Weathering steel is the generic name while Cor-Ten&is the United States Steel Corporations trade name for atmospheric corrosion resistant steel.As Cor-Ten&became more popular,other producing mills began to develop their own atmospheric corrosion resistant steels (AKA weathering steels).Blue Fin Condensers,Gold Fin Condensers,Microchannel Jan 17,2020·Forged of a parallel flow aluminum tubes that are mechanically fabricated to complement aluminum fins,resulting in superior heat conduction and a stunted,translucent,corrosion-resistant coil.This prototype culminates in a larger coil that is much easier to desecrate and calls for twice as much refrigerant.

COR-TEN / Weathering Steel Plate

What is CORTEN steel plate? Corten steel,also known as weathering steel or atmospheric corrosion resistant steel,often referred to by the trademark COR-TEN&steel (sometimes written as Corten steel).The name COR-TEN&refers to the two distinguishing properties of this type of steel CORrosion resistance and TENsile strength.Corten steel plate or sheet,is a type of alloy steel plate.China17-4PH Stainless Steel Manufacturers and Suppliers Stainless steel Alloy 17-4 PH is a precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions.The grade combines high strength,hardness (up to 572°F / 300°C),and corrosion resistance.Mechanical properties can be optimized with heat treatment.Very high yield strength up to 1100-1300 MPa (160-190 ksi) can be achieved.Chromate-free,environment-friendly GALVANIZEDChemical conversion coatings are also applied for high corrosion resistance,and good anti-fingerprint and lubrication charact eristics.Conforms to JIS G3313 and equivalent standards.Because the galvanized coating is thick,the finished steel sheet is particularly resistant to corrosion.Has an attractive metallic luster.
