Where can buy the 20mm thickness NM450 steel grade

This kind of steel NM450 steel grade is generally used in the quenched and tempered state, and can also be used in the normalized state, and is suitable for manufacturing parts that work under higher stress and wear conditions. When the diameter of the workpiece is less than 60mm, the performance of 45mn2 structural steel is equivalent to that of 40Cr steel. 45mn2 structural steel is used in parts under higher stress and wear conditions, such as universal joint shafts, axles, connecting rod covers, friction discs, worms, gears, gear shafts and other quenched and tempered or normalized parts.

NM450 steel grade, SS400 steel is one of the most commonly used hot rolled general structural steel. SS400 steel’s mechanical properties is yield strength more than 225-235MPa, tensile strength 360-510Mpa and 340-470Mpa. For SS400 steel, the C element content is 0.2% max, the Mn element content is 1.40% max, the P element content is 0.045% max, the S element content is 0.045% max.
