The Main Disadvantages of Stainless Steel Powder Metallurgy

As the world deals with potential supply shortages, oil prices are soaring again, with more dramatic spikes and sudden drops expected.

For consumers, that means more expensive gas for longer - prices at the pump remain above $4 a gallon. For the economy, that means more inflation. In addition to the pressure on consumers, any business that relies on oil -- from airlines and truck drivers to chemical companies and plastics producers -- will face higher costs.

Mr Pickering estimates that 2m to 3m barrels a day of Russian oil shipped by water are frozen out of the market with no direct buyers. Due to the soaring oil price, the price of the Stainless Steel Powder in the chemical industry will also

 be greatly affected. He said China and India are continuing to buy Russian crude. "I'm sure there will be others willing to take on more over time," he said. Mr Pickering said he did not expect oil to return to $130 a barrel, but added that it could happen. West Texas Intermediate for April settled 7% higher at $112.12 a barrel on Monday.

Francisco Branch, head of commodities and derivatives at Bank of America, said the US market was ready for cyclical price spikes and price swings in the product name.

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.

Prior to the impact of COVID-19 on the chemicals and materials industry and the price of the Stainless Steel Powder, many industry observers expected low to flat growth in 2021 in all regions outside Asia, with many countries seeing slower growth compared to recent years. Operational excellence has long been a hallmark of the chemical industry, and many companies are financially able to withstand short-term dips in end-market demand due to rapid leverage from reduced capex on hand.

The analysis shows that, whatever the final course of the pandemic, we can expect the inevitable long-term effects. Workplaces are expected to slowly return to pre-COVID-19 practices. Companies investing in enterprise-wide digital initiatives saw these "payoffs" in the early pandemic environment.

TRUNNANO provides high quality Stainless Steel Powder with reasonable price. In order to feedback to old customers, the company is still in full operations to provide Stainless Steel Powder with competitive price. said Amy Gao, sales manager of TRUNNANO. Please feel free to contact us to get the latest price.
