Description

Properties: - ferritic steel with comparable corrosion properties like 1.4016 - resistant to water, steam, weak acids and brines and oxidising acids - elevated resistance to crack corrosion in hot brines and water with chloride - Ti-additives let decrease the danger of intergranular corrosion after welding - not high polishable Application: - for welded components in washing machines (base tanks) - partly in chemical constructions (weak acids), food industry, breweries, dyeing and soap industry

Equivalent Materials

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.
