Need Material for Hardened Pins
Need Material for Hardened Pins
(OP)
Hi all,
I'm working on a project to spec material for some 2" long 0.162" diameter hardened pins. The material must be in the form of drawing wire since there is a heading process to form a 5/16" diameter head (imagine a nail without a sharp point). The pins are then through hardened to 46-52HRC. I'm looking for the cheapest material to meet these properties. My guess is that a medium carbon steel should be sufficient. Any suggestions?

RE: Need Material for Hardened Pins
May I express the doubt that "the cheapest material" would not be the most fortunate qualifier for your project?
Until you sum up all expenses (procuring, delivering, receiving inspection, handling, heading, cutting, deburring, heat treating, descaling, finishing, packaging, storing and distributing) the material cost is likely to become a small fraction.
Not to say that production costs depend on lot size and degree of automation that is proper for the project.
May I suggest that you define completely your product and then request a number of RFQ (Request for Quotation) for definite lot sizes? Definite answers would give you the orientation you seem to be looking for in your query.

RE: Need Material for Hardened Pins
To reach this hardness after temper you probably need 45C or more.
If you used a lower C alloy and the carburized or nitrided to get case hardness it might be less expensive, then Q&T.
You need to talk to a fastener house, someone that cold heads and heat treats.

This heat treat will give good hardness with reasonable toughness. A good option.
