Vacuum Hardening of Slender Parts
1. Selection of Process Parameters Vacuum quenched parts have less deformation, but it must be based on the selection of correct process parameters. For example, the conventional quenching temperature of 9Cr18 steel is 1050~1080°C, and the hardness after quenching is >58HRC. Although it can me...
What is the Difference Between Sintered NdFeB Magnet and Bonding NdFeB?
NdFeB magnets can be divided into two types: bonded NdFeB and sintered NdFeB. The difference between the two is mainly in the process. Bonding NdFeB is made by adding NdFeB magnetic powder to the binder. Bonding is actually injection molding, while sintering is vacuumed and heated at high tempera...
Integrated Process of Vacuum Brazing and Heat Treatment of Martens Stainless Steel
The base material used in the test is X12Cr13. X12Cr13 is a martensitic stainless steel. This steel has a relatively low carbon content and is mostly used for structural parts that require a certain strength and toughness. It is quenched and tempered during use to improve its comprehensive mechan...
Effect of Vacuum Heat Treatment of 20Cr13 Stainless Steel on Corrosion and Wear Resistance
1. 2Cr13 Material Properties 2Cr13 is a stainless steel with magnetic properties, good hardness, welding should be preheated. The austenitic stainless steel electrode used for welding with Q235 does not need to be preheated, and the welding uses a smaller current. 2Cr13 welding consumables can be...
Vacuum Distillation Technology in the Purification of Rare Earth Metals
1. Vacuum Technology Used in the Purification of Rare Earth Metals As we all know, rare earths have made a significant contribution to the economic growth of countries around the world. They have many special functions. They are the basic raw materials for new functional materials such as rare ea...
Application of Vacuum Sintering Technology in Diamond Tool Manufacturing
Vacuum sintering technology is used in the manufacture of diamond tools, which can reduce the consumption of high temperature resistant molds and reduce the cost of tools. It is suitable for the production of different batches of products, especially in the manufacture of large-scale and complex-...
Application of Vacuum Annealing Furnace in Annealing of Titanium and Titanium Alloys
In recent years, rare metal materials, especially titanium and titanium alloys, have been widely used in aerospace, navigation, nuclear power, petrochemical and other fields. These industries have extremely high requirements for the quality of titanium materials. Vacuum annealing is the intermedi...
Titanium Alloy Ion Nitriding
At room temperature, titanium alloys have three matrix structures, and titanium alloys are divided into the following three categories: α alloys, (α+β) alloys and β alloys. China is represented by TA, TC, and TB respectively. Alpha titanium alloy: stable structure, higher wear resistance than pur...
Application of Vacuum Heat Treatment Technology in Forging Industry
As an advanced heat treatment production technology, vacuum heat treatment technology has a development history of more than 40 years in my country. It is widely used in various materials and has many advantages such as no oxidation, good surface quality, small deformation, and no pollution. This...
Solution Treatment of Alloy, Vacuum Tempering and Recrystallization of Non-ferrous Metals
Vacuum tempering furnace is mainly used for vacuum tempering of tool steel, die steel, high-speed steel, ultra-high-strength steel, titanium alloy and other materials after vacuum quenching, solution treatment, recrystallization annealing and vacuum aging of non-ferrous metals. So what should be ...
