316 / 316L Stainless Steel Plate
Stellanox Steel delivers industry-grade 316 / 316L Stainless Steel Plates, known for their superior corrosion resistance, especially in chloride-rich and acidic environments. These molybdenum-bearing stainless steel plates are widely trusted for use in marine structures, chemical processing, and high-hygiene applications such as food and pharmaceutical equipment.
The low-carbon version, 316L, offers improved weldability and resistance to intergranular corrosion, making both grades versatile and highly reliable across aggressive service environments.
What is 316 / 316L Stainless Steel Plate?
316 Stainless Steel Plate is an austenitic alloy containing 16–18% chromium, 10–14% nickel, and 2–3% molybdenum, which gives it exceptional resistance to chlorides, pitting, and crevice corrosion. 316L, with reduced carbon content, prevents carbide precipitation during welding, ensuring structural integrity and corrosion resistance in welded assemblies.
Both grades maintain their strength and toughness at high temperatures and are widely used in architectural, industrial, marine, and sanitary applications.
