Stainless Steel 316H Pipes
At ASC LLP, we pride ourselves on offering top-quality stainless steel products to meet the demands of various industries. We are a leading ASTM A312 TP 316H Welded & ERW Pipe manufacturer and supplier, offering a complete range of 316H Stainless Steel Seamless Pipe, welded pipes, and ERW pipes for high-temperature and high-pressure applications. Stainless Steel 316H is a high-carbon austenitic grade designed to deliver superior strength, excellent corrosion resistance, and enhanced creep resistance at elevated temperatures.
What is 316H Stainless Steel?
316H stainless steel is a high-carbon variant of the popular 316 grade, distinguished by its excellent strength at elevated temperatures. The “H” in 316H denotes the higher carbon content, which ranges between 0.04% and 0.10%. This increased carbon content enhances the material’s creep resistance and high-temperature strength, making it ideal for applications where these properties are crucial. Our 316H stainless steel seamless pipe and SS 316H Welded Pipes are widely used in industries such as oil & gas, petrochemicals, power plants, refineries, and chemical processing units where durability and performance are critical.
316H Stainless Steel Properties
The properties of stainless steel 316H pipe make it a highly sought-after material in various industries. Key properties include:
- High-Temperature Strength: 316H stainless steel retains its mechanical properties even at elevated temperatures, making it suitable for high-heat environments.
- Creep Resistance: The higher carbon content improves the material’s resistance to deformation under sustained high-temperature stress.
- Corrosion Resistance: Like other 316 grades, 316H stainless steel offers excellent resistance to corrosion, including pitting and crevice corrosion in chloride environments.
- Durability: The material’s robustness ensures longevity and reliability, even in harsh conditions.
- Weldability: 316H stainless steel can be easily welded using standard welding techniques, facilitating its use in various construction and fabrication applications.
- Formability: Despite its high strength, 316H stainless steel maintains good formability, allowing it to be shaped into pipes, fittings, and other components.
Benefits of Choosing 316H Stainless Steel Pipes
Opting for 316H stainless steel pipes offers numerous advantages, including:
- Enhanced Performance at High Temperatures: The material’s superior strength and stability at elevated temperatures ensure reliable performance in demanding applications.
- Long-Term Durability: The increased carbon content provides enhanced resistance to wear and tear, ensuring longevity.
- Versatility: Suitable for a wide range of industries and applications, offering flexibility in usage.
- Cost-Effective: Despite its high performance, 316H stainless steel is a cost-effective solution, reducing the need for frequent replacements and maintenance.
