Martensitic 420A/420B/420C/440C Stainless Steel Balls
Crafted from high-carbon alloys (e.g., 420, 440C), these balls achieve exceptional hardness through quenching and tempering, ideal for wear-resistant applications like surgical tools, precision bearings, and cutting instruments. While less corrosion-resistant than austenitic grades, their unmatched strength suits dry, high-stress environments demanding durability over rust-proofing.
