I used a couple of Burlington cranks for members in our club. We do a lot of driving, so far they have been trouble free. Being a old machinist that has used a lot of 4140 and some 4340 which is stronger than 4140 you will have a hard time finding a better material. We used 4140 for piston rods in cylinders up to 24" bore. It is not even close to 1040 if that is what he was talking about. Cold rolled steel does not mean much. You need the number.
