Alloy: 316 | Material: Stainless Steel | Shape: Bar-Square | Production Method: Cold Finish | Height: 0.125 Inches | Item Length: 36 Inches Stainless Square Bar 316 exhibits high strength and excellent corrosion resistance including in marine environments. 316 is slightly stronger than 304 stainless and is rated as a marine metal. 316 maintains its properties in cryogenic or high temperatures. It is typically used in oil and petroleum equipment, aerospace, food processing, pulp and paper processing equipment, textiles, architectural, and marine equipment. 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.
