Description

The structural steel (non-alloy high-grade steel) S250GD is deliverable with following hot-dip coatings: S250GD+Z (coating Zn), S250GD+ZF (coating Zn-Fe), S250GD+ZA (coating Zn-Al), S250GD+AZ (coating Al-Zn), S250GD+AS (coating Al-Si). The coating mass for Z amounts to 100, 140, 200, (225), 275, 350*, (450)* and (600)* g/m², for ZF to 100 and 140** g/m², for ZA to 95, 130, 185, 200, 255 and 300* g/m², for AZ it amounts to 100, 150 and 185 g/m², for AS it amounts to 60, 80, 100, (120) and (150) g/m². The parenthesis values are deliverable after arrangement the values are in each case both side minimum values (three-faced specimen). The * marked values are not deliverable for the surface types B and C and the ** marked values are not deliverable for the surface type C (see also DIN EN 10326). The advantages in opposite to the hot-dip galvanising are: - higher corrosion resistance - excellent forming behaviour - low crack susceptibility of the coating The material has a min. yield point of 250 N/mm² and is used for construction parts with high strength and high corrosion resistance. The coated steel is weldable with the usual methods. Furthermore are given the adhesive suitability and the coatability with organic materials, in each case after a previous suitable surface treatment. Application: household appliances industry, construction industry, furniture industry, electrical engineering, automotive engineering

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.
