      Heat treatment<\/h3>\n

      Soft annealing<\/h4>\n

      Temperature: 820 – 850\u00b0C, duration 1h + 1h for 25 mm thickness. slow cooling in the furnace (10 to 20\u00b0C\/h)<\/em>. The atmosphere in the furnace must be reducing to avoid decarburization of the steel.<\/p>\n

      Stress relieving<\/h4>\n

      After machining, it is recommended to perform stress relieving at 650\u00b0C for a minimum of 2 hours, followed by slow cooling in the furnace to 450\u00b0C.<\/p>\n

      Austenitization<\/h4>\n

      In order to avoid any risk of cracking it is recommended to preheat in 2 steps.<\/p>\n

        \n
      • 1st preheating step: temperature: 550\u00b0C time: 30 s\/mm of thickness<\/li>\n
      • 2nd preheating step: temperature: 850\u00b0C time: 30 s\/mm of thickness<\/li>\n<\/ul>\n

        Recommended austenitizing temperature: 1030 – 1080\u00b0C. The holding time should not be too long to avoid a risk of grain coarsening and a loss of toughness. It is recommended to keep the part at the austenitizing temperature 30 minutes per inch of thickness as soon as the temperature of the surface reach the austenitization temperature.<\/p>\n

        Quenching medium<\/h4>\n

        Oil at 80\u00b0C, vacuum (pressure > 6 bars)<\/em>, salt bath 500 – 550\u00b0C.
        \nTo ensure good toughness, treatment with oil or salt bath is preferable.<\/p>\n

        Sub zero treatment<\/h4>\n

        For parts that need to have high dimensional stability and to increase wear resistance without reducing toughness, it is recommended to perform a subzero treatment at a temperature between -70\u00b0C and -190\u00b0C for 1 hour for 25 mm of thickness of the part.<\/p>\n

        The temperature range from -70\u00b0C up to -120\u00b0C (named cold treatment of steel)<\/em> leads to the complete transformation of austenite into martensite and as a consequence to better stability associated with improved hardness and better wear resistance and the temperature range from -135\u00b0C down to -190\u00b0C (named cryotreatment of steel)<\/em> leads also to the complete transformation of austenite and also the precipitation of ultrafine carbides improving a lot the wear resistance without modification of the toughness.<\/p>\n

        This treatment is optional for common applications.<\/p>\n<\/div>\n[\/vc_column_text][vc_column_text css=”” text_direction=”default”]\n

        \n

        Tempering<\/h4>\n

        To ensure a minimum residual austenite rate as well as greater tool stability, it is essential to perform a double (triple is better)<\/em> tempering. Each tempering is followed by a cooling under 100\u00b0C.<\/p>\n

        Each tempering time must be at least equal to 1h + 1h for 25 mm of thickness of the treated part (equivalent thermal thickness)<\/em>.<\/p>\n

        Hardness as a function of tempering temperature: The usual hardness for cold working uses is in the range of 58 to 61 HRC and is obtained by tempering between 450 and 500\u00b0C. Higher tempering temperature can be performed for hot work applications. In order to avoid the formation of large carbides that are detrimental to toughness, it is preferable to carry out austenitization at the lowest possible temperature, i.e. 1000 or 1020\u00b0C.<\/p>\n

        The table below shows the HRC hardness obtained as a function of the tempering temperature and the austenitization temperature.<\/p>\n<\/div>\n\n\n\n\n\n\n\n\n\n\n\n\n\n

        Fine grinding<\/h4>\n

        General indications for grinding wheels to be used on 2379 PRIME in the heat treated condition<\/p>\n

        Usually, rather soft vitrified aluminum oxide grinding wheels (grades G for plane grinding to K for cylindrical grinding)<\/em> are used.<\/p>\n

        Particular attention will be paid to effective cooling of the surface during grinding to prevent degradation of the material surface.<\/p>\n

        Electro-discharge machining<\/h4>\n

        2379 PRIME is also suitable for EDM machining (wire or electrode)<\/em>. Preferably, the machining will be carried out with a low current density and a high frequency in order to limit the thickness of the white layer as much as possible.<\/p>\n

        Then it is necessary to carry out a stress relieving at 25\u00b0C below the last tempering in order to reduce the level of residual stresses (which could lead to a risk of cracking)<\/em> and to carry out a polishing to completely remove the white layer formed during the discharge machining process.<\/p>\n

        Welding<\/h3>\n

        2379 PRIME cannot be welded.<\/p>\n<\/div>\n[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” bottom_padding=”120″ text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none” gradient_type=”default” shape_type=””][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][vc_column_text css=”” text_direction=”default”]\n
