lead hardness testing st machining|Lead Testers : distribute On pure lead, the reading must be taken very quickly. Be extremely careful of the “point” (the part that touches the lead). This point has been calibrated and if it gets distorted or changed in any way, the reading will no long agree with this chart. If you have any issues, please contact ST Machining, LLC – (866) 428-5538 or e-mail us at The basic principle of steam sterilization, as accomplished in an autoclave, is to expose each item to direct steam contact at the required temperature and pressure for the specified time. Thus, .

Select “Sterilizing without an Autoclave.” The powdered agar medium bottle will have directions for preparing 1 L of agar. Divide the number of grams of powdered agar needed by 2 for the .
The tester point is NOT hardened, DO NOT test anything but lead alloys. Vagabond, I have one of the ST Machining testers, It is very well made and it .

They sold that portion of the business to ST Machining Products. SAECO and Cabine Tree testers measured the farthest from the actual lead hardness. Cabine Tree tools produced the smallest extreme spread, while the LBT tools produced the largest. If the LBT high test is removed, then the SAECO would appear to have the highest extreme spread. I am thinking about using a heavier spring to make a larger indent and using the standard Brinell hardness formula instead of comparing the results to pure lead. As I mentioned above, a 10 mm ball penetrator is the industry standard for Brinell hardness testing.
A SAECO Lead Hardness Tester will pay for itself many times over by allowing you to convert inexpensive scrap lead of unknown composition into casting alloy of known and reproduceable hardness. It provides a standard by which you can check the quality of purchased cast bullets.
To get a reliable and consistent dial hardness value, you need to have the exact same size ingot sample every time. Random clipping of a bullet nose or filing a flat will never offer repeatable results.
Testing the hardness of various lead alloys. There are numerous types of lead hardness testers available at reasonable prices. They use different methods o. Hi, folks, I am thinking it's time to get a lead hardness tester, and I would like one that works well, is repeatable, and is easy to use. I'm not worried about saving money nearly as much as I am about getting accurate results -- preferably within a . I have one really good recommendation for a hardness tester that provides the most versatile testing of lead alloys. It can be used with cast bullets, ingots, slabs, etc. It gives a BHN hardness result, which can be directly referred to.
For lead and lead alloys only. Wonder what hardness that alloy is? This tool will let you know quickly and easily!On pure lead, the reading must be taken very quickly.
