S45C / SAE1045 Medium Carbon Tool Steel Used In Machinery Manufacturing
S45C carbon tool steel
C45 steel is called GB, also known as "oil steel." Most of the spot market is hot-rolled; cold-rolled specifications 1.0 ~ 4.0mm (mm) between.
The steel cold plastic general, annealing, normalizing slightly better than the quenched and tempered, with high strength and better machinability.

Feature
Common carbon quenched structural steel.
The steel cold plastic general, annealing, normalizing slightly better than when quenched and tempered, with high strength and better machinability, after appropriate heat treatment can obtain a certain degree of toughness, ductility and wear resistance, the source of the material Convenience.
Suitable for hydrogen welding and argon arc welding, not suitable for gas welding. Preheat before welding, after welding should be stress relief annealing.
Normalizing can improve the hardness of less than 160HBS rough cutting performance. The quenched and tempered steel, the comprehensive mechanical properties to be optimized in other carbon structural steel, but the hardenability of the steel is low, the critical water quenching diameter of 12 ~ 17mm, water cracking tendency.
When the diameter is greater than 80mm, after quenching or normalizing, the mechanical properties are similar, medium and small mold parts after quenching and tempering to obtain higher strength and toughness, and large parts, then normalized to appropriate , So this steel is usually used in the quenched or normalized state.
Heat treatment
Recommended heat treatment temperature: normalizing 850, quenching 840, tempering 600.
1. 45 steel quenching after no tempering, hardness greater than HRC55 (up to HRC62) is qualified.
Practical application of the highest hardness of HRC55 (high-frequency quenching HRC58).
2.45 steel do not use carburizing quenching heat treatment process.
Supply status hardness 137 ~ 170HBS, 167 ~ 229HBS, 201 ~ 269HBS
Delivery Time
Stock items 15-20 days; customized items 30-50 days.
Packing: Standard export packing; customers' special requests are accepted
More about S45C carbon tool steel
S45C steel as high-quality carbon structural steel, hardness is not easy to cut, the mold is often used to make templates, pins, guide columns, etc., but to be heat treatment.
1. After quenching steel without tempering, hardness greater than HRC55 (up to HRC62) is qualified.
Practical application of the highest hardness of HRC55 (high-frequency quenching HRC58).
2. Steel do not use carburizing and quenching heat treatment process.
Quenched and tempered parts have good overall mechanical properties and are used in a wide range of important structural components, especially those that work under alternating loads such as connecting rods, bolts, gears and shafts. But the surface hardness is low, not wear-resistant. Available quenching + surface hardening parts surface hardness.
