Standard – thin sheet metal DC01 (EN10139 \/ 1.0330) <\/strong><\/h4>\n\n

DC01<\/strong> is a cold-rolled thin sheet in a thickness range of 0.5 \u2013 3.0 mm. This material is used for general applications in place of S235JR (see entry below) for thicknesses up to 3mm. Surface: stained, greased.<\/p>\n\n

Structural steel S235JR<\/strong> (ST 37-2 \/ 1.0038) with scaled surface<\/h4>\n\n

S235JR:<\/strong> Hot-rolled, unalloyed, low-cost standard structural steel with a decorative scaled surface for general applications. Rust protection is required outdoors. Note:<\/strong> Each sheet has an individual color structure and may have traces of transport and handling – there is therefore no guarantee for a specific appearance.<\/p>\n\n

CorTen A (S355J2WP \/ 1.8946) und CorTen B (S355J2W \/ 1.8965) <\/h4>\n\n

CorTen A and B<\/strong>\u00a0are structural steels with very good resistance to corrosion. CorTen stands for \u201cCORosion resistance\u201d and \u201cTENsile strength\u201d. Weathering forms a durable barrier layer that protects against further corrosion. The characteristic rust-brown patina is created. The steel is used outdoors for sculptures, architecture and horticulture without additional rust protection.<\/p>\n\n

CorTen A<\/strong> (S355J2WP \/ 1.8946), phosphorus alloyed, even more weatherproof than CorTen B, but harder to form.<\/p>\n\n

Structural steels can be recognized by the letter S for \u201cstructural steel\u201d. This is followed by the minimum value of the yield point in N \/ mm\u00b2, specified for the smallest product thickness. The leading letter D indicates sheets made of soft steels for cold forming, a C as the second letter stands for cold rolled. <\/p>\n\n

Steel is the most important metallic material. Steel consists mainly of iron, but the other components have a major influence on the material properties. The iron is always accompanied by a certain amount of carbon. As the content rises, the material becomes more brittle. From a carbon content of 2%, one no longer speaks of steel, but of cast iron. Alloying, especially with chromium, nickel, molybdenum, manganese, and vanadium, allows the material properties to be changed within wide limits. Higher alloy steels, such as rustproof grades, can be found under the entry stainless steel. <\/p>\n\n
