ANSWER: GMW3399 is the specification covers the requirements for continuous cast, hot rolled or cold rolled steel sheet with specified tensile strength from 450MPa through 1825MPa.
GMW3399 CR1180T/825Y-MP is cold rolled uncoated and coated steel coil or sheet , Multi- phase(MP) quality.
CR1180T/825Y-MP is Multi- phase quality steel. The delivery condition of CR1180T/825Y-MP steel can be common cold rolled( non coated), and Hot galvanized (coated).
“CR” means cold rolled, “1180T” means min tensile strength is 1180MPa, “825Y” means min yield strength is 825MPa.
The exact mechanical property requirements of CR1180T/825Y-MP is : Yield strength: 875-1150MPa, tensile strength is 1180-1350MPa, total Elongation in 80mm is min 5.0%, Bending radius longitudinal and transverse is min 3.5t
