did krupp make various types of shotgun barrel steel at the same time or was it all pretty much the same formulation...

have always been amused at parker and their various barrel steels...

see new thread...

Ed, the answer to your question is already within this Thread... if you had been paying attention.

Krupp was a large integrated steel maker. They were not a barrel maker. Over the years, barrel makers who wanted to build barrels out of high quality steel chose names like Krupp, Bohler, Whitworth, etc. When they ordered their steel, they could choose from various grades of steel with different analysis, composition, and machining qualities.

When they completed their barrel, they could justifiably stamp it with the name of the steel it contained. But Krupp steel barrels produced by one barrel maker could be quite different than Krupp barrels produced by another barrel maker. They were likely similar, because barrel makers and gun manufacturers desire similar qualities of strength, machinability, corrosion resistance, etc. But without testing them all, there is no way to know.

This is why sending out one or two samples for metallurgical analysis really tells us nothing but vague generalities. And even the steel purchased by the same barrel make at a different point in time could have a different composition. You would have to have access to every purchase order for barrel steel from every barrel maker to know exactly what grade of Krupp steel they used.

Just remember, pure elemental gold or pure elemental iron will always be gold or iron. But steel is a generic term for an alloy, with literally thousands of different formulations. As such, no two heats will ever be perfectly identical in analysis or composition, under normal modern methods of steel manufacturing. Final analysis was even less precise a hundred years ago. But I could probably impress the hell out of you with a bunch of copy-and-paste pictures, advertisements, and random analysis.


A true sign of mental illness is any gun owner who would vote for an Anti-Gunner like Joe Biden.

well, keith, that clarifies and condenses things for me, thank you...

which brings us back to an old topic..re heat treating of shotgun frame parts, in a vain effort to duplicate long faded factory case colors...

considering that frame metal alloys varied through time and manufacturer, plus original heat treating specs for most gun makers have been lost, one must conclude that those engaging in the black art of shotgun frame parts re heat treating are only guessing as to their practices, based on their experiences, based on trial an error...

least, that is what old ed taught me...
