D2 steel and O1 steel are high quality ,old steels,but they have obvious differences on chemical composition,properties and application fields.<\/p>\n\n\n\n<p>D2 is a high carbon,high chromium alloy tool steel,which contains 1.5% carbon and 11.5% chromium,and added appropriate vanadium and molybdenum.This kind of steel is known for its excellent wear resistance,high hardness and compressive strength,the hardness can reach 58-62HRC after heat treatment.D2 steel is particularly suitable for manufacturing high precision and long service life cold working steel,such as stamping dies,forming dies,cutting tools,and measuring tools.Although D2 steel is machinable in the annealed condition,and has low distortion when hardened correctly,it does not have the corrosion resistance of stainless steel. &nbsp;<\/p>\n\n\n\n<p>O1 steel is a low alloy cold working steel,and carbon is the main alloy element,with the content of about 0.95%,and also with the content of Mn,Si,Cr and other elements.O1 steel is known for its high hardness and excellent processing properties.It is easy to shape and grind,it is not easy to dull during use.However,the corrosion resistance of O1 steel is relatively low,and it need to pay attention to prevent rust during use.O1 steel is mainly used for cutting tools,woodworking tools,hardware stamping dies and forming tools.<\/p>\n\n\n\n<p>In general,the main characters D2 steel are high wear resistance and high hardness,which is more suitable for manufacturing cold working molds and cutting tools that require to bear high pressure and abrasion.O1 steel,with its excellent processing properties and moderate hardness,is more suitable for making cutting tools,woodworking tools and other occasions that require fine processing and long term sharpness.Both have their own advantages,and the choice should be made based on the specific application requirements and working environment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"

composition between D2 steel and O1 steel?<\/h4>\n\n\n\n<p>D2 is a high carbon,high chromium alloy tool steel,its main alloy elements include carbon(about 1.5%),chromium(about 11.5%),and added vanadium and molybdenum with appropriate amount. This ingredient composition makes D2 steel has excellent wear resistance,high hardness and compressive strength,<\/p>\n\n\n\n<p>O1 steel is a low alloy cold working tool steel,its main alloy elements includes carbon(about 0.95%),and also contains a certain amount of manganese,silicon,chromium and other elements.The alloy elements content of O1 steel are low,especially chromium content is much lower than D2 steel.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"what-are-the-differences-between-d2-and-o1-steel\">What are the differences between <a href=\"https:\/\/www.facebook.com\/profile.php?id=100087990137347\" target=\"_blank\" rel=\"noopener\">D2 and O1 steel<\/a>?<\/h4>\n\n\n\n<p>Hardness and wear resistance:<\/p>\n\n\n\n<p>D2 steel has very high hardness and wear resistance,the hardness after heat treatment can reach 58-62HRC,which makes it an ideal choice for making high precision and long service life cold working steel.<\/p>\n\n\n\n<p>The hardness of O1 is also high,but its slightly lower compare to D2 steel.I t also has good wear resistance which may not as good as D2 steel.<\/p>\n\n\n\n<p>Toughness and Impact resistance:<\/p>\n\n\n\n<p>The hardness of D2 steel is high,but the toughness is relatively low,it may not suitable for bearing too much impact load.<\/p>\n\n\n\n<p>O1 steel has good toughness and impact resistance,which makes it performs better in some occasions needs to bear shock loads.<\/p>\n\n\n\n<p>Processing properties:<\/p>\n\n\n\n<p>The processing properties of O1 steel is better than D2 steel,O1 steel is easy to shape and grind,it is not tend to dull during use.<\/p>\n\n\n\n<p>Although D2 steel also can be processed,it may be more different than O1 steel.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>What are the differences in application fields between D2 and O1 steel?<\/li>\n<\/ul>\n\n\n\n<p>The application fields of D2 steel:<\/p>\n\n\n\n<p>D2 steel is widely used in manufacture high precision and long service life cold working molds due to its high wear resistance and high hardness,such as stamping dies,forming dies,cutting tools and measuring tools.<\/p>\n\n\n\n<p>It is also suitable for the occasion that needs to bear high pressure and abrasion,such as punches,forming rollers,knives,scissors,cutting machines,etc.<\/p>\n\n\n\n<p>The application fields of O1 steel:<\/p>\n\n\n\n<p>O1 steel mainly applied for cutting tools,woodworking tools and other fields,which require fine processing and remain sharp for a long time.<\/p>\n\n\n\n<p>It is also suitable for fields such as metal stamping molds and forming tools,and manufacture various gauges and measuring tools.<\/p>\n\n\n\n<p>In general,D2 and O1 steel have obvious differences in chemical composition,properties,and application fields.It depends on the specific application requirement and working environment.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Welcome to My Blog!
