403 stainless steel, also known as UNS S40300, is classified as a martensitic stainless steel featuring high chromium and low carbon content. It is widely utilized in applications that demand high strength and corrosion resistance.
403 stainless steel bars are well-suited for use in demanding environments due to their good corrosion resistance. They also exhibit favorable mechanical properties, including high hardness, toughness, and wear resistance. However, it’s important to note that these bars may not offer the same level of corrosion resistance as other stainless steels such as 304 or 316, and may not be suitable for use in extremely corrosive environments. The presence of Nickel enables 403 stainless steel to achieve a complete austenite structure, resulting in higher strength, plasticity, toughness, excellent hot and cold workability, cold formability, and weldability. Additionally, it enhances the thermodynamic stability of 403 stainless steel.
