42CrMo4 Steel Pipe is a common Chromium-Molybdenum alloy steel that usually used after quenched and tempered. It offers a very good balance of strength, toughness. DIN 42CrMo4 Steel Pipe is used for automotive and aircraft components with high toughness as axle journals, gears, push rods, ring gears etc.
