High Temperature and Low Temperature Strength of Explosive Weld

Abstract

Tensile and shearing tests were carried out on four kinds of explosively clad steels in order to examine these strength and ductility at various test temperatures. Four kinds of explosively clad steels are C1100/SUS304, SUS304/SM41B, SUS316/SM41B and TP28/SM41B.
Results obtained are as follows.
(1) Strength of the explosively clad steel, C1100/SUS304, at 700 K is obviously small compared to strength at 293 K. It has excellent strength and ductility at 4.2 K.
(2) Strength and ductility of the explosively clad steels, SUS304/SM41B and SUS316/SM41B at 700 K are sufficient. When the temperature becomes to 4.2 K, these strength is reduced and ductility decreases rapidly.
(3) The explosively clad steel, TP28/SM41B, has a high tensile strength at 700 K or 4.2 K and has a low shearing strength at same temperature.
