AISI 316h Stainless Steel Round Pipe Price (latest 2025)

What Is AISI 316H Stainless Steel Round Pipe?

AISI 316H is a high-carbon version of 316 stainless steel (carbon content 0.04–0.10%), specifically designed to deliver higher strength at elevated temperatures. Compared with 316L, 316H provides better creep resistance and tensile stability, making it ideal for heat exchangers, boilers, petrochemical piping, and power generation systems.

AISI 316H Stainless Steel Round Pipe Price (Latest 2025)

The latest price for AISI 316H stainless steel round tubes (2025) is currently US$5.50-9.50 per kilogram, with prices varying depending on diameter, wall thickness, surface finish, and order quantity. Larger seamless tubes (DN200-DN600) are priced closer to the upper end of the range (approximately US$7.90-9.50 per kilogram).

Pipe Type	Price Range (USD/kg)
Seamless 316H Pipe	USD 5.8 – 9.5 / kg
Welded 316H Pipe	USD 4.9 – 8.2 / kg

 

What is the difference between 316H and 316L stainless steel pipe?

316H has higher carbon (0.04-0.10%) for increased strength at high temperatures, making it great for furnaces, while 316L has lower carbon (max 0.03%) for excellent weldability and corrosion resistance, ideal for welded systems in marine or chemical use. The key difference is carbon content, which dictates application: H for high-temp strength, L for weld-corrosion resistance.

Is 316H stainless steel suitable for high-temperature service?

Yes, 316H stainless steel is specifically designed for high-temperature applications. Due to its higher carbon content compared to standard 316 or low-carbon 316L stainless steel, it exhibits superior strength and creep resistance at elevated temperatures, making it an ideal choice for components in petrochemical, power generation, and furnace equipment. Depending on the specific environment, its continuous service temperature typically reaches around 800-870°C (1472-1598°F).
