Frequently Asked Questions

What is the hardness of 60 Plus® C1060 material?

The hardness of 60 Plus® C1060 material is 60 to 65 on the Rockwell C scale.

What is the hardness of 50 Plus® 440C stainless material?

The hardness of 50 Plus® 440C material is 50 to 55C on the Rockwell C scale.

Is 50 Plus 440C shafting magnetic?

Yes, in order to harden this grade of stainless steel there needs to be some iron content which is magnetic.

What is the standard length tolerance for cutting?

The standard tolerances are +/- 1/32″ on the 1/4″ through 1-1/4″, +/- 1/16″ on 1-3/8″ through 2″, and +/- 1/8″ on 2-1/2″ and 3″. Tighter tolerances can be maintained at additional cost.

Can I check to make sure my shafting is hard by using a file.

No. A file is about 70 Rockwell C scale for the hardness. 10 points is a big difference and will scratch case hardened steel.

Can I machine the hardened steel myself?

Only if you are familiar with the required machining operations. It can be difficult if you are not. The Lee 60 Plus® shafting offers the highest machine-ability in case hardened steel.
