SUJ2
High Carbon Steel
Equivalent Grades: GB GCr15, JIS SUJ2, AISI 52100, DIN 100Cr6 (1.3505). SUJ2 has the great properties of bearings, such as wear resistance, toughness, hardness. Its workability and anti-fatigue strength are excellent as well. SUJ2 is widely used for the manufacture of plastic molds, ball bearings, steel ball, ball, bushings, shafts, guide rods, guide pins and other mechanical parts.
Bearing Steel
Purpose
SUJ2 is widely used in high carbon bearing steel.
