EN 10268 Grade H240LA skin passed introduction
H240LA, mat. No. 1.0480, is a micro alloyed steel with a min. yield strength of 240 N/mm² and a min. ultimate strain of 27%. 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
Equivalent material: ÖNORM AFM26K, SAE 037XK/XF, DIN ZStE260, DIN 1.0480, DIN ZStE 260, DIN HC260LA, AFNOR HC260LA, BS HC260LA, JIS SPFC390, EN HC260LA, EN 1.0480, GB/T CR260LA
