The Main Disadvantages of Stainless Steel Powder Metallurgy

Gold is a high-quality hedge hedging tool, favored by investors. Especially in recent years, with the increasing instability of the world economy, gold has become one of the preferred asset allocations of investors because of its functions of hedging and fighting inflation.

Earlier, the worsening situation in Ukraine sent gold prices soaring to a two-year high of $2,070 an ounce. But gold, along with other commodities, fell back last week as conditions changed and bulls took profits, hitting a low of $1,895 an ounce. As of press time, gold was trading at $1,918 an ounce, down 7.9% from its March 8 peak. Rising gold prices may also have an impact on the Stainless Steel Powder prices.

According to China Business News, Goldman Sachs raised its gold price forecast in early March, considering Asian buyers' gold consumption demand, investment demand and central bank gold purchase demand continue to rise. Three -, six - and 12-month targets were raised to $2,300, $2,500 and $2,500 an ounce, respectively, from $1,950, $2,050 and $2,150. The last time all three accelerated was in 2010-11 when gold prices rose nearly 70%.

The World Gold Council has also noted that global gold demand is at its highest level in nearly two years, which is linked to a recovery in consumption and consumer sentiment to combat inflation. 

Compared with stainless steel produced by traditional smelting process, stainless steel powder metallurgy has the advantages of producing parts close to net shape, high dimensional accuracy, high material utilization, and uniform structure. However, it does not mean that stainless steel powder metallurgy products are perfect. Stainless steel powder metallurgy also has its disadvantages.

Most of the injection molding defects of stainless steel powder metallurgy products are in the injection molding process. Some defects of injection molding are visible to the naked eye, some may appear in the subsequent desorption or sintering process, but they can also be traced back to the injection molding process. Therefore, the quality control of stainless steel powder metallurgy products is very important.


The defects of stainless steel powder metallurgy products are generally manifested in injection molding plate defects: flashing, foaming, corrugated surface, laminar or skin, depression and surface black spot deformation are observed in appearance, low green strength, mold pasting operation. The causes and influencing factors of these defects are different, among which injection temperature and injection pressure are the key factors.


By adjusting the injection temperature and injection pressure, most defects can be solved. When the temperature and pressure are adjusted to some defects, it is the correct choice to further trace the binder system, the uniformity of powder and jointing agent mixing and refining, whether the feed is polluted, moisture absorption, humidity and other factors, and the mold cavity should be checked. Body design, gate, shunt channel and gate design are reasonable.


In the normal operation of injection molding and high-quality injection molding briquette, many influencing factors have been continuously explored and summarized in practice, accumulated experience, compared the problem with accurate analysis and judgment, and adjusted in time.
