316/316L Stainless Steel: Properties, Applications & Marine Grade Solutions
Known as "Marine Grade," 316 stainless steel contains Molybdenum, providing superior resistance to chlorides and pitting. 316L is the preferred choice for heavy-gauge welded components. Jinling specializes in high-purity 316L for pharmaceutical and coastal projects where long-term durability in harsh environments is non-negotiable.
Forms selection
Available options
Choose stainless steel grade by product form and surface finish, including coil, sheet and plate, bar forms, tube and pipe, plus 8K mirror, AFP anti-fingerprint, No.4 brushed, hairline, 2B, and BA finishes for fabrication, architecture, appliance, marine, and industrial projects.
Specifications
Marine-grade stainless steel for chloride resistance

316 / 316L specification
Compare 316 and 316L stainless steel specification data for marine, coastal, pharmaceutical, chemical, and welded fabrication projects. Molybdenum alloying improves pitting resistance in chloride service, while 316L supports welded parts requiring better resistance to sensitization.
Typical values are for buyer comparison; final supply follows the order standard, mill origin, and MTC.
