Testing is an important parameter in metallurgical sciences. The performance and properties of grade 304 can be assessed with the various testing procedure. The qualitative and quantitative tests can be performed to test grade 304. Few tests are potable and some of the tests require laboratory confirmations. A laboratory test can determine the hardness, tensile strength, etc.
Chemical test
Instrumental test
Instrumental tests are expensive.
An electrical spark is generated and the concentration of elements is depicted by the intensity of specific colors.
This test allows for the identification of chemical composition. Grade 304 has the main composition of chromium, nickel, and other alloying agents.
