Steel Alloy Machining Characteristics

Steel Alloy 4140 or 4142
Steel alloys 4140 & 4142 are commonly machined for higher stress applications that need the strength of an alloy. Direct hardening only.
Steel Alloy 41L40
Steel alloy 41L40 is designed for better machining with lead additive. Direct hardening only. Alloy 41L40 is typically machined into components for higher stress applications.
Steel Alloy 8620
Steel alloy 8620 is comprised of .55% Ni, .50% Cr, .20% Mo. Case hardening and heat treatable. Alloy 8620 is machined into parts for higher stress applications which require the strength of an alloy.
Steel Alloy 52100
Steel alloy 52100 is comprised of very high 1% carbon, .25% Ni, 1.4% Cr, .08% Mo. It is commonly machined for bearing applications.
