Material:
30Si2MnCrMoV is a specific kind of steel alloy. It is a low-alloy high-strength steel commonly used in the manufacture of heavy-duty machinery, tools, and components that require high strength and toughness. The numbers in the name represent the composition of the alloy, including the percentage of various elements present in the steel.
