ASTM 5140 Steel Plate
ASTM 5140 Steel Plate alloy structural steel is the most commonly used alloy structural steel. Its tensile strength, yield strength and hardenability are higher than that of No.40 steel, but its weldability is limited and it tends to form cracks. Is the most commonly used alloy structural steel, tensile strength, yield strength and hardenability are higher than 40 steel, but the weldability is limited, there is a tendency to form cracks. For more important conditioning and tempering Parts, such as parts working under alternating load, medium speed and medium load parts. After surface quenching, it can be used for parts with high load and wear resistance but no great impact, such as gears, sleeves, shafts, crankshafts and pins
