Products Description
Features and Advantages
316H stainless steel plate is distinguished by its higher carbon content (0.04-0.10%), which enhances its creep strength and structural stability at temperatures up to 800°C-making it far more durable than standard 316 in long-term high-heat operations, such as chemical processing furnaces, exhaust systems, and power plant components. Like other 316 grades, it contains molybdenum (2.00-3.00%), delivering superior resistance to chloride-induced pitting and crevice corrosion, ideal for marine, coastal, or chemical plant settings. Its austenitic structure also ensures excellent ductility and weldability, allowing for easy fabrication into complex shapes without compromising performance. Additionally, 316H plate maintains consistent mechanical properties across a wide temperature range, from sub-zero environments to extreme heat, ensuring reliability in diverse industrial scenarios.

FAQ
1. What makes 316H plate different from standard 316?
316H has higher carbon content (0.04-0.10%), enhancing high-temperature creep strength, making it ideal for long-term use above 600°C, unlike standard 316.
2. Can 316H plate be welded?
Yes, it maintains good weldability with proper techniques (e.g., using matching 316H filler metal) to retain high-temperature performance.
3. What certifications are available for 316H plate?
We provide ASTM, CE, JIS, and ISO certificates, plus MTCs with full chemical and mechanical test data.
4. What's the minimum order quantity?
1 ton for standard specs; 5 tons for custom sizes/thicknesses.
5.How is 316H plate packaged for shipping?
Standard: PE film + fumigated wooden pallets. For high-precision orders: moisture-proof paper + wooden crates to prevent scratches.
