Grade 143D Stainless Steel
Description
1.4594 (X5CrNiMoCuNb14-5) is a precipitation hardened martensitic stainless steel used predominantly in the aerospace industry. It offers excellent strength and hardness combined with a good general corrosion resistance (similar to that of the 300 series stainless). It also offers excellent anti-galling properties and a good resistance to some mildly acidic conditions. However, 143D is subject to pitting corrosion in marine environments and crevice corrosion on prolonged immersion. It shows the following features and properties:
Excellent strength and hardness levels
Good general corrosion resistanceThis material data has been provided by Matmatch.
"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
