2020 Steel Price Forecast General Steel

An October 2018 release from the World Steel Association predicted a small increase (1.4%) in global steel demand for 2019. That projection proved to be too conservative as the same report (pictured above) in October 2019 details increases of 3.9 percent due in large part to an unexpected rise in demand in China.. The year was challenging for the vast majority of worldwide economies, but

4 Types of Metal That Are Corrosion Resistant or Don't Rust

Oct 03, 2018 · Stainless steel types, such as 304 or 316, are a mix of elements, and most contain some amount of iron, which easily oxidizes to form rust. But many stainless steel alloys also contain a high percentage of chromium at least 18 percent which is even more reactive than iron. 6 steps to successful brazing - The FABRICATORBecause most brazing fluxes are corrosive, cleaning is essential. Cleaning usually is a two-step operation:Remove the flux residues. Remove any oxide scale formed during the brazing process by pickling. Because most brazing fluxes are water-soluble, you can remove residues by quenching the assembly in hot water (120 degrees F or hotter).

Types of Galvanizing and other Zinc Coatings

Zinc coatings are applied to steel surfaces by hot dip galvanizing, electroplating, sherardising, mechanical plating, painting with zinc-rich coatings and zinc spraying (metallising). Of these, the HDG process is by far the most widely used. Following is a brief explanation of each type of zinc coating. Hot Dip Galvanized Steel Pipe, Galvanized PipeHot-dip galvanizing (HDG), as referenced is the process of dipping fabricated steel into a kettle or vat of molten zinc. While the steel is in the kettle, the iron metallurgically reacts with the molten zinc to form a tightly-bonded alloy coating that provides superior corrosion protection to the steel.

HOT DIP GALVANIZED STEEL, known as ZINCGRIP® Steel, is continuously coated on both sides with a zinc coating. The hot dip process, pioneered by AK Steel, provides a tight metallurgical bond between the steel and the coating. This process results in a material with the strength and formability of steel plus the corrosion protection of zinc.
