What is AISI 4140 Steel AISI 4140 alloy steel round bar sheet plate belongs to medium hardenability steel.AISI 4140 steel has high fatigue strength and low notch sensitivity. Low-temperature impact toughness is also very high, no obvious temper brittleness. AISI 4140 steel round bar is mainly used after quenching and tempering state. it is used to manufacture high-strength parts under impact loads and the fittings with large cross-sections and other stressed members. Such as the horizontal eccentric shaft of the horizontal forging machine, the crankshaft of the forging press, and etc. Its equivalent grade is JIS SCM440 and DIN 1.7225. The properties and composition of 4140 steel round bar sheet plate as below. We have been specializing in the production of 4140 alloy steel for decades, providing 4140/1.7225/SCM440 alloy round bar, square and flat steel, etc. We have our own cutting and processing facilities, rich production experience, and the specifications can be customized according to your needs Requires tailoring and customization. Over the years, we have been focusing on special steel dealers and suppliers with high-quality booths. As a professional AISI 4140 steel supplier, you are welcome to inquire at any time. specialized in Special Steel for almost 20 years. We can supply mold steel, high speed steel, alloy steel, free cutting steel and etc
