The DIN EN 10152 standard specifies electrolytically galvanized, cold-rolled flat steel products for cold forming, including the deep-drawing grade DC03. This standard defines the requirements for the zinc coating and the basic mechanical properties of the base material. DC03, when electrolytically galvanized in accordance with DIN EN 10152, is given an additional corrosion protection layer of zinc. This layer protects the material from oxidative influences and significantly increases the service life of the components made from it. The zinc coating can be applied in various thicknesses, depending on the specific requirements of the application. Typical coating thicknesses range from 5 to 20 µm. The chemical composition and mechanical properties of the base material DC03 remain unchanged after galvanizing and meet the requirements of DIN EN 10130. DC03 therefore retains its excellent cold formability and mechanical performance. The yield strength, tensile strength and elongation at break also remain in the same range as for ungalvanized DC03. In addition to mechanical performance, the quality of the zinc coating is of central importance. The DIN EN 10152 standard specifies the requirements for the uniformity of the coating, the adhesive strength of the zinc and the surface quality. These requirements ensure that the galvanized products offer high corrosion resistance and an aesthetically pleasing surface. The use of DC03 in accordance with DIN EN 10152 is widespread in the automotive industry, in the construction industry and in the manufacture of household appliances, where improved corrosion resistance is required in addition to high formability. Electrolytic galvanizing offers optimum protection here without impairing the excellent mechanical properties of the base material. In summary, it can be said that the deep-drawing grade DC03 offers a wide range of applications in accordance with both DIN EN 10130 and DIN EN 10152. While DIN EN 10130 focuses on high formability and surface quality, DIN EN 10152 supplements these properties with improved corrosion resistance thanks to the zinc coating. Both standards ensure that DC03 is a reliable and high-quality material for numerous industrial applications. Cold-rolled flat steel DC03, produced in accordance with the DIN EN 10130 and DIN EN 10152 standards, offers a number of advantages for applications in the cold forming process. While DIN EN 10130 defines the basic requirements for chemical composition, mechanical properties and surface quality, DIN EN 10152 extends these specifications to include specific conditions for electrolytically galvanized products that offer additional corrosion protection. Both standards together ensure that DC03 is a versatile material with high quality and durability.

Gr1 titanium pipe has plasticity. The elongation rate of the high-purity titanium pipe can reach 50-60%, and the reduction of area can reach 70-80%. Although the strength of high-purity titanium pipe is low, the pure industrial titanium contains a small amount of impurities and the addition of alloying elements can significantly strengthen its mechanical properties, making its strength comparable to high strength. This means that as long as the industrial pure titanium pipe contains a small amount of interstitial impurities and other metal impurities, it can make it have both high strength and appropriate plasticity. 2. The specific strength (strength to weight ratio) of industrial pure titanium pipe is very high in metal structural materials. Its strength is equivalent to steel, but its weight is only 57% of steel. 3. Gr1 titanium pipe has strong heat resistance, and can still maintain good strength and stability in the atmosphere at 500°C. 4. Titanium pipe also has good low temperature resistance. Even at the ultra-low temperature of -250℃, it still has high impact strength and can withstand high pressure and vibration. 5. Strong corrosion resistance, this is because it has a particularly large affinity for oxygen, and can form a dense oxide film on its surface, which can protect titanium from corrosion by the medium. Therefore, titanium has good stability in acidic, alkaline, neutral salt solutions and oxidizing media, and has better corrosion resistance than existing stainless steel and other non-ferrous metals.
