Stainless Steel Sheets & Plates
Product Overview
R V Metal Corporation supplies stainless steel sheets and plates across a broad grade spectrum—economical 200-series (J4, J7, 201, 202), high-strength work-hardening grades (301, 302), the most common austenitic workhorses (304, 304L, 304H, 305), higher corrosion-resistant molybdenum-bearing grades (316, 316L, 316H, 316Ti, 317, 317L), stabilized grades for elevated-temperature service (321, 321H, 347, 347H), heat-resistant grades for oxidation and thermal cycling (308, 309, 309S, 310, 310S), ferritic and martensitic options for cost, magnetism, and wear/strength (409L, 410, 410S, 420, 429, 430, 430Ti, 439, 441, 444), and Duplex S31803 for high strength with excellent chloride stress-corrosion cracking resistance. Sheets are typically selected for fabrication and lighter structures where forming is critical, while plates are preferred for heavy-duty fabrication, pressure parts, base plates, and structural applications where thickness, flatness, and weld stability matter. Available in hot rolled (HR) and cold rolled (CR) conditions and multiple surface finishes, these products are suited to general fabrication, architectural cladding, chemical and process equipment, food and dairy, heat exchangers, tanks, marine service, and industrial OEM requirements—where grade selection is driven by corrosion environment, temperature, weldability, and required mechanical performance.

Note: The above chemistry values are typical industry ranges commonly used for datasheet guidance. Actual limits depend on the governing standard (ASTM/EN/JIS/IS) and mill practice. For J4/J7 (trade grades), chemistry may vary by producer; confirm with the Mill Test Certificate (MTC) for project-critical use.
