Ion Nitriding and Gas Nitriding

Gas Nitriding Gas nitriding has low efficiency due to the decomposition of NH3 for nitriding, so it is generally fixed to select steels suitable for nitriding, such as containing Al, Cr, Mo and other nitriding elements, otherwise the nitriding is almost impossible. Generally, JIS, SACM1, new JIS,...

Heat Treatment Anti-carburizing Copper Plating Process

Some of the heat-treated products require partial carburization, while such products require anti-seepage treatment in the non-carburized area. At present, copper plating technology is widely used for protection. The gas carburizing heat treatment temperature is 900-930°C, and the time is several...

Heat Treatment Method of Carburized parts

According to the structure of the parts, the service conditions, and the location of the process arrangement, the carburized parts can be heat treated by one of the following methods to achieve the best results. 1. Direct Quenching and Tempering Features: Can not refine the grain of steel. The qu...

Effect of Heat Treatment Process on Mechanical Properties of 20Cr14Co12Mo5 Bearing Steel

With the development of aerospace technology at home and abroad, bearing materials are facing the needs of high speed, high Hertz stress, temperature resistance, corrosion resistance and weight reduction. The requirements for various aspects of bearing materials are getting higher and higher, esp...

Analysis And Selection Of The Development Direction Of Heat Treatment

With the development of society and the advancement of science and technology, heat treatment technology is also constantly improving, so what is the development trend of heat treatment technology? Shanghai Gehang Vacuum Technology Co., Ltd., the manufacturer of vacuum heat treatment furnace, mak...

What Are The Benefits Of Vacuum Heat Treatment Technology And Why Do The Workpiece Deform？

Benefits of vacuum heat treatment technology: First, because the vacuum heating mainly relies on heat radiation at high temperature, the effect of low temperature convection is weak, so heating is slow, the temperature difference between the surface and the core of the workpiece is small, the exp...

Spring Sheet Brittleness And Heat Treatment Cracks

Spring leaf brittleness is one of the common defects of reed leaf, which can be divided into two types: heat treatment brittleness and hydrogen embrittlement after galvanizing. Microscopically, hydrogen embrittlement fractures have intergranular, dimples, secondary cracks, etc., and hair lines an...

Several Heat Treatment Characteristics Of Gear Materials

1. Hardenability Definition: Refers to the ability of steel to be quenched to obtain martensite. Different steel grades have different quenching capabilities. For steels with different hardenability, the depth of the hardened layer obtained after quenching is different, so the metallographic stru...

What To Do If You Encounter Vacuum Sudden Fire Distortion During Heat Treatment

In recent years, as the heat treatment technology of auto parts becomes more and more mature, the geometric accuracy of the workpiece after heat treatment is required to be higher and higher. Quenching deformation will inevitably cause a decrease in the geometric accuracy of the workpiece. The qu...

Partial Protection of Ion Nitriding

There are many things to pay attention to when ion nitriding of parts. Ignoring them will bring difficulties to the operation and make it impossible to proceed, or the quality of nitriding does not meet the predetermined requirements, and more seriously may cause parts and equipment to be scrappe...
