Grade: AISI 302
Formula: Fe/Cr 18/Ni 8
Form: Disk
Material: Stainless Steel
Commodity: Alloys
Temper:
Hard
AISI 302 Stainless Steel Disk is an austenitic stainless steel variant known for its high tensile strength, excellent corrosion resistance, and durability across a wide temperature range. Its higher carbon content compared to 304 stainless steel provides increased strength and hardness after cold working while maintaining significant ductility. In disk form, it serves in chemical processing, marine engineering, and precision instrumentation industries for wear-resistant components, sealing interfaces, and corrosion-proof structural parts. Specific applications include precision mechanical spacers in corrosive fluid systems, high-strength supports in marine sensor housings, and durable contact surfaces in laboratory apparatus. In research and innovation, AISI 302 disks are used to develop advanced cryogenic components, fatigue-resistant designs, and high-performance structural interfaces for demanding environments. The alloy’s combination of mechanical resilience, corrosion protection, and dimensional stability under varying service conditions ensures ongoing value in high-performance scientific and industrial uses.
