300m steel
Alloy steel 300m var is similar to 4340 steel, but with the addition of vanadium element and a further increase in silicon content. This alloy steel exhibits superior toughness and ductility while maintaining high strength levels without increasing carbon content. After vacuum arc remelting, the alloy 300m var steel exhibits excellent purity. In addition, 300M steel has been awarded dual certification to the British aerospace standard BS 5155, demonstrating its superior performance and quality.
During the manufacturing process, alloy steel 300m var uses a unique heat treatment process that allows its high strength level to be maintained. At the same time, due to the addition of vanadium and the increased silicon content, its toughness and ductility have been significantly improved. The excellent properties of this alloy steel are due to its fine microstructure and excellent grain size.
Alloy steel 300m var chemical elements and properties
Alloy steel 300m var heat treated
After vacuum arc remelting, the purity of the alloy 300m var steel was significantly improved. This treatment method effectively removes impurities and gases and makes the internal structure of the steel more homogeneous. These efforts have resulted in excellent performance stability of the alloy steel at high temperatures.
In addition, 300M steel is dually certified to the British Aerospace Standard BS 5155. This certification is further proof of its superior performance and quality. This standard requires alloy steels to maintain excellent mechanical properties at high temperatures, and 300m steel successfully meets these requirements. This achievement is due to its unique composition and manufacturing process, which makes it have a wide range of applications in the aerospace field.
