Description
X3CrNiMo13-4 Round Bars / 1.4313 Round Bars
X3CrNiMo13-4 Round Bars / 1.4313 is a Low-Carbon Martensitic Stainless Steel Containing Chromium, Nickel and Molybdenum. Our X3CrNiMo13-4 Round Bars are available in different diameters, lengths and surface finishes to suit machining, fabrication and engineering requirements.
1.4313 is corrosion resistant, soft martensitic chrome-nickel steel with molybdenum addition. Very good strength and toughness properties. 1.4313 heat treated according to the following three different heat thereatment contitions: QT650, QT780, QT900. The numbers 650, 780 and 900 are showing the minimum tensile MPA strenght of the materials.
M/s Textron Steel and Alloys Stock & Supplies X3CrNiMo13-4 Round Bar, also known as EN 1.4313 stainless steel round bar, for demanding industrial applications requiring a combination of strength, toughness and corrosion resistance.
