Typically there is less than 0.40% carbon in most steels, though it is possible to...Common Metal Identification Methods
The ability to identify metal is a valuable skill for many operations such as welding, machining, cutting, and fabricating. Metal workers use various methods, from traditional to modern ones, to identify the scraps and sheets of metals that come into the shop. In...Setting PMI Test Standards
What are standard operating procedures? Standard operating procedures are detailed instructions on how to carry out a particular job. For positive material identification, PMI testing, these instructions will describe exactly how the sample is to be prepared, what...
