Product Description

Weatherproof BoardWeather-Resistant Structural Steel Is Atmospheric Corrosion-Resistant Steel, Which Belongs To Low-Alloy High-Strength Structural Steel. According To Its Main Characteristics, It Is Divided Into High-Weather-Resistant Structural Steel And Weather-Resistant Steel For Welded Structures.High Weathering SteelHigh Weather Resistance Structural Steel Is To Add A Small Amount Of Copper, Phosphorus, Chromium And Nickel Elements To The Steel To Form A Protective Layer On The Collective Surface Of The Metal To Improve The Atmospheric Corrosion Resistance Of The Steel. A Small Amount Of Molybdenum, Niobium, Vanadium, Titanium, Zirconium And Other Elements To Refine The Grain, Improve The Mechanical Properties Of Steel, Improve The Strength And Toughness Of Steel, Reduce The Brittle Transition Temperature, So That It Has Better Resistance To Brittle FractureWhy Can Weathering Steel Rust But Not Rot?Weathering Steel Is Different From Ordinary Steel, And At The Beginning, It Will Also Rust On The Surface Like Ordinary Steel. This Process Is Even Faster Than Normal Steel Due To Its Higher Alloying Degree. However, Due To The More Complex Lattice Inside The Weathering Steel, A Dark Black Dense Rust Layer Will Grow Under The Loose Rust On The Surface. In This Dense Rust Layer, Nickel Atoms Replace Part Of The Positions Of Iron Atoms, Which Makes The Rust Layer Have Cation Selectivity And Resists The Penetration Of Corrosive Anions.It Is This Dense Rust Layer That Makes Weathering Steel Rust On The Surface, But The Interior Will Not Continue To Be Rusted. In Fact, As Long As You Distinguish Carefully, You Can See That The Surface Of Weathering Steel Is Different From Ordinary Rust: The Rust Of Weathering Steel Is Uniform And Dense, And It Is Close To The Surface Of The Steel To Protect The Steel; While The Rust Is Mottled, Loose And Porous. If You Touch It, It Will Fall Off.
