WR 50 B steel description
WR 50 B steel is a weather resistant steel which could more accurately be termed as an "Atmospheric Corrosion Resistant Steel" and often referred to as Corten-B steel.
Weathering means that due to WR 50 B steel chemical compositions, WR 50 B steel chemical composition can increase resistance to atmospheric corrosion compared to unalloyed steels.
This is because it forms a protective layer on WR 50 B steel surface under the influence of the weather.
WR 50 B steel Deliver condition
Hot Rolled, Cold Rolled, Normalized, Quenched, Tempering, Thermal Mechanical Control Process (TMCP), Electroslag Remelting Technical, HIC test.
WR 50 B steel Application range
Due to the WR 50 B steel super property as main weathering steel, WR 50 B steel has a widely use in Mine fans, earth moving buckets, trailers and large road vehicles, drill rings, cranes, excavators, underground mining equipment, bridges and other high strength components requiring superior toughness.
