摘要：
20GL steel (microalloyed with vanadium or titanium) is used for the production of rolling stock castings. In connection with this, a standard for microstructures are of value for production. The influence of manganese on yield strength. More than 0. 6% manganese promotes the formation of a lamellar bainitic structure consisting of ferrite and residual austenite or products of its decomposition. A higher manganese content causes embrittlement, especially at low temperatures.
