Fine-grain structural steels Fine-grain structural steels Fine-grain structural steels

These fine-grain structural steel grades are characterised by a minimum yield strength of 275 - 460 MPa, by good weldability and high resistance to brittle cracking. Fine-grain structural steels are used above all for manufacturing vessels for pressurised gas (LPG, butane and propane tanks), pressure vessels, steam boiler parts, pressure piping, compressors etc.
Main grades of Fine-grain structural steels are :
