1045/S45C/CK45 Carbon Solid Round bar for Shaft

Round solid long steel
1045/S45C/CK45 round steel refers to solid long steel strips with a circular cross section. Small round steel is often used as steel bars, bolts and various mechanical parts, while large round steel is used to manufacture mechanical parts or as seamless steel pipe blanks.

45#/1045/S45C round steel refers to solid long steel strips with a circular cross section. Its specifications are expressed in millimeters of diameter, such as “50” means round steel with a diameter of 50 mm. 1045/S45C/CK45 round steel is divided into three types: hot-rolled, forged and cold-drawn. The specifications of hot-rolled round steel are 5.5-250 mm. Among them: 5.5-25 mm small round steel is mostly supplied in bundles of straight bars, and is often used as steel bars, bolts and various mechanical parts; round steel larger than 25 mm is mainly used to manufacture mechanical parts or as seamless steel pipe blanks.

Good quality Motorcycle crankshafts from a Chinese manufacturer

Motorcycle crankshaft：

The working principle of the motorcycle crankshaft

The crankshaft of a motorcycle is a component that ignites the gasoline in the engine. The gasoline combustion work drives the live race down, and then drives the crankshaft to rotate. It also depends on the inertia of the crankshaft to maintain operation when it is not ignited. As long as the engine is started, the crankshaft will continue to rotate, and drive the magneto to generate electricity, charge the battery and use it for power devices in the car. If the gear does not go, it means pinch-clutch (hand-clutched models) or idling (auto-clutch models such as pedals or curved beams). At this time, the crankshaft is still rotating. Bending beam or pedal) the car will not go, the resistance of the engine is slightly increased, but the effect is very small, and the engine speed in neutral is the same.

The motorcycle crankshaft is one of the most important parts in the internal combustion engine. It connects the piston, connecting rod and camshaft. Its main function is to convert the reciprocating motion of the piston into the rotational motion of the output shaft, thereby driving the operation of the motorcycle.

The crankshaft consists of multiple cranks, each of which is connected to a piston and a connecting rod. When the piston moves up and down in the cylinder, the connecting rod drives the crank to rotate, and finally converts the reciprocating motion of the piston into the rotational motion of the output shaft. This motion conversion method allows the motorcycle to run smoothly and provides enough power to drive the vehicle.

The design and manufacture of the crankshaft need to take into account many factors, such as strength, weight, thermal expansion coefficient, noise and fuel consumption. Modern motorcycle manufacturers usually use high-performance alloy materials to manufacture crankshafts to improve their performance and durability.

Heat Treatment:
Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each EN30B steel component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of this 4.25% nickel alloy steel.

ForgingHeat the steel carefully to the forging temperature of 1000-1100°C, soak well. After forging, cool slowly in a furnace to 100°C maximum and anneal immediately.
AnnealingTo obtain the softest condition heat carefully to 630-650°C. Soak for a minimum of 2 hours, then cool in the furnace or in air. It is advisable to repeat this treatment to obtain the best machining characteristics.
Stress RelievingWhere the machining operations have been severe, we recommend stress relieving EN30B alloy steel before finish machining and hardening. Heat carefully to 630-650°C then cool in the furnace or in still air.
HardeningHeat uniformly to 810-830°C and when thoroughly soaked at this temperature cool in air or quench in oil according to mass. Hardening from neutral salt baths will help to prevent scaling or decarburisation and is strongly recommended. Pre heat at 300-400°C, raise to the hardening temperature of 810-830°C, quench into salt standing at 300-320°C.  Withdraw and cool in air. Alternatively, tools may be vacuum hardened. If desired, hardened and tempered tools can be cyanide hardened to give a shallow carburised case to die surfaces with increased hardness values up to Rockwell C56-60. Temper as soon as tools are hand-warm.
TemperingRe heat to the relevant tempering temperature. Soak for at least 2 hours per 25mm of ruling section. Withdraw from the furnace and cool in still air. Tempering between 275-450°C is not advised as tempering within this range will reduce the impact value.
