    Compared to other stainless steels

    Wabash National vice president John Cannon is a fan of using 2205 duplex stainless steel in the production of tank trailers.To get more news about 2205 duplex stainless steel, you can visit stainless-steel-supplier official website.

    During the presentation “2205 Stainless Steel in the Real Tank World” at Tank Truck Week 2019 in Nashville, Tennessee, Cannon told the story of climbing into a duplex steel tank that was in a rollover accident while filled with $100,000 worth of flammable product—and still looked nearly brand new inside.

    According to the carrier hauling the load and the resulting accident report, the trailer rolled 50 feet down an embankment, taking out several trees along the way, but the 12-gauge shell did not leak or puncture, and the barrel remained fully salvageable and repairable, with no “cupping” at the rings that were impacted.

    “This carrier, just based on what they have ordered since this incident, is a believer in duplex,” he assured the audience.He and Chris Kern, the lease fleet manager at Huntsville, Texas-based tank trailer dealer The Jack Olsta Company, talked about the history of 2205, its unique chemical makeup, and the many benefits of using duplex steel in tank construction, including increased strength, and resistance to corrosive pitting and thermal shock.

    2205, which is duplex steel, meaning it’s a combination of ferritic and austenitic steel, is not a new or experimental metal.

    The earliest version was developed in Europe in the 1930s, Cannon said. New, more weldable duplex alloys, like 2205 SS, were introduced in the 1950s, and the first “significant” deployment of duplex came in the 1990s in Sentinel Transportation’s tank trailer fleet, under the direction of then-equipment manager Orville White.

    “These duplexes were created and intended to be seawater-resistant, and we all know what’s in seawater, of course, from a corrosion standpoint,” Cannon said.The metal’s corrosion resistance is the primary driver beyond its adoption today.

    Corrosion’s been a major issue for the tank trailer industry for decades. In 2002, NACE International and the Federal Highway Administration conducted a study that found the industry was spending more than $900 million a year repairing damage caused by corrosion, with most of that cost related to pitting inside tanks.
