High-temperature strengths and corrosion resistances of porous materials made from granulated Cr and Cr-30 Ni powders

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

  1. 1.

    Porous material of granulated Cr-30Ni powder has a higher strength at low and high temperatures than materials of pure Cr and at high temperatures its strength is virtually equal to that of Kh23N18 heatresisting steel (with the same porosity).

  2. 2.

    Porous material of Cr-30Ni has a higher corrosion resistance in liquid aggressive media than material of pure Cr and is also resistant in HNO3 and H2SO4 solutions.

  3. 3.

    Porous material of granulated Cr-30Ni powders has a higher cinder resistance at 1373°K than Cr, Ni, and Kh23N18 stainless steel.

  4. 4.

    From their study of the properties of porous material made from coarse Cr-30Ni powder, the authors recommend its use as a permeable material in high-temperature oxidizing gases.
