AISI 310MOLN Physical Properties

SAE 310MoLN SS has exceptional resistance to high temperatures due to its high chromium content. It can withstand up to 1300°F (704°C) before it begins to experience any significant degradation in its properties. Additionally, its low carbon content prevents it from becoming brittle when exposed to very low temperatures (-200°F/-129°C). Its melting point is around 2500°F (1370°C).

AISI 310MOLN Mechanical Properties

310MoLN ss is known for being highly malleable yet still maintaining good tensile strength even at elevated temperatures such as 1300°F (704°C). Its yield strength can reach up to 70 ksi (483 MPa). Additionally, its elongation at break is 45%, which makes it well-suited for a variety of applications where stretching may be necessary.
