Annealing of 20CrMnTi Alloy Gearing steel. Slowly heated to 790-810 and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace. Different annealing ways will get different hardness.The 20CrMnTi Gearing steel will get Hardness MAX 248 HB Brinell hardness.

20CrMnTi Steel

Dec 17, 2014 · Elected by 20CrMnTi steel production of these two sets of aluminum extrusion die of cold, after 950 heated salt water quenching, tempering is not used directly, mold hardness 46 ~ 48HRC, extruded aluminum cover over 2000 pieces, still in use. 20MnCrti Steel Gear Steel Case Hardening Steel MalaysiaQuenching and temperature of 20CrMnTi gear steel; Heated slowly to 788°C, Then put in salt-bath furnace keep 1191 to 1204 quenching by oil get 60 to 66 HRc hardness. High temperature tempering:650-700cool in air, get hardness 22 to 30HRC. Low temperature tempering:150-200 Cool in ari, get 61-66HRC hardness.

Experience from 20CrMnTi - Metal and Metallurgy

Aug 29, 2009 · Next, the properties that you list are achieved by quenching and tempering 20CrMnTi. These properties would be applicable for the core. This steel would need to be case hardened if it is used in a highly loaded gear. Heat treatment question and answerAutomobile and tractor gears are made of 20CrMnTi material. The processing routes are as follows:blanking, forging, normalizing, machining, carburizing, quenching + low temperature tempering, shot peening and grinding finished products. The role of each heat treatment process is analyzed.

Learn About Quenching & Tempering Clifton Steel

Steel is strong to begin with, but sometimes its necessary to make it even stronger. One of the common treatments to achieve this is quenching and tempering. This is a process that strengthens and hardens iron-based alloys by heating, rapidly cooling, and reheating. OTAI 20CrMnMo steel alloy steel,Export to more than 20 Type :Case Hardening Steel. Introduction :20CrMnMo steel is a high strength high grade carburizing steel (case hardening steel), alsp known as 20CrMnMo alloy steel. Its strength is higher than 15crmnmo, its plasticity and toughness are slightly lower, and its hardenability and mechanical properties are higher than 20CrMnTi steel. Inquiry.
