Description

TRIP Steels

TRIP steels are a type of high-strength, low-alloy steel that get their name from their “TRansformation-Induced Plasticity” (TRIP) ability. This allows the steels to retain their strength and hardness at high temperatures, making them ideal for applications requiring both high strength and heat resistance. TRIP steels are also known for their good weldability, formability, and toughness.

Complex Phase Steels (CP)

The microstructure of complex phase steels is characterized by a ferritic-bainitic matrix with martensite, tempered martensite, retained austenite, and pearlite forming additional phases due to retarded recrystallization and precipitation of microalloying elements.
There is a higher yield ratio, a lower work hardenability, and a good hole expansion ratio compared to dual phase steels.
