Germanys cold-resistant steel grades are steel grades that resist heat, pressure, flame, and corrosion. The grades are usually used to fabricate components or products which require good tensile strength, corrosion-resistance, and oxidation-resistance. The properties of Germanys cold-resistant steel grades are determined by the grade, composition, and treatment method.
Common Germany cold-resistant steel grades include DIN 1.1191 and DIN 1.1178, both of which have high levels of tensile strength, and are suited for use in cold weather. The grades are often used to fabricate equipment that must be able to withstand high stresses in temperatures from -20°C to +800°C.
DIN 1.1191 has a high carbon content, allowing for good weldability and is resistant to wear and tear. The steel grade also has good quenching and tempering characteristics. DIN 1.1178 is made up of low carbon and chromium and is specially designed to be used in extremely cold conditions.
The mechanical properties of Germanys cold-resistant steel grades are determined by the composition and amount of alloying elements. A range of components and products can be fabricated from the grades, with the strength and toughness required for different applications depending on the grade and elements used.
The steel grades also differ in terms of welding properties. DIN 1.1191 can be welded using many common methods, however, thermal pre-treatment should be done before welding with the grade. On the other hand, DIN 1.1178 needs cautious preheat and post weld heat treatments in order to prevent the formation of brittle coarse-grained structures.
Generally, both DIN 1.1191 and DIN 1.1178 are suited for many applications, including welded cylindrical parts, springs, screws, shafts, nuts, plugs, pipe caps and other parts. Aside from construction and engineering products, Germanys cold-resistant steel grades are also widely used in the automotive and shipbuilding industries.
When compared to traditional steel grades, Germanys cold-resistant steel grades have improved levels of tensile strength and corrosion resistance. As such, components made from the steel grades can be used to produce stronger and more resilient products which are able to withstand extreme temperatures and even exposure to rain or saltspray.
By selecting Germanys cold-resistant steel grades, manufacturers and engineers are able to produce components and products which are durable and reliable, making them suitable for many industrial applications. As a result, the steel grades are in high demand amongst manufacturers, who require reliable grades which can resist wear and tear, heat, pressure, and corrosion in challenging conditions.
