20CrNi2Mo Gear Steel Bar
20CrNi2Mo steel is a kind of high-quality low-carbon, because of its low content of alloy elements, various alloy elements synergistic effect is better, in the world's major industrial countries, they are listed as the recommended standard brand.
20CrNi2Mo steel can be used as a surface-enhanced carburized steel on carburizing gears, carburizing bearings and other parts; it can also be applied to such as excavator teeth (tooth decay), agricultural machinery wearing parts and other requirements after low temperature tempering Wear, impact resistant parts.
Equivalent to SAE4320 in the United States, SNCM420 in Taiwan and Japan, and 20ХН2М in the former Soviet Union, the chemical composition and some major performance indicators are the same as or similar to those of China's 20CrNi2Mo steel.
Chemical Composition:
