Poang Fasteners is a reliable manufacturer and supplier in Da Nang, Vietnam, that provides high-quality Stainless Steel 317/317L Nuts designed for challenging industrial applications. These nuts are made from an 18–20% chromium, 11–15% nickel, and 3–4% molybdenum alloy that has a low content of carbon (≤0.03% in 317L). This particular composition guarantees superior resistance to pitting, crevice corrosion, and aggressive chemical attack. The improved weldability of 317L makes it suitable for applications that need long-term integrity without carbide precipitation. Engineered for strength and durability, our 317/317L nuts provide reliable performance across chemical processing, marine, and power generation industries.

Stainless Steel 317/317L Nuts consist of iron, chromium, nickel, and molybdenum, and have better corrosion resistance than regular stainless grades. With 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, the alloy resists chloride pitting and acid corrosion. Low carbon content of 317L (≤0.03%) enhances weldability and reduces carbide precipitation. Mechanical properties are high tensile strength, good creep resistance, and better durability at elevated temperatures. These characteristics ensure that 317/317L nuts are a dependable fastening solution for industries where chemical stability, long service life, and mechanical integrity are significant.
Stainless Steel 317/317L Nuts are applied extensively in chemical and petroleum plants, where equipment that is exposed to acids, chlorides, and aggressive chemicals is held in place by them. In marine conditions, they resist saltwater corrosion and work well in adverse situations. Being corrosion-resistant to acetic, citric, and other organic acids, they are found in food processing and pharmaceutical applications. These nuts also find application in pulp and paper production, oil and gas plants, and power generation systems where long-term performance under stress is essential. Due to their tough construction and superior corrosion resistance, 317/317L nuts offer reliable fastening in intricate high-demanding environments.
