1.7225 Material 42CrMo4 +QT Steel Chemical Composition

Dec 14, 2019 · 42CrMo4 material (1.7225 steel) is an European standard alloy steel, the delivery condition of this steel is mostly tempered and quenched, it has high strength, high toughness, good hardenability, temper brittleness, high fatigue limit, good impact resistance after quenching and tempering, and good low temperature impact toughness. AISI P20 Steel - DIN 1.2311 - SCM4 - Songshun Steel1.2311 steel has been pre-hardened to 285-330HB (30-36HRC), which can be used directly for mold making and process. It also has the characteristics of good dimensional stability. Just Pre-hardened steel can meet the needs of the industry. The die life can reach 50W mode times.

SAE-AISI 4140 (SCM440, G41400) Cr-Mo Steel ::May 30, 2020 · Among alloy steels, the composition of SAE-AISI 4140 steel is notable for containing comparatively high amounts of chromium (Cr) and manganese (Mn). Chromium is used to improve corrosion resistance and most mechanical properties (particularly at higher temperatures). Manganese is used to improve hardenability, hot workability, and surface quality.
