Study on High-Temperature Mechanical Properties of SPHC Steel Produced by CSP Technology

Abstract:

The high-temperature mechanical properties of SPHC steel produced by compact strip production (CSP) process were tested on Gleeble thermal simulator under different temperature conditions. The results show that: at the strain rate of 1×10^-3s^-1,the SPHC steel has three brittleness temperature zones within the range from 650°C to 1200°C;the percentage reduction of area of the tested steel are all above 60% within the range from 950°C to 1150°C,thus the steel has good high temperature plasticity; the percentage reduction of area decreases rapidly when the testing temperature is under 900°C and the minimum percentage reduction of area is only about 41.78% at 800°C.
