Expanite® is a leading brand that specializes in surface hardening and wear resistance solutions for a wide range of alloys. With a focus on austenitic, martensitic, ferritic, and duplex stainless steels, as well as nickel-based and cobalt-chromium alloys, Expanite offers innovative treatments to increase surface hardness and enhance durability. Whether you're dealing with Austenitic 201 / 301 / 303 / 304 / 305 / 308 / 310 / 316 / 904, Martensitic 420 / 440 / 17-4PH / 17-7PH, Duplex 2205 / 2507, or Ferritic 430 / 431 / 434 alloys, Expanite has the expertise to provide tailored solutions for your specific needs.

Expanite offers three main treatment processes: ExpaniteHigh-T, ExpaniteLow-T, and SuperExpanite®. These processes aim to dissolve nitrogen and carbon in the surface of stainless steel, resulting in increased hardness and wear resistance. The Expanite process creates a diffusion zone known as expanded austenite or expanded martensite.

With a focus on quality assurance and a diverse range of applications in industries such as pumps and valves, food and beverage, automotive, oil and gas, medical devices, aerospace and defense, consumer goods, and general industry, Expanite is the trusted choice for surface hardening solutions.
