CS4

CS4 is a cold rolled mild steel traditionally used for cold forming. Whilst the advent of newer steels have largely replaced CS4 for a lot of manufacture, it still has benefits where a close thickness tolerance is required or where stiffness is an advantage BSS hold a range of CS4 in the full hard rolled condition, typically used for the manufacture of shims and washers. CS4 is part of BS1449
