Abstract: Background: Thermal insulation materials are critical in supporting energy efficiency and safety in high-temperature applications in industries like aerospace, ceramics, metallurgy, and energy storage. Recent interest has grown in naturally occurring minerals like kaolin because they are inexpensive and have the thermal properties to significantly contribute to energy efficiency and safety. This study assesses the thermal insulating performance........

Abstract: In this research, the mechanical and tensile properties of commercially supplied SS316L stainless steel bars were studied, with comparative results reported in the literature. Specimens machined from cylindrical rods (ϕ 20 mm × 410 mm) were machined using high-speed steel tools and tested in accordance with standards ASTM E8/E8M on a servo-controlled Universal Testing Machine. The results from the tensile test revealed ultimate tensile strengths (UTS) from 601–693 MPa, yield strengths from 591–687 MPa, and an elongation of 9–12%. The range of strength values was found to be consistent with those reported in previous literature (Sharma et al., 2024, Mishra et al., 2024....
