Description

The material X17CrNi16-2, mat. no. 1.4057, is used acc. DIN 17440 : 1996-09 for rods (for pressure vessels), forgings and drawn wire. For the application acc. DIN 17440 : 1985-07 (X 20 CrNi 17 2) resp. acc. DIN EN 10088-1,-2,-3 : 1995-08 (X17CrNi16-2) applies: The quench and temperable grade (17 % Cr) is good resistant to weak lyes and acids, stronger oxidising acids (e.g. nitric acid), water and steam. It is used for high loaded machine parts like pumps and compressors, ship building, food and cosemtic and acetic acid industry. The steel has good running properties and a good wear resistance and is high polishable. Sliding between parts with different conditions should be avoided because of seizing.

This material data has been provided by WIAM.

"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.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
