5140/41Cr4/40Cr alloy steel

5140 alloy steel (SAE standard), also known as 41Cr4 (EN standard) and 40Cr (GB standard), is a medium-carbon chromium alloy steel renowned for its good balance of strength, toughness, and hardenability. With a typical carbon content of around 0.40%, this steel grade is widely used in structural and mechanical applications that demand moderate strength with good wear resistance.
