AISI 316 Stainless Steel Disk

AISI 316 Stainless Steel Disk combines high corrosion resistance, mechanical strength, and structural stability, making it suitable for applications in aggressive chemical, marine, and high-vacuum environments. The presence of molybdenum enhances resistance to pitting and crevice corrosion, while its austenitic structure ensures good formability and weldability. This disk form is used in precision instrumentation, chemical processing equipment, and biomedical device components where dimensional accuracy and material purity are critical. Specific uses include sealing plates in high-pressure pumps, flanges for pharmaceutical reactors, and substrates for thin-film deposition systems. In research, AISI 316 disks serve in tribological studies, surface modification experiments, and additive manufacturing trials for high-energy physics applications. The material’s combination of durability, corrosion resistance, and versatility ensures value in both industrial manufacturing and scientific innovation.
