1.4435, which is a German standard urea grade austenitic stainless steel, is favored by the chemical, fertilizer and chemical fiber industries for its excellent corrosion resistance and welding performance. Following the EN 10088-1-2005 standard, this low-carbon austenitic stainless steel strictly controls the carbon content during the manufacturing process, which significantly enhances its resistance to intergranular corrosion. Its excellent welding performance is especially suitable for multi-layer welding. There is no tendency of knife edge corrosion after welding, which greatly improves the safety and service life of the equipment.

Not only that, 1.4435 stainless steel shows good corrosion resistance to common chemical media such as sulfurous acid, sulfuric acid, phosphoric acid, acetic acid, formic acid, chlorine salts, halogens, and sulfites. This makes it widely used in chemical equipment, such as containers, pipes and structural parts. Material number 1.4435, grade X2CrNiMo1812, follows DIN 17400 standard. Its unique chemical composition, including the precise ratio of carbon, silicon, manganese, phosphorus, sulfur, chromium, molybdenum and nickel, provides excellent corrosion resistance and mechanical properties. Provides a solid foundation.

In terms of mechanical properties, the tensile strength of 1.4435 stainless steel reaches σb ≥ 520Mpa, and the elongation δ ≥ 45%, showing excellent strength and ductility. It is worth mentioning that this stainless steel is based on 316L and specially developed for urea production. It strictly controls the low contents of Cr, Ni, and Mo to ensure that the stainless steel obtains a fully austenitic structure after heat treatment, while keeping the ferrite content within 0.6%. This unique design enables it to have excellent performance in the fields of high-pressure equipment linings, internal parts and corresponding pipelines for urea production.

It has a wide range of applications, and typical working conditions include urea high-pressure equipment linings, internal parts and corresponding pipelines. For supporting welding materials, you can choose AVESTA 316L-Si or AWS A5.9 ER316LSi. The supply forms are diverse, including plates, bars, flanges, welding materials, etc., which can meet the diverse needs of different customers. In general, 1.4435 stainless steel provides efficient, safe and reliable material solutions for chemical, fertilizer and chemical fiber industries with its excellent corrosion resistance, welding performance and mechanical properties.
