Frequently Asked Questions
How does 410 compare to 420?
410 has lower carbon (0.15% max vs 0.15-0.40% for 420), making it slightly more ductile but less hardenable. 410 typically reaches 40-45 HRC maximum vs 50-55 HRC for 420. Choose 410 for better toughness and weldability; choose 420 for maximum hardness.
