Grade B cast iron specifications

Post by John E. Guitar » Wed Mar 29, 2023 4:44 pm

The valve head drawing (15th Jan 1927) lists the material as Grade B cast iron. I'm wondering if anyone has the specifications on this material?

I've seen other threads referencing "Shop Theory - The Henry Ford Trade School" listing the composition of EE steel and other materials. Does anyone have a copy of this that could check?

I'm not a student of turn of the century material specs, but presently, ASTM A126 covers Cast Iron grades A, B, C, with respect to tensile strength.

I suspect but am not certain, that this will directly trace back with relevance to the FORD spec in some fashion.

amendment to my post: a quick look shows that ASTM goes back to late 1890's so this FORD standard (B) is almost certainly an ASTM callout as I posted above, regarding Tensile Strength

Ford Methods and The Ford Shops (1914, pages 346-347) states analyzes of the iron used in the T-400 cylinder blocks. Silicon 2.00; sulphur 0.06-0.08; phosphorus 0.20; manganese 0.65. Also among the listings for components in the iron castings include the T-418 pistons, and the T-4490 valve heads.

The valve heads used 1 set of moulding machines, casting 400 pieces from that set, 40 pieces in each mold. Would assume the iron type used for the cylinder blocks would be same type iron for the valve heads that contact that block

Thank you Scott & Dan.

I found Ford Methods and The Fords Shop on archive.org. That looks like it's full of great information. I'll keep an eye out for an original copy.
