What are the characteristics of vacuum heat treatment of spring steel
Springs are important parts in various machines and instruments. According to their use occasions and structural shapes, they can be divided into two categories: leaf springs and coil springs. The steel used to manufacture spring parts is called spring steel. Performance requirements of s...
Do you know how to vacuum heat treat high speed steel?
High-speed steel vacuum heat treatment The superiority of high-speed steel can only be brought into play after correct vacuum hardening and vacuum tempering. Its quenching temperature is generally much higher than that of low-alloy cutting tool steel. For high-speed steel, the higher the vacuum h...
Characteristics of vacuum heat treatment of quenched and tempered steel
Quenched and tempered steel generally refers to medium carbon steel or medium carbon alloy steel used after quenching and tempering (vacuum hardening plus vacuum tempering). Performance requirements of quenched and tempered steel The working loads of many important machine parts, such as machine ...
Technology Trends in Vacuum Heat Treating
Titanium alloy has many characteristics such as strong corrosion resistance, good heat resistance, low elastic modulus, and non-magnetic. After solution treatment and aging strengthening, its specific strength is much higher than that of high-strength aluminum alloy, magnesium alloy and high-temp...
What is vacuum brazing and its advantages
For many chemical equipment manufacturers, brazing is rarely used and welding engineers do not know much about it. However, in air separation units (ASUs), vacuum brazing is often used to weld aluminum plate-fin heat exchangers. So today it is necessary to introduce to you what vacuum brazing is....
Application of vacuum brazing technology in aerospace field
Vacuum brazing technology has developed to date and has become a very promising brazing technology. Its application in the aviation field has become increasingly popular. When brazing aviation alloys such as aluminum alloys, stainless steel, high-temperature alloys, titanium, niobium, tantalum an...
Advantages and applications of vacuum heat treatment technology
Vacuum annealing Due to the degassing, degreasing and rust removal effects during vacuum heating, the gas dissolved in the metal is easily discharged, so the surface of the parts after vacuum annealing is clean and bright. During vacuum annealing, the deformed grains produced by pressure processi...
The main purpose of silicon carbide vacuum sintering furnace
Silicon carbide has extremely strong covalent bonds and still has high-strength bonding at high temperatures. Silicon carbide ceramics have relatively low density, high hardness, wear resistance, corrosion resistance, high thermal conductivity, and good thermal shock resistance. They are cost-eff...
Perfect ceramic vacuum sintering process
Vacuum sintering is sintering under vacuum conditions. Vacuum sintering has many advantages, such as promoting sintering. Compared with pressureless sintering, vacuum sintering can obtain ceramics with higher density and finer grains at lower temperatures. Another example: because there is no ga...
Carrier materials and refractory properties in vacuum furnaces
In vacuum furnaces, the refractory properties of the carrier material and furnace lining that carry the heating material are crucial. These materials must be able to withstand the harsh conditions of high temperature, vacuum or specific atmosphere, while also having good thermal stability, chemic...
