In this article, we will ** a martensitic aging steel with excellent mechanical properties, namely 00Ni18CO9Mo5Tial Round Bar C300 Plate 022Ni18CO9Mo5Tial Forging 18Ni (300) GR73 Forging Ring 18Ni1900. First, let's understand the chemical composition of this steel.
The chemical composition of the steel is mainly iron, but it also contains moderate amounts of nickel, cobalt, molybdenum, titanium and aluminum. Among them, the nickel and cobalt content is 18-19% and 8., respectively5-9.5%, the presence of these elements gives the steel a high strength and hardness. In addition, the steel contains 46-5.2% molybdenum and 05-0.8% titanium and aluminum, these elements improve the corrosion resistance and toughness of the steel. The content of phosphorus and sulfur does not exceed 0., respectively01% and 001%, the content of silicon and manganese does not exceed 01% and 01%, the limitation of these elements guarantees the purity and mechanical properties of the steel.
Next, let's ** the mechanical properties of this steel. The solution temperature is 815-830, the aging temperature is 480 5, and the hardness of the steel can reach HRC53-54 after aging treatment. In addition, the tensile strength is 2060, the yield strength is 2010, the elongation after fracture is 12, and the section shrinkage is 60. These excellent mechanical properties make the steel excellent in the face of high loads and high temperatures.
In practical applications, this martensitic aging steel is widely used in aerospace, automotive, petrochemical and other fields. Due to its high strength, high hardness, corrosion resistance and good toughness, it can maintain excellent performance under various complex environmental conditions.
In a word, 00Ni18CO9Mo5Tial C300 022Ni18CO9Mo5Tial 18Ni(300)GR73 18Ni1900 martensitic aging steel is a special steel with excellent mechanical properties, and its chemical composition and mechanical properties make it widely used in various fields.
