Steel Grade AISI 4140 | Richmond Steel Canada

4140 has been heat treated to reduce brittleness and relieve any stress fractures throughout the bar. This is done by heating the material just below a specific recrystallization temperature and held there for a fixed amount of time. Hot Roll Annealed. 4140 has been annealed for increased machinability, and for better cold working.Specialty Steel Co. | 4140 Steel & 4150 Steel | Specialty 4140 prehard vs annealedTypical tensile strength ranges from 114,000 PSI (Annealed Condition) up to 156,000 PSI (Pre-Hard, Quench and Tempered Condition). AISI 4140 and 4150 steels offer a high resistance to fatigue, improved toughness, impact resistance, and torsional strength.
