Metal Composition: Analysis , Tests and Charts

The spark metal composition test is a method of classifying steels and iron according to their composition by observing the sparks formed when the metal is held against a high speed grinding wheel. This test does not replace chemical analysis, but is a very convenient and fast method of sorting mixed steels whose spark characteristics are known.

Sparks During Grinding | BladeForums.com

 · When grinding knives, the plain carbon steels spark a lot, and an experienced eye can judge from the spark pattern the type of steel it is! Stainless steels can spark, but from my experiences of grinding C and ATS (and other steels just in sharpening), they don't spark that much. They don't spark at all in sharpening as per my methods.

Cast Iron vs. Cast Steel Test

 · With out taking samples and sending them to a Lab the Spark Tree test (grinding) is the most reliable. The Carbon content makes for a very large Spark Tree very close to the grinding wheel where as the Cast Steel's Spark tree is sparser with longer tails. Also the Graphite (as mentioned) is a very good indication of Cast Iron.

spark test can easily be performed on most metals. This test involves lightly holding the metal against a grinding wheel and observing the characteristics of the spark stream. As carbon in the metal unites with oxygen in the air, it begins to burn; therefore, the more carbon the metal contains, the greater the amount of sparks will be observed.

Metal Identification Tests

A spark test is one of the most common types of tests for identifying material. It's done by holding a piece of metal against a grinding wheel and making it spark (or not). A veteran fabricator can tell what the metal is simply by looking at the type of sparks, or lack thereof.

steel specimen and the grinding wheel. By attaching a custom built arm to the eight inch bench grinder, the force on the grinding wheel was kept at a constant force of 3.3 Newtons. This meant that any variation in the spark stream would be due to a variation in the steel/cast iron instead of the force applied to the specimens.

good metals to make knives from? | BladeForums.com

 · If you want cheap steel to practice forging techniques or grinding techniques, just get plain old mild steel. if you are looking to make a heat treated knife, get a known steel, I would suggest 1075, 1095, or W2 to start. when you break it down, none of these steels should be more than $1.00 for a hunter/utility, especially if you are forging.
