As a materials engineer with over fifteen years immersed in metallurgical applications, I constantly witness the indispensable role medium carbon steel plays. Sitting strategically between low and high carbon variants, this alloy family delivers an exceptional balance of strength, toughness, and machinability that few materials can match cost-effectively. From the axles propelling your car to […]

Carbon steel grades are primarily classified based on carbon content, which directly influences their mechanical properties and applications. Carbon steel is an alloy of iron and carbon with up to 2.1% carbon content. 1. Low-Carbon Steel (Mild Steel) Carbon Content: 0.05–0.25%. Properties: High ductility, excellent weldability, and machinability; low hardness and strength. Cannot be hardened via

In my experience, the primary distinction between Schedule 40 and SS 40 pipe stems from their material makeup and intended applications: Schedule 40 typically denotes carbon steel pipes manufactured under ASTM A53 standards, whereas “SS 40” refers to stainless steel pipes conforming to ASTM A312, delivering enhanced corrosion resistance at a comparable wall thickness (e.g.,
