Description: 4140/42 and 4130 Mechanical Tubing are medium carbon alloy grades, widely used for general-purpose applications requiring high tensile strength and toughness. The addition of chromium and molybdenum, combined with professional heat treatment, provides superior hardness, ductility, and strength.
Delivery Conditions:
Alloy steel round 4140 tubing (Chromoly steel) is renowned for its exceptional strength and resistance to fracturing, abrasion, and impact in high-stress industrial applications.
