Type 321 stainless steel is an austenitic steel, mirroring many of the properties of Type 304 but enhanced with increased titanium and carbon content. This unique composition grants metal fabricators superior corrosion and oxidation resistance, coupled with exceptional toughness even in cryogenic conditions. The titanium in 321 stainless steel provides various distinct advantages: it prevents harmful carbide precipitation in the heat-affected zone (HAZ) of the weld, offers protection against intergranular corrosion, and reduces embrittlement in high-risk areas of the weld. Predominantly used in environments where parts are heated to carbide precipitation temperatures (800°F-1500°F) and exposed to corrosive atmospheres, 321 stainless steel maintains its integrity. Unlike 304 stainless steel, 321 contains more nickel and is stabilized with titanium. This element interacts preferentially with the carbon in the steel, averting the formation of chromium carbides at grain boundaries, thereby preserving corrosion resistance by minimizing chromium consumption near the grain borders during exposure to critical temperatures. The grade hardens efficiently with cold working, is easily weldable, and typically does not require post-weld annealing to maintain its superior performance across diverse corrosive conditions.

Stainless Steel Welded Tubes

Stainless steel tubular products, crafted from premium stainless steel strip, are roll-formed and fusion-welded along the longitudinal seam. Our cutting-edge welding process at Daxun ensures no filler metal is used during welding, ensuring a seamless finish.

Quick response

• Good formability and weldability
• Operates efficiently at temperatures up to 900°C
• Resistant to acids, alkalis, and low temperatures
• Excels in response to cold work hardening
• Outstanding welding characteristics
• Superior corrosion resistance
• High creep and stress rupture properties. Grade: AISI 321/321H-S32100.

 

Stainless Steel Drawn Tube

Our high-quality stainless steel tubular products are initially rolled and then meticulously re-drawn to the final size. This rolling and drawing process is ideal for producing thick-walled, large-diameter tubes that cannot be rolled directly to size but offer significant cost savings over seamless tubes. All our stainless steel drawn tubes undergo bright annealing for a flawless finish.
