  • Plain Carbon Steels: Classification and Limitations

    Commercial steels have carbon, normally, up to 1.5% maximum as the higher carbon content makes the steel extremely brittle. II. Though based on the carbon content, but classified according to the level of main mechanical properties of practical importance. This is the most commonly used commercial classification: i. Low Carbon Steels:CARBON FIBER,Classification of carbon fibers at the highest level is usually based on the tensile modulus and tensile strength of the fiber. Toray’s T series carbon fibers typically have high tensile strength and are classified by tensile modulus in standard modulus and intermediate modulus categories.

  • Composition, classification, and properties of petroleum

    A consequence of the wide variability of physical properties coupled with a very narrow range of composition is that carbon content cannot be used as a simple predictor of properties; in this respect, petroleum is very different from coal (Chapter 17).EC: Lesson 3.
