Webbcarbon content. Optical Emission Spectroscopy (OES) can detect carbon, but is only available in large, bulky carts, making it difficult to apply in awkward field environments (ladders, catwalks, ditches, tight spaces, etc.). Depending on the grade of stainless steel, carbon content can be between 0.005% to 1.2%. In certain stainless Webbbeds if unexpected emission lines are present in the signal. 405 410 415 420 425 430 0.0 0.2 0.4 0.6 0.8 1.0 Relative Intensity [a.u.] Wavelength [nm] 520 525 530 535 540 0.0 0.2 0.4 0.6 0.8 1.0 Relative Intensity [a.u.] Wavelength [nm] FIG 3: Differentiation of plain carbon steel and stainless steel through optical emission signals. 3.
