Alloy: Nitronic 50 | Material: Stainless Steel | Shape: Round Bar | Diameter: 2.5 Inches | Item Length: 12 Inches Stainless Round Bar N50, also called "Nitronic 50", has exceptional wear, galling resistance, and corrosion resistance superior to 316 stainless. Designed as an all-purpose steel, it is a fully austenitic alloy that maintains its physical properties at elevated and sub-zero temperatures. Additionally, N50 has about twice the yield strength of 304 and 316 stainless. It is typically used in fasteners, pins and bushings, wear rails, roller bearings, pump components, and other marine environments. Stainless steel is an iron alloy with resistance to staining and rusting in many environments where steel would typically degrade. The chemical composition of each grade creates a grain structure that falls into one of five classes: austenitic, duplex, ferritic, martensitic, and precipitation hardening. The austenitic class contains the most formable, weldable, and corrosion-resistant stainless-steel grades, but they cannot be heat treated. The duplex class offers high resistance to pitting and chloride stress corrosion cracking. Duplex grades are heat treatable and roughly twice as strong as austenitic grades. The ferritic class contains moderately formable and corrosion-resistant grades compared to other stainless steel classes, but they cannot be heat treated. The martensitic class includes some of the hardest and strongest stainless-steel grades that also offer mild corrosion resistance, high hardness, and good formability. Martensitic grades can be heat treated. The precipitation-hardening (PH) class can be heat treated after fabrication to achieve some of the highest hardness ratings in stainless steel.
