EN 10268 Grade H400LA skin passed introduction
H400LA, mat. No. 1.0556, is a micro alloyed steel with a min. yield strength of 400 N/mm² and a min. ultimate strain of 18 %. The material is well cold formable. The mandrel diameter at bending test 180° amounts to 0,5e for transverse test specimen (e= nominal thickness).
Thin sheets made of micro alloyed high-tensile steel allow for a steel thickness reduction and therewith a building weight reduction for special application purposes.
Application: car manufacturing, construction trade, household appliances industry, plant construction etc.
The material is suitable for metallization by hot-dip coating, application of electrolytic coatings and/or of organic or other coating.
Welding:
The material is suitable for:
- MAG (metal-active-gas)
- plasma welding
- laser welding
- compression weld welding
- resistance welding (spot, roll weld, buckle welding)
- arc hand welding
