Another consideration may be the effects that heating can have on the stainless. What alloy stainless are you dealing with? Sensativing the material can caould a reduction in the corrosion resistance of some mateirals. If this is the casue you may need to consider a therrmal treatment after...
There may be few things worth considering:
1. The transformation of retained austenite will cause small dimensinal changes, more significant in higher carbon alloys. Most application where this is a real concern are heat treated for maximum stability, using some combination of sub zero...
There are many around, I'm not sure where you are located, but I've had good success with Mass. Material Research in West Boylston, MA. or IMR in Ithaca, NY

ASTM also publishes a list of test labs, covering many different fields...
There are also specs that control the depth of surface defects, such as laps, decarb and other items. Often people will evaluate the size part the want to mfg. then see the defect depths that are permissible and add that to the stock sizr, plus a bit of a safety factor. One spec that deals...
There are a wide variety of industry standards that address tolerances for bar product, based on finish conditions (hot rolled, cold finished, ground, etc.)
You may want to look at some of the ASTM specifications, these are generally separated by product type, and the tolerances will be within...
I know there are a number of standards for acid etch inspections, such as AMS-2649, MIL-STD-867 or ANSI B3.3 - I'm not sure if they specifically address high temp steels. They may be a starting point....
I have many components that get silver plated, per either AMS-2410 or AMS-2412. I have tried to do some microhardness testing to determine the hardness of the plating, but get values that are suprisingly low.
Anyone have a rough idea of how hard I should expect the plating to be?? Any info...
I currently work with a vacuum tempering furnace manufactured by a company called Japan Hayes, located in Japan. As I understand it there was a licensing agreement with C. I. Hayes of Rhode Island, but that C.I. Hayes has nothign to do with this company. I am interested if anyone else is...
I'm evaluating some different rust preventative oil and need to better understand the impact and effects of volatile organic content. I am concerned that products with a higher VOC content will provide less protection, due to the evaporation of the volatiles.
If a product has a higher VOC...
Various types of vibration monitors are typically used to aid in identifying the cause of chatter, as RamingtonStall indicated. We typically look at various frequencies and base line critial machines to identiy potential problems early. They can also be used to fine tune a process to avoid...
I have used Atlas Speciality Steel, Welland Ont. for this grade, not sure of their size/shape capabilities.
Also, you may want to try Universal Stainless and Alloy, Brdigeville, PA.
It is fairly important to properly cool 440C to aviod carbide precip at the grain boundaries. There are a number of documents that give good guidelines, AMS-Mil-H-6875 or AMS-2759. Generally, if 440C is cooled too slowly from the hardening temp. through about 1100F, you will get precipitation...
There are several hand held portable devices that work well for alloy sorting and the like. They are however XRF technology. One company is Innov-X Systems of Woburn, MA
(www.Innov-Xsys.com)
I have also seen alloy soritng kits that use different acid solutions to seperate between at least...
