What is the application of alloy structural steel materials containing Mn and B

15MnVB alloy structural steel: Used for manufacturing small and medium carburized parts, such as tooth shaft, shaft, etc.

20MnVB alloy steel: It can be used to manufacture small and medium carburized parts with large modulus and heavy load, such as gears and shafts, which can replace 20CrMnTi and 20Cr steel.

40MnVB structural steel: It can replace 40Cr steel or part of 40CrMo and 40CrNi steel to make important quenched and tempered structural parts.

20MnTiB alloy structural steel: It can be used to manufacture carburized gears and other parts with large size and medium load, which can replace 20CrMnTi steel.

25MnTiBRE steel material: Replace 20CrMnTi, 22CrMnMo and 20CrMo steel to make medium load gears.

20SiMnVB steel: It can be used to make sliding gear, gear ring, gear shaft, etc. of tractor, which can replace 20CrMnTi steel.
