Physical Properties

Extended Temperature Performance

Stainless Steels are high temperature alloys and Staibar, Stairib and Staifix Hiproof have excellent mechanical performance at elevated temperature.

Tests show that on tensile testing at room temperature, after exposure to a heating regime of 600°C for 2 hours, the bars show a negligible reduction in tensile stress whilst that for conventional carbon steel shows a significant drop in value over the same temperature cycle. Austenitic stainless steels do not undergo the ductile to brittle condition change of conventional carbon steel as temperature falls.

Impact tests on notched bars show a ductile mode of failure at temperatures as low as -196°C. Austenitic stainless steel bars are therefore suitable for use in cryogenic and high temperature applications.

Low Magnetic Permeability

Austenitic grades of stainless steel have extremely low magnetic permeability characteristics and are virtually non-magnetic. This property can be very helpful to the designer of structures housing equipment such as electric arc furnaces, magnetic resonance imaging (MRI) units or other sensitive electronic equipment where a neutral magnetic environment is a requirement.

Please note, Staifix Hiproof (Duplex) is a magnetic steel.
