%, titanium (Ti) ≤0.165%.
Description
Product Application
HCT780C steel is a high-strength hot-dip galvanized composite sheet, and its execution standard is the German standard DIN EN 10346. The specific chemical composition range of HCT780C steel is as follows: carbon (C) ≤0.22%, silicon (Si) ≤0.60%, manganese (Mn) ≤2.00%, phosphorus (P) ≤0.085%, sulfur (S) ≤0.015%, aluminum (Al) ≤0.015%, chromium (Cr) ≤0.015%, molybdenum (Mo) ≤0.015%, copper (Cu) ≤0.50%, titanium (Ti) ≤0.165%.
The tensile strength of HCT780C steel is 780-950 MPa, the yield strength is 720-880 MPa, and the elongation at break is greater than 10%. This type of steel has high strength and toughness after hot-dip galvanizing treatment.
HCT780C steel is widely used in the automotive industry, especially in the production of main body frames, body shells, load-bearing frames, and other components. Due to its excellent welding performance and high strength, it can be used to produce automotive parts with high safety requirements. In addition, HCT780C steel is also commonly used in engineering machinery, construction, and metal structures.
HCT780C steel has high strength and excellent corrosion resistance because it is treated with hot-dip galvanizing, which can effectively prevent the oxidation and corrosion of the steel surface. In addition, it has good plasticity and weldability, which is convenient for processing and use.
However, HCT780C steel also has some disadvantages. Due to its high strength and hardness, it is difficult to process and shape. In addition, the hot-dip galvanized coating may melt and fall off in high-temperature environments, causing instability.
The most common forms of HCT780C steel include coils, steel strips, and steel plates, among others. Compared with the grades of steel from other countries, there may be some differences due to differences in steel grades and execution standards. For example, the European standard is HCT780C, the German grade is HDT780C, the American standard is ASTM A653/A653M-17 HCT780C, and it usually has similar properties to Xiangtan Iron & Steel HC780/980 steel.
To summarize, HCT780C steel is a high-strength hot-dip galvanized composite sheet mainly used in the automotive and engineering machinery manufacturing industries. It has high strength, excellent corrosion resistance, and plasticity, but also has the disadvantage of difficult processing and the possibility of falling off the coating. Different countries' grades and standards may have slight differences, and selection and comparison should be based on specific needs.
