For buyers and engineers in South America, Russia, Southeast Asia, the Middle East, and South Africa, selecting between martensitic and bainitic hardening can mean the difference between unplanned downtime and years of reliable service. This article breaks down the science, selection criteria, and regional application insights you need to make an informed decision in 2026. What Is Martensitic Hardening and How Does It Work? The Science Behind Martensitic Transformation in Bearing Steel Martensitic hardening is the most widely used heat treatment for bearing steels such as AISI 52100 […]
