Product Introduction

316H tubing is a high-carbon variant of the 316 grade. The higher carbon content in 316H enhances its strength at elevated temperatures, making it suitable for high-temperature applications. It offers excellent resistance to a wide range of atmospheric, chemical, and marine environments. S31609 material can be welded using standard fusion and resistance methods, making it versatile for various industrial applications.

Comparison to 316 and 316L

316: Standard grade known for its general corrosion resistance and mechanical properties.
316L: Low-carbon variant designed to minimize the risk of carbide precipitation during welding, offering better corrosion resistance in welds.
316H: High-carbon variant providing enhanced high-temperature strength, making it suitable for applications where high mechanical performance is required at elevated temperatures.
