Characteristic and application of Fine-grain Structural Steel
Fine-grain Structural Steel grades are characterised by a minimum yield strength of 275 - 460 MPa, with good weldability and high resistance to brittle cracking.
Fine-grain structural steels are used for manufacturing vessels for pressurised gas, pressure vessels, steam boiler parts, pressure piping, compressors etc.
Delivery condition of Fine-grain Structural Steel
Normalize, annealing,tempering,TMCP,PWHT, impact test,Q&T, etc.
