Study on the Materials for Value Seatings at High Temperature and Pressure. (2 nd Report)

Abstract

Investigations were made on the abrasion, galling phenomenon at high temperature and corrosion resistance of the following materials of value seatings to the solutions of 3% NaCI, HCI, H₂SO₄, HNO₃ solutions in various concentrations.
(1) Co-Cr-W series.
(2) 18% Ni-Si-Mn-Cr series cast iron.
(3) 13% Cr steel etc.
