Use a grinding wheel that has a hardness to last for some time, but soft enough to maintain a free cutting edge. Conduct spark tests in little light to make it easier to see the spark color. As a recommendation, use standard metal samples when comparing sparks with test patterns. When ho...
The reason all steel product manufacturers use the Rockwell hardness scale is that it allows uniformity in reporting test results. Everyone in the steel industry recognizes the Rockwell hardness scale. They quickly know steel strength from a glance at its Rockwell rating. The Rockwell system is univ...

Anodizing also hardens the part’s surface up to Rockwell 70C, which ensures the part can handle a lot of use. Because anodized parts are so durable, they don’t often require oiling, conditioning or repainting. Additionally, hard-anodized aluminum is an electrical insulator and serves as a ...

8670 is very easy to work with and it is forgiving in heat treatment. It has very good toughness as well. My recommended heat treatment is 1500°F for 10 minutes, quench in fast or medium oil, and temper between 300 and 450°F depending on the desired hardness. This article also has ...
How to Make a Knife: I love to design and make things – it’s my passion! One day at work by boss showed me a picture of a kitchen knife he made completely from scratch and after that, I knew I had to make one. He said it was “one of the most rewarding
ROCKWELL HARDNESS TEST. A method for determining the relative hardness of a metal by impressing a diamond indentor, or a 1/16" or 1/8" ball into a ground surface with a prescribed load not exceeding 150Kg. This test is normally used on small hardened parts, or on surfaces where the lar...
