We offer camshafts from a variety of steel types. Most builders of high output engines prefer carburized 8620 or 9310 steel types. For induction hardened camshafts you have a greater choice with 1050, 5150, or 5140. There are other alloys being induction hardened but we can’t see a great advantage. With today’s spring pressures and RPM range, camshafts are being asked to do more than ever before. It is always important to verify the steel you are using meets cleanliness and micro structure standards, not just alloy content. The Callies metallurgical can evaluate these characteristics, making sure the end user gets the durability they are looking for.
