Slow cooling in the furnace <em>(10 to 20\u00b0C\/h)<\/em>. The atmosphere in the furnace must be reducing to avoid decarburization of the steel.<\/p>\n<h4>Stress relieving<\/h4>\n<p>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<h4>Austenitization<\/h4>\n<p>In order to avoid any risk of cracking it is recommended to preheat in 2 steps.<\/p>\n<ul>\n<li>1st preheating step: temperature: 450\u00b0C time: 30 s\/mm of thickness<\/li>\n<li>2nd preheating step: temperature: 875\u00b0C time: 30 s\/mm of thickness<\/li>\n<\/ul>\n<p>Recommended austenitizing temperature: 1020 &#8211; 1050\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<h4>Quenching medium<\/h4>\n<p>Oil at 80\u00b0C, vacuum <em>(pressure &gt; 6 bars)<\/em>, salt bath 500 &#8211; 550\u00b0C.<br \/>\nTo ensure good toughness, treatment with oil or salt bath is preferable.<\/p>\n<h4>Sub zero treatment<\/h4>\n<p>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<p>The temperature range from -70\u00b0C up to -120\u00b0C <em>(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 <em>(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. This treatment is optional for common applications.<\/p>\n<h4>Tempering<\/h4>\n<p>To ensure a minimum residual austenite rate as well as greater tool stability, it is essential to perform a double <em>(better triple)<\/em> tempering. Each tempering is followed by a cooling under 100\u00b0C.<\/p>\n<p>Depending on the use of the final part the following tempering temperatures are recommended:<\/p>\n<\/div>\n[\/vc_column_text]\n<table>\n<thead>\n<tr>\n<th>Austenitizing temperature<\/th>\n<th>Tempering temperature<\/th>\n<th>Hardness<\/th>\n<th>Properties<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td rowspan=\"3\">1020 \/ 1050\u00b0C<\/td>\n<td>530\u00b0C<\/td>\n<td>58 \/ 60 HRC<\/td>\n<td>Better wear resistance<\/td>\n<\/tr>\n<tr>\n<td>550\u00b0C<\/td>\n<td>56 \/ 58 HRC<\/td>\n<td>Wear and toughness<\/td>\n<\/tr>\n<tr>\n<td>560\u00b0C<\/td>\n<td>53 \/ 55 HRC<\/td>\n<td>Better toughness<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n[vc_column_text css=&#8221;&#8221; text_direction=&#8221;default&#8221;]\n<div style=\"max-width:680px\">\n<p><em>* Avoid tempering at temperatures lower than 525\u00b0C to decrease the amount of retained austenite.<\/em><\/p>\n<p>Each tempering time must be at least equal to 1h + 1h for 25 mm of thickness of the treated part <em>(equivalent thermal thickness)<\/em>.<\/p>\n<\/div>\n[\/vc_column_text][vc_column_text css=&#8221;&#8221; text_direction=&#8221;default&#8221;]\n<div style=\"max-width:680px\">\n<p><img decoding=\"async\" class=\"wp-image-4067\" src=\"https:\/\/www.tgsteels.com\/wp-content\/uploads\/2026\/10\/tpm10v-tempering-curve.png\" alt=\"TPM 10V Ultraclean tempering curve: hardness (HRC) versus tempering temperature (520 to 600 \u00b0C) after austenitizing in vacuum at 950, 1000, 1050, 1120 and 1180 \u00b0C (3 \u00b0C\/s)\" width=\"520\" height=\"518\" loading=\"lazy\" style=\"max-width:100%;height:auto\" srcset=\"https:\/\/www.tgsteels.com\/wp-content\/uploads\/2026\/10\/tpm10v-tempering-curve.png 688w, https:\/\/www.tgsteels.com\/wp-content\/uploads\/2026\/10\/tpm10v-tempering-curve-300x300.png 300w, https:\/\/www.tgsteels.com\/wp-content\/uploads\/2026\/10\/tpm10v-tempering-curve-150x150.png 150w, https:\/\/www.tgsteels.com\/wp-content\/uploads\/2026\/10\/tpm10v-tempering-curve-140x140.png 140w, https:\/\/www.tgsteels.com\/wp-content\/uploads\/2026\/10\/tpm10v-tempering-curve-100x100.png 100w, https:\/\/www.tgsteels.com\/wp-content\/uploads\/2026\/10\/tpm10v-tempering-curve-350x350.png 350w\" sizes=\"auto, (max-width: 520px) 100vw, 520px\" \/><\/p>\n<\/div>\n[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=&#8221;in_container&#8221; full_screen_row_position=&#8221;middle&#8221; column_margin=&#8221;default&#8221; column_direction=&#8221;default&#8221; column_direction_tablet=&#8221;default&#8221; column_direction_phone=&#8221;default&#8221; scene_position=&#8221;center&#8221; bottom_padding=&#8221;60&#8243; text_color=&#8221;dark&#8221; text_align=&#8221;left&#8221; row_border_radius=&#8221;none&#8221; row_border_radius_applies=&#8221;bg&#8221; overflow=&#8221;visible&#8221; overlay_strength=&#8221;0.3&#8243; gradient_direction=&#8221;left_to_right&#8221; shape_divider_position=&#8221;bottom&#8221; bg_image_animation=&#8221;none&#8221; gradient_type=&#8221;default&#8221; shape_type=&#8221;&#8221;][vc_column column_padding=&#8221;no-extra-padding&#8221; column_padding_tablet=&#8221;inherit&#8221; column_padding_phone=&#8221;inherit&#8221; column_padding_position=&#8221;all&#8221; column_element_direction_desktop=&#8221;default&#8221; column_element_spacing=&#8221;default&#8221; desktop_text_alignment=&#8221;default&#8221; tablet_text_alignment=&#8221;default&#8221; phone_text_alignment=&#8221;default&#8221; background_color_opacity=&#8221;1&#8243; background_hover_color_opacity=&#8221;1&#8243; column_backdrop_filter=&#8221;none&#8221; column_shadow=&#8221;none&#8221; column_border_radius=&#8221;none&#8221; column_link_target=&#8221;_self&#8221; column_position=&#8221;default&#8221; gradient_direction=&#8221;left_to_right&#8221; overlay_strength=&#8221;0.3&#8243; width=&#8221;1\/1&#8243; tablet_width_inherit=&#8221;default&#8221; animation_type=&#8221;default&#8221; bg_image_animation=&#8221;none&#8221; border_type=&#8221;simple&#8221; column_border_width=&#8221;none&#8221; column_border_style=&#8221;solid&#8221;][vc_column_text css=&#8221;&#8221; text_direction=&#8221;default&#8221;]\n<div style=\"max-width:680px\">\n<h3>Surface treatment<\/h3>\n<h4>Nitriding<\/h4>\n<p>TPM10V UltraClean can be nitrided at temperatures less than or equal to 20\u00b0C below tempering temperatures without risk of deterioration of the mechanical characteristics.<\/p>\n<p>Ionic nitriding at a temperature of 500\u00b0C is recommended.
