300 Series Stainless Steel Material Properties

SS 300 stainless steel is an ideal material for use in chemical and petrochemical industries that require equipment to withstand high temperatures and corrosion, such as acidic and alkaline foods and solutions, making it suitable for food products. Furthermore, its resistance to such foods makes SS 300 suitable for the food industry as it’s easy to clean and hygienic cleaning procedures help preserve product quality while being inexpensive yet highly formable with better formability than 200 series martensitic or ferritic duplex stainless steels and forms than martensitic duplex stainless steels as well as nonmagnetic.
