Martensitic aging steel for additive manufacturing<\/h4>\n<\/div>\n[\/vc_column_text][vc_column_text css=”” text_direction=”default”]\n
\n

Die-casting molds often operate continuously in environments with impact loads, alternating hot and cold temperatures, or corrosion. This places high demands on the mold\u2019s overall mechanical properties, requiring not only high tensile strength but also a certain degree of toughness and ductility, especially impact toughness.<\/p>\n

18Ni 300 maraging steel is a low-carbon, high-strength steel with high hardness (> 50 HRC)<\/em>, toughness, and strength.<\/p>\n

It exhibits high dimensional stability and low deformation. It also possesses excellent machinability and maintains its properties even at temperatures reaching ~400\u00b0C, making it widely used in the manufacture of high-performance die-casting molds.<\/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=”60″ 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
