Re: Different types of spur gear stock
It doesn't say on the website but you could definately call or email mcmaster-carr and I'm sure they could tell you what type of steel it is.
You will need to make sure to match the pressure angle of the gears to the stock that you are ordering. The SDP gear stock is listed as having both 14-1/2 degree pressure angle and 20 degree pressure angle. The Mcmaster-Carr stock is listed only as 20 degree pressure angle. It is not a good idea to mismatch these and the life of the gear teeth with be reduced and they will not mesh properly. |

Re: Different types of spur gear stock
Go over to http://www.efunda.com/ and look up 12L14 steel and 1018 or some such mild steel. 12L14 has some lead content to make it easy to machine. It's not 4140 pre-hard or "stressproof" steel by a long shot.
