Okay, I was trying not to go down this rabbit hole but it’s apparently necessary.
This will not work. They have to trial from HIGH volume production material. Trialing from LOW volume production material will yield different results, in some cases hugely different results.
The recipe for a small batch of material is DIFFERENT than the recipe for a large batch of material. This is not double the recipe to make 4 dozen cookies instead of 2 dozen.
Part of these recipes beyond the actual elements is heating temperature, heating time, cooling time, funnel size and shape, distance to drop the molten metal, flow cadence, and on and on and on. It’s complicated, it’s intricate, it’s an art form. These recipes take as long as years to perfect.
And no, you can’t order from different suppliers. The recipes will vary even when starting with the same material parameters and thus the end result will be different causing variations in strength, formability etc...
Everyone can start with the same amount of eggs, flour, sugar but each batch of cookies will vary. Oven temperature varies, time cooking varies, the cookie sheet varies, was the dough worked by hand or with a beater, the amount of dough used to make the cookie. Try it. And now complex that times 100 for making steels.
