Key Features of UNS S31653 round bar:

• 316LN is a low-carbon, nitrogen-strengthened variant of Type 316, offering enhanced resistance to sensitization in high-temperature environments. • The added nitrogen content improves yield strength through solid solution strengthening, raising the alloy’s minimum mechanical property thresholds. • It exhibits excellent oxidation resistance and maintains a low scaling rate at temperatures reaching up to 1650°F (900°C). • The alloy delivers superior resistance to atmospheric corrosion and various chemical environments, making it suitable for aggressive service conditions. • Highly weldable, 316LN is regarded as one of the most fabrication-friendly austenitic stainless steels. • Hot forming operations can be carried out effectively between 1560°F and 2100°F (850–1150°C). • It is also well-suited for cold forming techniques, maintaining good formability across standard manufacturing processes.

Applications of 316LN Austenitic stainless rod:

1.Nuclear power equipment – used in reactors and piping due to high corrosion resistance. 2.Chemical industry – ideal for heat exchangers, tanks, and process pipelines. 3.Pharmaceutical and medical – suitable for clean environments and surgical tools. 4.Marine applications – resists saltwater corrosion in shafts and fasteners. 5.Cryogenic systems – maintains strength at very low temperatures. 6.Oil and gas – used in offshore platforms and high-pressure components. 7.Food and beverage processing – safe, hygienic, and corrosion-resistant.
