High Yield strength Steel grades are characterised by a minimum yield strength of 380 to 700 N/mm2, by good weldability and high resistance to brittle cracking.
High yield strength cold forming steel offer excellent cold- forming properties and are often used for special applications at low temperatures (below -20°C).For example for pressure vessel applications.
The main grade of High yield strength cold forming steel are :
