With years of experience under their belt, they serve both local and global markets, providing reliable tubing solutions that promise performance and a long lifespan.
AISI 4140 Tubing is crafted from a chromium-molybdenum alloy steel, featuring a well-balanced mix of carbon (0.38–0.43%), manganese (0.75–1.0%), chromium (0.8–1.1%), and molybdenum (0.15–0.25%). This combination gives it fantastic hardenability, wear resistance, and tensile strength. It also boasts good toughness, fatigue strength, and impact resistance, making it perfect for heat treatment processes like quenching and tempering. With impressive yield and tensile strength, along with decent corrosion resistance, AISI 4140 Tubing is built to perform reliably under high-pressure and high-stress industrial conditions.
