7.85 g/cm³ (0.284 lb/in³) 12.5 x 10^(-6)/°C (7 x 10^(-6)/°F) 19-23% IACS (International Annealed Copper Standard) 0.27-0.30 190-210 GPa (27.5-30.5 x 10^6 psi)

IRSM 41-97 steel is known for its ability to form a protective patina on its surface when exposed to the atmosphere, similar to weathering steel. This natural rust-like patina not only provides corrosion resistance but also gives the material an attractive and weathered appearance.

Applications for IRSM 41-97 steel include:

Railway Rolling Stock: It is used in the manufacturing of railway wagons and other components due to its strength and resistance to atmospheric corrosion.

Construction: IRSM 41-97 is suitable for the construction of outdoor structures, bridges, and other architectural elements where exposure to the elements is a concern.

Poles and Light Standards: It is used for utility poles, street lighting standards, and outdoor infrastructure.

Mining Equipment: Some mining equipment and machinery components are made from IRSM 41-97 steel due to its ability to withstand harsh outdoor conditions.

Automotive Components: In some cases, it may be used for automotive components, particularly those exposed to outdoor conditions.
