X2CrNi12 is a stainless steel with ferritic structure, which chemical composition from 0H13, X6Cr13, 1.4006, AISI 410S deviates from the original by a small addition of Nickel, and even more limited content of Carbon. Chromium at a concentration of approx. 12% allows users to use the material as a building material in non-aggressive environments, including decorative purpose.
The other benefits of using type 1.4003 stainless steel are listed below:
1.4003 stainless steel can be used in the following scenarios:
Weldability - The fine-grained microstructure of type 1.4003 limits grain growth in the heat-affected zone (HAZ) and allows highly reliable welds in section thicknesses up to 30 mm. Ideal weld methods include GTAW, FCAW, SMAW, PAW, Spot, Laser, and Seam.
Strength and stiffness – It offers better strength, but equal structural stiffness to mild steels, such as BSEN10113 Grade Fe430A (ASTM A36). Compared to aluminium, it offers better impact and energy resistance. It acts similar to austenitic steel as it gradually yields and does not reveal a clear yield point.
Coating and painting – As stainless steel type 1.4003 provides superior corrosion resistance and exceptional abrasion resistance, it does not require coating or painting systems to be applied to enhance performance. Painting may be desired only for aesthetic reasons in some applications. The metal can resist corrosion even if the paint wears off. A clean surface free of grease and other contamination is recommended before starting the paint job. A primer coat is recommended for cold-rolled material, as it has a smoother surface. In the case of hot rolled 1D finish material a single coat of paint will suffice.
