Stainless Steel Sheet

Stainless steel sheet, an indispensable material across a wide array of industries, is esteemed for its remarkable properties, such as unparalleled corrosion resistance, durability, and formability. This detailed description provides a comprehensive overview of the versatility, applications, and technical specifications of stainless steel sheets, specifically focusing on the SS grades 202, 304, and 316.

Understanding Stainless Steel Sheet Grades

SS Grade 202: - Composition: Grade 202 stainless steel is an austenitic chromium-manganese alloy, with moderate levels of nickel. - Properties: It offers an excellent combination of strength and toughness, with decent corrosion resistance in mild environments. - Applications: Commonly used in food service equipment, kitchen appliances, and architectural facades.

SS Grade 304: - Composition: This grade is an austenitic stainless steel consisting of 18% chromium and 8% nickel. - Properties: Known for excellent corrosion resistance, good forming properties, and weldability. This grade withstands a wide range of atmospheric environments and corrosive substances. - Applications: Predominantly found in chemical containers, heat exchangers, and various food industry components.

SS Grade 316: - Composition: Grade 316 contains a higher level of molybdenum (2-3%) along with chromium and nickel – enhancing its corrosion resistance, particularly against chlorides and other industrial solvents. - Properties: Exhibits superior resistance to pitting and crevice corrosion; maintains strength and toughness even at elevated temperatures. - Applications: Frequently used in the marine environment, chemical processing, and pharmaceutical equipment due to its exceptional chemical and chloride resistance.

Key Properties of Stainless Steel Sheets
