Carbon Steels S45C

Identification type 1. Often by grinding with a grinding wheel, see the sparks, white is high carbon steel, such as 45 steel, red is A3 steel. 2. The material of 45 steel and Q235 is ground on the stone, and Q235 is easily ground off. 3. With a hammer, the mark of 45 steel is much shallower than the mark of Q235(A3), because Q235 is much softer than 45 steel.

Product Introduction

Carbon steels are a category of steel that contains carbon as the primary alloying element. S45C is a specific type of carbon steel that contains approximately 0.45% carbon content. It is known for its excellent machinability, high strength, and good toughness. S45C carbon steel is commonly used in manufacturing applications, such as gears, shafts, and axles, due to its excellent mechanical properties. It can also be heat treated to improve its properties further. Carbon steels like S45C are widely used in various industries, including automotive, machinery, and construction.

Below are some of the product specifications for S45C carbon steels:

1. Chemical Composition: S45C carbon steels are classified as medium carbon steel, with a composition of 0.42-0.48% carbon, 0.6-0.9% manganese, and 0.15-0.35% silicon.

2. Mechanical Properties: S45C carbon steels possess excellent strength and toughness, making them suitable for applications that require high durability and reliability. Their typical tensile strength ranges from 570-700 MPa, while their yield strength is approximately 300-490 MPa.

3. Hardness: S45C carbon steels have a hardness range of 170-210 HB, which makes them suitable for applications that require good wear resistance.

4. Machinability: S45C carbon steels have good machinability, ensuring that they can be easily shaped, cut, and drilled for use in various manufacturing processes.

5. Weldability: S45C carbon steels are highly weldable, making them ideal for applications that require welding.

S45C Chemical composition standards and properties

AISI 1045 Steel Round Bar Sheet Plate

S45C Heat Treatment

Annealing : Heat to 800 ^oC – 850 ^oC hold until temperature is uniform throughout the section, and cool in furnace.

Flame or Induction Hardening

Heat as quickly as possible to the austenitic temperature range (820 ^oC – 860 ^oC) and required case depth followed by an immediate water or oil quench, depending upon hardness required, workpiece size/shape and quenching arrangements.

Following quenching to hand warm, most components should be tempered at 150 ^oC – 200 ^oC to remove quenching stresses in the case. This will have little effect on case hardness.

C45 steel Hardening

Heat to 820 ^oC – 850 ^oC hold until temperature is uniform throughout the section, soak for 10 – 15 minutes per 25mm of section, and quench in water or brine.
or:Heat to 830 ^oC – 860 ^oC soak as above and quench in oil.Temper immediately while still hand warm.

45C steel Normalizing

Heat to 870 ^oC – 920 ^oC hold until temperature is uniform throughout the section, soak for 10 – 15 minutes.

Cool in still air.

Stress Relieving

Heat to 550 ^oC – 660 ^oC hold until temperature is uniform throughout the section, soak for 1 hour per 25mm of section, and cool in still air.

S45C steel Tempering

Re heat to 400 ^oC – 650 ^oC as required, hold until temperature is uniform throughout the section, soak for 1 hour per 25mm of section, and cool in still air.
