Check Analysis of Steel AMS 2259 - AMS 2248

For this episode we will delve into some of the finer points of chemical composition in steels.
Full Transcript: www.michlinmet...
Any alloy we name has a chemical composition associated with it. Common grade designations or complicated specifications have requirements for elements and are our starting point. You know how I am about specifications.
The chemical composition we see on the typical test report refers to the "batch" melted at one time.... called a heat. The final chemical analysis from the melt must conform to requirements. All requirements of the alloy and / or specification need to have reported values to show conformance.
Another type of analysis, called a check analysis can be performed to verify conformance of material or parts. Check analysis follows different rules and recognizes that additional variations in chemistry can occur that affect results.
An ADDITIONAL allowance is made to the required heat chemistry requirements ............ both under the minimum and over the maximum for each element.

Thank you, good info as usual.

Thanks for watching! Always appreciate the kind words. Not sure how many more of these I will be doing as 150 is in 2 weeks....that's 3 years. Got any ideas for more videos? :)

@@MichlinMetals yes, a misunderstood area of metals are powered metalurgy. Very often used in so Many products. I feel underwhelming long term results. Most connecting rods start out as powder. Also found in many product. With the emergence of sinter stations these materials will be found most everywhere. Thanks again.
