Quantity
The DIN W.Nr.2.4662 Screw is made of high-performance Incoloy 901 nickel-based alloy, complies with ANSI, DIN, and NF standards, and is classified as Grade A. It is available in sizes ranging from M5 to M100, with lengths from 30 to 800 mm, and an elongation rate of 12%. Designed for extreme environments, it offers high corrosion resistance and excellent high-temperature oxidation resistance, making it suitable for critical applications such as aircraft engine components and gas engines.
The DIN W.Nr.2.4662 Screw not only exhibits outstanding mechanical properties but also demonstrates exceptional oxidation resistance in high-temperature environments. At temperatures up to 800°C, the DIN W.Nr.2.4662 Screw maintains excellent oxidation resistance, primarily due to its unique chemical composition and microstructure design.
1. Oxidation Resistance Mechanism of DIN W.Nr.2.4662 Screw
The oxidation resistance of the DIN W.Nr.2.4662 Screw relies on the following aspects:
1) Role of Chromium (Cr):
The DIN W.Nr.2.4662 Screw contains approximately 12-14% chromium, which reacts with oxygen at high temperatures to form a dense Cr₂O₃ oxide layer. This oxide layer has an extremely low oxygen diffusion rate, effectively preventing further oxygen penetration into the base material and protecting it from additional oxidation.

2) Role of Nickel (Ni):
The addition of nickel enhances the alloy's stability and oxidation resistance, particularly at high temperatures. Nickel works synergistically with chromium to further improve the density and adhesion of the oxide layer.

3) Role of Titanium (Ti) and Aluminum (Al):
The inclusion of titanium and aluminum further boosts the alloy's oxidation resistance. At high temperatures, titanium and aluminum form stable oxides (such as TiO₂ and Al₂O₃), which, together with Cr₂O₃, create a composite oxide layer, further enhancing oxidation resistance.
