What is the use of 40MnB steel

Posted:2021-06-17 10:18:52

40MnB steel mainly replaces 40Cr steel to produce medium and small cross-section quenched and tempered parts, such as automobile half shafts, steering shafts, worms, spline shafts and machine tool spindles, gears, etc. In addition, it can also replace 40Cr steel to make parts with larger cross-sections such as Φ250-320mm hoist intermediate shaft. 40MnB steel can also be used instead of 40CrNi steel when making smaller parts.

40MnB uses: steering arms, steering knuckles, steering shafts, half shafts, worms, spline shafts, brake adjustment arms, etc. After quenching and tempering, 40MnB steel is used to manufacture mechanical parts that can withstand medium load and medium speed work, such as automobile Knuckles, rear half shafts, gears, shafts, worms, spline shafts, tip sleeves, etc. on machine tools.
