Metallographic Analysis

Metallographic analysis is one of the important means of metal material testing. After the material is pre-processed by cutting and sampling, inlaying, polishing and grinding, chemical corrosion, etc., the material microstructure is observed through a metallographic microscope.

Plastic mould steel

Plastic molds include thermoplastic molds and thermosetting plastic molds. Plastic mold steel requires a certain strength, hardness, wear resistance, thermal stability and corrosion resistance and other properties. In addition, it is also required to have good manufacturability, such as small heat treatment deformation, good processing performance, good corrosion resistance, good grinding and polishing performance, good repair welding performance, high roughness, good thermal conductivity, and stable size and shape of working conditions Wait. Under normal circumstances, injection molding or extrusion mold can choose hot die steel; thermosetting forming and requiring high wear resistance, high strength mold can choose cold die steel.

Process performance of die steel

In the mold production cost, the material cost generally accounts for 10% to 20%, while the machining, heat treatment, assembly and management costs account for more than 80%, so the process performance of the mold material is one of the main factors affecting the production cost and manufacturing difficulty of the mold.

What to pay attention to when purchasing die steel

The things we need to pay attention to when purchasing different products are almost completely different. We still need to pay attention to some things at this time. In fact, this aspect still plays a very important role for us. The same is true for the purchase of die steel. What should we pay attention to when purchasing die steel? We must have a proper understanding of the market before purchasing die steel. When you have a better understanding of the overall market, you will know where you are going to purchase. It is good for us to realize the actual situation that we should pay attention to in a targeted way. This aspect is a very basic thing for us as a whole, and it is better to really find a suitable place for our procurement.

What does environmental protection bring to the steel market?

This year is the closing year of the "Ten Atmosphere". Since the beginning of the year, the Ministry of Environmental Protection has maintained an unprecedented high pressure on air pollution control in various places; however, in the first 7 months of this year, the concentration of PM2.5 in the Beijing-Tianjin-Hebei region increased year-on-year. 11.3%;PM10 concentration increased by 10% year-on-year, and there was huge pressure to meet the standards. With the acceptance date approaching, environmental protection measures continue to refine: 1, the central environmental supervision, high-level, local governments attach great importance. 2. Special supervision by the Ministry of Environmental Protection and the "2+26" special supervision of the atmosphere organized by the Ministry of Environmental Protection will last for one year from March 2017 to March 18.

Listed steel companies in the third quarter earnings more than the first half of the steel price in the future or still large fluctuations

On September 27, the research report of the iron and steel industry of Zhongtai Securities said that the single-quarter profit of most listed steel enterprises in the third quarter caught up with that in the first half of the year, of which the average gross profit per ton of steel from July to now is about 800 yuan, far exceeding that of 471 yuan in the first half of the year. The average gross profit of hot coil from July to now is about 740 yuan, about 400 yuan higher than that of the first half of the first half of the first half of the year. The most conservatively expected heating season production limits will be compressed by 8% to 9% of steel production, when the steel supply phase of the shortage can easily cause short-term steel prices large fluctuations.
