DIN 17230 80MoCrV42-16 Introduce
DIN 17230 is a type of steel that is commonly used in many engineering applications. It is a low-carbon high-strength steel and is sometimes referred to as a high-tensile steel due to its excellent strength-to-weight ratio. It is made up primarily of iron, with a few other elements present in smaller amounts. The small amounts of sulfur, molybdenum, nickel, and chromium make this steel highly corrosion resistant and give it superior fatigue strength.
