The reason is the fine-grained structure of higher strength steels. Due to the small size of grains, there is a higher possibility for trapping of hydrogen atoms in its structure. Conversely, in large grain structures, it is easy for hydrogen atoms to escape out from it.Cited by: 100Publish Year: 2017Author: Satish Kumar Sharma, Sachin Maheshwarisp.info Metallurgy Matters: Making steels strongerOct 09, 2003 · Fine grain size offers better toughness and ductility. Austenitizing temperatures higher than 1,800 degrees F generally cause a coarse austenitic grain structure, and these coarse-grained steels are usually inferior to fine-grained steels in terms of strength, ductility, and toughness.Estimated Reading Time: 7 mins
