Corrosion resistance of Super13cr stainless steel round steel for drilling tools
Super13Cr is a martensitic stainless steel with good corrosion resistance and excellent strength, mainly used in offshore oil projects, OTG pipelines, casings, and underground projects. It is a super stainless steel that improves its strength and hardness, as well as toughness, by reducing the carbon content (carbon content is 0.03%) and increasing the nickel content (4.5-5.5%) and molybdenum content (1.5-2.5%). This material overcomes the shortcomings of traditional martensite such as poor stress crack sensitivity and poor weldability during welding, and therefore has higher corrosion resistance and better welding performance. Super13Cr has a wide range of applications, including but not limited to automotive, metal products, precision electronics, mechanical manufacturing, pressure vessels, chemical equipment, etc.

- Steel round bars exhibit excellent performance under vibration or resonance, thanks to their high strength and stiffness. The inherent properties of steel, including its high modulus of elasticity and low damping characteristics, make it an ideal material for applications involving vibration or resonance. When subjected to vibration or resonance, steel round bars show minimal deformation or deflection. This is because steel possesses a high natural frequency, allowing it to resist external forces or vibrations effectively. Additionally, the high stiffness of steel helps it maintain its shape and integrity in such conditions. Moreover, steel round bars have good fatigue resistance, enabling them to withstand repeated loading and unloading cycles without significant performance degradation. This is particularly crucial for applications involving cyclic loading or vibrations over an extended period.
