905M39 Nitriding Steel

905M39 is a chromium-aluminiummolybdenum engineering steel which is suitable for nitriding and once nitrided, offers a hard-wearing casing which is superior to EN40B. 905M39 offers an excellent overall combination of wear and abrasion resistance. With high toughness and ductility, 905M39 nitriding steel is used in the manufacture of die casting dies, clutch plates and shackle pins. 905M39 in the ‘R’ condition offers a tensile of 700-850 N/mm² whilst 905M39 in the ’S’ condition offers a tensile of 775-925 N/mm². Wear resistance after nitriding is 68HRc which is higher than EN40B
