Weathering steel - Material DB - RoHS - Reach

Weatheringrefers to the chemical composition of these steels, allowing them to exhibit increased resistance to atmospheric corrosion compared to other steels. This is because the steel forms a protective layer on its surface under the influence of the weather. The corrosion-retarding effect of the protective layer is produced by the particular distribution and concentration of alloying elements in it. The layer protecti…Weathering steel is popularly used in outdoor sculptures, such as in the large Chicago Picasso sculpture, which stands in the plaza of the Daley Center Courthouse in Chicago, which is also constructed of the same weathering steel and as exterior facades, for its rustic antique appearance. Examples include Barclays Center, Brooklyn, New York, The Angel of the North, Gateshead, UK and the Humanities and Arts complex at Leeds Metropolitan University – Broad…See more on Steel - Material DB - RoHS - ReachThe noun steel originates from the Proto-Germanic adjective stahliją or stakhlijan (made of steel), which is related to stahlaz or stahliją(standing firm). The carbon content of steel is between 0.002% and 2.1% by weight for plain iron–carbon alloys. These values vary depending on alloying elements such as manganese, chromium, nickel, iron, tungsten, carbon and so on. Basically, steel is an iron-carbon alloy that does not undergo eutectic reaction. In contrast, cast iron does …See more on Is galvanized steel RoHS compliant?Manufacturers are now often asked to supply RoHS compliant materials for end products that are not related or linked to electrical or electronic equipment in any way. In fact, most hot-dip galvanized steel products should be exempt from the RoHS directive due to the nature of the products that are produced by the industry and their end use.See all results for this What is the corrosion resistance of weathering steel?The enhanced corrosion resistance of weathering steel in relation to mild steel or plain C steel is due to the formation in low aggressive atmospheres of a compact and well‐adhering corrosion product layer known as patina.See all results for this question

What is the new information on RoHS and reach?

There has not been a lot of new information on the European legislation, Restriction of Hazardous Substances (RoHS), and the European chemical policy, Registration, Evaluation, and Authorization of Chemicals (REACH), since this was discussed several years ago.See all results for this What is Weathering Steel (WS)?Weathering steel (WS), also known as low‐alloy steel, are steels with a carbon content of less than 0.2 wt. % to which mainly Cu, Cr, Ni, P, Si and Mn are added as alloying elements to a total of no more than 3‐5 wt. % [1].See all results for this Stainless steel - Material DB - RoHS - ReachOxidation
High oxidation resistance in air at ambient temperature is normally achieved with addition of a minimum of 13% (by weight) chromium, and up to 26% is used for harsh environments. The chromium forms a passivation layer of chromium(III) oxide (Cr2O3) when exposed to oxygen. T…Acids
Stainless steel is generally highly resistant to attack from acids, but this quality depends on the kind and concentration of the acid, the surrounding temperature, and the type of steel. Type 904 is resistant to sulfuric acid at room temperature, even in high concentrations; types 316 and 317 a…Bases

W-grade steel is essentially high carbon plain-carbon steel. This group of tool steel is the most commonly used tool steel because of its low cost compared to others. They work well for small parts and applications where high temperatures are not encountered; above 150 °C (302 °F) it begins to soften to a noticeable degree. Its hardenabilityis low, so W-group tool steels must be …See more on
