Products Description
ASTM 5140 alloy plate is a high-strength low-alloy steel composed primarily of carbon, chromium, molybdenum and manganese.It is a 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. It is used for more important tempering parts, such as parts working under alternating loads, medium speed and medium load parts.
