Grade: AISI 302
Formula: Fe/Cr 18/Ni 8
Form: Coil
Material: Stainless Steel
Commodity: Alloys
Temper:
Hard
AISI 302 Stainless Steel Coil is an austenitic stainless steel coil known for its high corrosion resistance, excellent ductility, and good work-hardening capability. Its composition allows it to achieve significant increases in strength through cold working, making it adaptable to demanding mechanical applications. In coil form, it is widely used in precision springs, industrial fasteners, and automotive components, where both resilience and corrosion protection are required. Specific applications include spring coils for aerospace and automotive assemblies, chemical-resistant gaskets, and high-durability clamps. In research, AISI 302’s metastable austenitic structure and strain-induced martensitic transformation make it valuable for studies on wear resistance, fatigue life, and advanced surface modification, such as plasma immersion ion implantation or molten salt siliconizing. The alloy’s combination of mechanical adaptability, corrosion performance, and manufacturability secures its importance as a reliable engineering material for scientific and industrial innovation.
