SCM415 is a low carbon alloy steel designated by the Japanese Industrial Standard (JIS), which is comparable to the domestic 15CrMo steel grade as well as the ISO standard 15CrMo4. As a high-performance alloy structural steel, SCM415 is widely used in many industrial fields due to its unique chemical composition and mechanical properties. In this article, we will introduce the chemical composition, mechanical properties, heat treatment process, application areas and market supply of SCM415 in detail.
SCM415 chemical composition
The main chemical composition of SCM415 steel includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), chromium (Cr) and molybdenum (Mo). Specifically, the chemical composition ranges are as follows:
* Carbon (C): 0.13 ~ 0.18%
* Silicon (Si): 0.15~0.35%
* Manganese (Mn): 0.60~0.85% (upper limit up to 0.90% in some sources)
* Phosphorus (P): ≤ 0.03%
* Sulphur (S): ≤0.03%
* Chromium (Cr): 0.9~1.2%
* Molybdenum (Mo): 0.15\~0.3% (upper limit of 0.25% in some data)
