MIR50 NON-GALLING, HIGH STRENGTH STAINLESS STEEL
High Degree of Corrosion Resistance – Similar to type 316 stainless. Hardened “PH” Custom Stainless Alloy.
Elevated Strength Levels – Hardness as delivered Rockwell “C” 26/33. Typical tensile strength is approx. 140,000 PSI @ 28Rc. Can be hardened to Rockwell “C” 36/44 with very little loss in corrosion resistance.
Non-Galling – Compatible with most stainless, carbon and alloy grades of steel.
Ease of Machining – Engineered for ease of machining. Less induced stress and movement. No detrimental additives, such as sulfur and selenium.
Low Carbon Levels – (.05)
Low Degree of Memory – Low degree of retained stress. Very little movement during machining or in service.
High Degree of Wear Resistance – Can be safely hardened to wear plate levels of
Welds Easily – (see welding data).
Excellent Chemistry – Elevated nickel content with additions of Molybdenum, Columbium and Tantalum for corrosion resistance, strength and toughness.
Charpy “V” Notch Impact – approx. 120 ft/lbs @ 70°F (Rockwell “C” 28)
Stress Corrosion Test – 1% NaCl+.5% Acetic Acid + H/2S @ Rockwell “C” 33 w/ 60,000 PSI applied stress – no findings after 500 hours.
