30crnimo8 qt

30crnimo8 steel is a tempered steel, also known as alloy steel. It consists of the following components: 0.26%-0.34% carbon (C), 0.40%-0.70% silicon (Si), 0.50%-0.80% manganese (Mn), 1.80%-2.20% nickel (Ni), 0.80%-1.10% molybdenum (Mo), 0.020%-0.035% sulfur (S), 0.015%-0.040% phosphorus (P), and residual chromium (Cr).

30crnimo8 qt steel has excellent strength and toughness and is suitable for high strength and high stress applications. It has good fatigue resistance and high wear resistance. Therefore, it is often used to manufacture parts that require higher strength and toughness, such as bearings, retarders, gears, motor vehicle parts and drive shafts.

30crnimo8 qt material properties

Application:
Alloyed heat treatable steel round bar 30crnimo8 qt with a typical tensile strength of 1100 -1300 N/mUsed for highly stressed components, where the combination of high strength with tenaciousness is of utmost importance. High cold formability: Parts of different shape can be manufactured, a favorable fibering for stress, a very good surface condition and an high dimensional accuracy. When cold formed the smooth surface leads to an increased fatigue and vibratory strength.
