BS1449 50EE steel plate for Fine-grain structural steels, normalised rolled
50EE steel plate, under BS1449 standard 50EE steel plate, under BS1449 standard, we can regard 50EE steel plate as Fine-grain structural steels, normalised rolled steels.
50EE steel plate is one mainly of Fine-grain structural steels, normalised rolled, The normalized rolled fine-grain structural steel 50EE is characterized by a minimum yield strength of 355 MPa, by good weldability and high resistance to brittle fracture, which is same with DIN:TStE355 and EN:S355NL steel.
