Testing the hardness of some 4140 square stock for Rockwell C scale. I’m using it to machine a custom tool for a customer. After machining I’ll use the Hot Shot 360 to heat treat it. #hardnesstester #4140 #abom79 | Abom79

🚨THE RESULTS ARE DEVASTATING 🇰🇷 A large-scale study out of South Korea analyzed 8.4 million people. 💉It compared vaccinated versus unvaccinated participants over one year. The results? Catastrophic. ⚠️ The study found a 27% overall increase in cancer risk in the vaccinated group. BUT it didn’t stop there.. By type of cancer: 👉 Breast: 20% 👉 Colorectal: 28% 👉 Gastric: 34% 👉 Lung: 53% 👉 Prostate: 69% 👉 Thyroid: 35% ‼️ These shots were marketed as “safe and effective.” The data now shows

The Rockwell scale is a hardness scale based on indentation hardness of a material. ... The result is a dimensionless number noted as HRA, HRB, HRC, etc., where the last letter is the respective Rockwell scale (see below). When testing metals, indentation hardness correlates linearly with tensile strength. | QA QC Professionals | Facebook
