Study on the Materials for Value Seatings at High Temperature and Pressure. (1 st Report)

Abstract

Investigations were made on the thermal expansion, hardness, corrosion, acbinability, abrasion and microscopic characteristies of the following materials for the purpose of use for high temperature and pressure values.
(1) Co-Cr-W series. (2) Cost iron of Si-Mn-Ni-Cr series. (3) 13% Cr steel etc.
