With the emergence of more and more building materials market, we have all kinds of steel pipes in our life. In order to let more small partners understand the relevant knowledge, we will briefly introduce the differences between seamless steel pipe and slotted steel pipe

Foundry enterprises need to purchase different types of scrap steel according to their own production products. Common types of casting scrap steel include Q235 scrap, punching beans, corner grooves, cold and hot rolled materials, cold rolled briquette, steel shavings, steel Scrap, pig iron filings, iron pin compacts, silicon steel sheets, etc. However, unlike steel mills, foundries have stricter requirements on the element content and “impurities” of scrap steel. First of all, the most common element content is the requirement for manganese. For example, foundries that produce high-manganese steel castings need to purchase high-manganese scrap, so as to maximize production cost savings. Another example is the foundry that produces high-grade gray cast iron, which also needs to purchase scrap steel with high manganese content. For ductile iron casting companies that produce ferrite as the matrix, scrap steel with low manganese and low chromium should be selected. In addition, some foundry companies that have requirements on the hardness of castings will specially purchase alloy scraps containing chromium, nickel, molybdenum and other elements. Secondly, casting enterprises have higher requirements for “impurities”. For scrap steel such as steel plate scraps, corner grooves, etc., foundry companies usually only choose “new materials” instead of purchasing “old...

In fact, everyone is not very familiar with the concept of precision stainless steel pipes. At this time, we need to learn. Many people are asking about the production process of precision stainless steel pipes. How many steps does a stainless steel pipe go through? Let's study hard.

Let’s start with Nickel Nickel is an extremely adaptable element and has a great range of helpful properties such as heat and corrosion resistance, electrical and magnetic capabilities as well as a low expansion level. As an added benefit, it can also be easily bonded with a number of different alloys. Nickel’s adaptability and natural properties make it a very useful metal. This has resulted in it being used to make a wide variety of nickel alloys. So, what is Nickel Alloy and Inconel? ‘Nickel alloy’ is a general term that refers to a grade of metal that has a particularly high composition of nickel within it. Inconel is simply a particular variety of nickel alloy. When you change the chemical composition of the alloy in question, this subsequently changes its benefits. Different benefits mean that different nickel alloys have different commercial uses. Some of these uses include: – Aircraft gas turbines – Steam turbine power plants – Medical applications – Nuclear power systems – Chemical and petrochemical industries Many of these applications require the material to be resistant to both corrosion and heat, hence why nickel and nickel alloys are such a good fit. Of all the nickel alloys...
