Material Aspects of Hot Rolling and Cooling Conditions for Strips from Martensitic Steel

Article Preview

Abstract:

The paper focuses on experimental and numerical investigations of own designed, casted and then hot rolled martensitic steel. In order to understand the effect of the thermo-mechanical rolling parameters on the formation of the microstructure and resulting mechanical properties many tests and experiments have been performed. Martensitic steels offer satisfied balance of cost production, light weight and mechanical properties. These characteristics are achieved by using low alloy steel as a basis, and strict control of rolling conditions, strain rate, cooling rate and coiling temperature.
