ASK:
ANSWER: GMW3399 is the specification covers the requirements for continuous cast, hot rolled or hot rolled steel sheet with specified tensile strength from 450MPa through 1700MPa.
GMW3399 HR DP600 is hot rolled uncoated and coated steel coil or sheet , dual phase(ferrite+martensite) (DP) quality.
HR DP600 is dual phase quality steel. The delivery condition of HR DP600 steel can be common hot rolled( non coated), and Hot galvanized (coated).
“HR” means hot rolled, “580T” means min tensile strength is 580MPa, “330Y” means min yield strength is 330MPa.
The exact mechanical property requirements of HR DP600 is : Yield strength: 330-450MPa, tensile strength is Min 580 MPa, total Elongation in 80mm is min 19%, n value (4%-6%) is min 0.18, BH2 is min 30MPa
