Chemical composition and properties of 17CrNiMo6 high strength alloy steel plate

17CrNiMo6 is the steel number of the German DIN 17210-(86) standard, the European standard is 18CrNiMo7-6, and the corresponding Chinese steel number is: 17Cr2Ni2Mo.

Compared with 20CrNiMo, the carbon content of 17CrNiMo6 steel is 0.03% lower, Cr and Ni are about 1% higher, and the other differences are not significant. The strength is at least 200Mpa higher than that of 20CrNiMo.

Chemical composition of 17CrNiMo6 high strength alloy steel plate:
Sulfur (S): ≤0.035,
Phosphorus (P): ≤0.035,
Chromium (Cr): 1.50-1.80,
Nickel (Ni): 1.40-1.70,
