Supply standard of nm450 wear-resistance 20mm medium plate with competitive price

This kind of steel standard of NM450 wear-resistance 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.

There are a lot of ASTM standards for pressure vessel steel plates. Such as ASTM A204, A285, A302, A387, A515, A516, A517, A537, A612, A841, etc. Those ASTM steel plates have different thickness ranges. standard of NM450 wear-resistance, ASTM A204 plates shall not thicker than 150mm. ASTM A285 plates shall not thicker than 50mm. ASTM A515 plates shall not thicker than 200mm. ASTM A517 plates and A537 plates shall not thicker than 150mm. ASTM A612 plates shall not thicker than 25mm. ASTM A841 plates shall not thicker than 100mm.
