Understanding the Composition and Characteristics of 16Mo3KW Steel Grade

[ad_1] The 16Mo3KW steel grade is a low alloy steel with a composition that includes chromium and molybdenum. Its chemical composition typically includes:

– Carbon (C): 0.12-0.20%
– Manganese (Mn): 0.40-0.90%
– Silicon (Si): 0.25-0.35%
– Phosphorus (P): 0.025% max
– Sulfur (S): 0.010% max
– Chromium (Cr): 0.30-0.60%
– Molybdenum (Mo): 0.25-0.35%

The addition of chromium and molybdenum helps improve the steel’s strength, heat resistance, and corrosion resistance. This makes 16Mo3KW suitable for use in high-temperature and pressure applications, such as in the manufacturing of boilers and pressure vessels.

In terms of mechanical properties, 16Mo3KW steel typically has a tensile strength of 450-600 MPa and a yield strength of 280-430 MPa. Its elongation at break is around 22% and its impact energy value is about 40J at -20°C.

Overall, the 16Mo3KW steel grade is known for its good weldability and formability, as well as its high temperature and corrosion resistance properties. It is important to note that the actual properties of 16Mo3KW steel may vary depending on the manufacturing process and heat treatment it undergoes.
