Description

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
