Stainless Steel 321H Welded Pipe Fittings Pipe Fittings

Stainless steel 321H welded pipe fittings are solid and high-grade components used in many industrial and commercial applications. These fittings resemble stainless steel 304 and 304L but feature higher carbon content for increased hardness and strength. It is an austenitic alloy composed of relatively low amounts of chromium, nickel and molybdenum, with a higher concentration of molybdenum for additional resistance to corrosion under a wide range of temperatures. The composition is low in carbon, with around 0.04% between 0–2.0% making it different from other ferritic grades like grade 430 stainless steel with higher carbon levels. Its components offer excellent corrosion resistance, creating the perfect partner for austenitic grades in harsh environments. It also features good formability and weldability with superior impact strength when heated or cooled appropriately.

Stainless Steel 321H Welded Pipe Fittings are renowned for their highly durable and corrosion-resistant properties. Their excellent mechanical strength makes them ideal for industrial environments, while their connection versatility makes them suitable for a variety of uses. They are commonly used in outdoor installations where protection from the elements is essential such as in food processing plants, dairy farms, and sewage plants. Furthermore, these fittings resist pitting corrosion, crevice corrosion and stress cracking corrosion which is an important feature when considering their use in hydrochloric acid lines. Additionally, these fittings are known to remain intact under extreme vibration conditions due to their impressive tensile strength. They, therefore, are widely used for installations involving components or equipment with higher vibrations.
