EN 10268 Grade H320LA skin passed introduction
H320LA, mat. No. 1.0548, is a micro alloyed steel with a min. yield strength of 320 N/mm² and a min. ultimate strain of 22 %. The material is well cold formable. The mandrel diameter at bending test min. 180° amounts to 0e 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
