35SiMn alloy structural steel
35SiMn steel is a kind of high-quality alloy structural steel. 35SiMn alloy steel can be used to manufacture medium-speed and medium-load parts in the quenched and tempered state; or used as high-load and low-impact parts in the quenched and tempered state. Used for parts with larger cross-sections and surface hardening.
Name: 35SiMn alloy structural steel
Standard: GB/T 3077-1999
Application
In the general machinery industry, 35SiMn steel is used to manufacture transmission gears, main shafts, spindles, rotating shafts, connecting rods, worms, tram shafts, generator shafts, crankshafts, flywheels and large and small forgings; in steam turbine manufacturing, it is used as working temperature Below 400°C, spindles and hubs with a diameter of 250mm or less, impellers with a thickness of 170mm or less, and various important fasteners; agricultural machinery is mostly used to manufacture wear-resistant parts such as shovel handles and plow rolls. 35SiMn steel can completely replace 40Cr as quenched and tempered steel.
