SSAB Form Tube 420 Plus
Provides a combination of a smooth surface, improved bendability and high dimensional accuracy with a high strength steel
SSAB Form Tube 420 Plus is a precision steel tube that has over 15% higher elongation and 30% narrower tolerances compared to standard EN 10305-3/5 E420 precision tube. Additionally it has a very smooth surface, guaranteed Ra value below 0,3 µm, so it is suitable for high quality coatings, like chromium plating or high gloss painting. When selecting the optional internal trimming of the weld a lower bead, maximum 0,15 mm, can be specified.
Available in circular, rectangular, square and special shapes, the SSAB Form Tube 420 Plus is always delivered with a cold rolled (S3), scratch free surface. It is typically used in applications where weight savings are important but still formability, uniform quality and demanding tolerances are needed, for example in furniture industry or when automated manufacturing processes are used.
SSAB Form Tube 420 Plus is manufactured by cold forming and high-frequency welding from clean, high-quality, environmentally friendly steel using modern and efficient tube lines.
