AMH chain pins are made from low alloy steel and are case hardened. Pin core hardness has a range of 300-400 BHN with an outer surface hardness of 62HRC to a depth of 0.040″.
AMH can also supply clamp washers in mild steel or stainless steel based on your application. We can also offer pins in martinsitic or precipitation hardened alloys such as AISI420 and 17-4PH stainless steel.
Stainless steel pins and clamp washers should be considered in any wet ash or hogfuel applications.
