UNS S31008 Cold Rolled Pipes
S31008 steel pipe is a high-temperature corrosion-resistant steel suitable for industrial applications in high-temperature environments. The cold rolling and hot rolling processes of S31008 require strict control of temperature, speed and other parameters to ensure the performance and dimensional stability of the finished material.
S31008 heat-resistant stainless steel pipe has good thermal expansion and contraction properties and can maintain dimensional stability in environments with large temperature changes. The domestic and foreign standard grades corresponding to S31008 are: UNS S31008; EN 1.4845; JIS SUS310S; 0Cr25Ni20. The relatively low density of S31008 gives it certain advantages in lightweight design and energy saving.
UNS S31008 Stainless Steel Hot Rolled Pipes have good fatigue resistance and are suitable for applications where they are subject to cyclic deformation and loading. The chemical composition is: C: ≤ 0.08, Si: ≤ 1.50, Mn: ≤ 2.00, P: ≤ 0.045, S: ≤ 0.030, Cr: 24.00-26.00, Ni: 19.00-22.00. The fatigue performance of S31008 is affected by factors such as material structure, stress state, and working environment. The fatigue life can be improved by optimizing the process.
