Tool Steel Grades Definition System

According to the different chemical composition, tool steels can be divided into carbon tool steels, alloy tool steels and high speed steels (high alloy tool steels). Alloy Tool steel (here referred tool steel) is a type of carbon and alloy steel that is well-matched for tool manufacturing because of its hardness, resistance to abrasion and […]

What’re the main properties of hot work tool steel?

  Hot work tool steel is the high alloyed Cr-Mo-V tool steel which used for the non-cutting forming of workpieces made of iron and alloys at high temperatures. They are applied in processing such as hot forging dies, extrusion, drop forging as well as tube and glass products manufacturing. In recent years, in order to […]

It characterized good corrosion performance excellent welding performance, is widely used in industry and components like chemical processing, paper manufacturing, desalination equipment, firewalls, bridges, pressure vessels, heat exchangers, turbine blades and transmission shafts of offshore systems. The higher content of chromium, molybdenum […]

What’s the difference between brass and bronze?

  In the last article, we discussed “what’s the admiralty brass”, today let us take the “brass” on the table. As the two of frequently used of copper alloy, they indeed have various of similarities more than the literalness, sometimes brass and bronze are a source of confusion and people often mix them up, Can you […]

What’s admiralty brass?

  Brass is a Copper-zinc alloy with the addition of alloying elements such as Tin, Arsenic, Manganese, Aluminum, Silicon and Lead, which are usually less than 5 %. Theses addition elements enhance the whole alloy properties, making the material is ideal for specific application areas. There are over 40 standard grades of brass with zinc […]

4 commonly used welding methods for titanium alloy

  Titanium offers an amazing corrosion resistance but is two times lighter than steel. Titanium also has a very high tendency to oxidize at higher temperatures. It extremely important to keep the molten metal away from atmospheric air while welding because even very little contamination of oxygen will lead to porosity. With the wide application […]

Application of titanium alloy in aviation industry

  In the 1950s, the United States developed firstly the titanium alloy Ti-13V-11Cr-3Al in high-speed awacs, making this light-weight, high-strength, heat-treatable alloy was used for flight. In the 1960s, titanium alloy was widely used in non-military aviation engines and wide-body jets such as Boeing 747s. In the 1970s, the application of titanium alloy in aviation […]

2205 duplex stainless steel welding analysis

  Composed by close to 1:1 Ferrite and Austenite phase, duplex stainless steel has excellent mechanical properties and resistance to chloride stress corrosion performance, was widely used in the oil and gas pipelines, chemical transportation tank, and the shipbuilding industry. Duplex stainless steel has excellent weldability and during the welding process, the microstructure of welding joint, especially the thermal zone, will […]

A brief introduction of two-sides titanium clad plate

  Clad titanium plate refers to the composite plates made by cladding titanium plate and base steel plate through the explosion and rolling process. The base metal usually uses some cheaper material such as carbon steel or low alloy steel plate and the cladding layer usually using the stainless steel plate and other alloy steel […]

A brief introduction of heat treatment for titanium and titanium alloy

  Titanium and titanium alloy has a perfect strength and weight ratio, good toughness and corrosion resistance. Titanium alloy is mainly used for manufacturing aircraft engine compressor parts and structural parts of missile and high-speed aircraft. In the mid-1960s, titanium and its alloys were used in the general industry to make electrodes for the electrolytic industry, condensers for power stations, heaters for […]
