Web19 de jul. de 2024 · O1 High Hardenability Steel. O1 with its very high hardenability there was no difference between Parks 50 and canola: There is a small difference in hardness between the two oils shown above, however. This is likely due to “auto-tempering” which is a small amount of tempering that occurs by slow cooling through martensite formation. Web13 de jan. de 2024 · For example, for very heavily loaded vehicle components and machinery component parts requiring high hardenability by carburization, steels with nickel, molybdenum and chromium alloys are now being recommended.
