Heat Treatment of C45 Plate

C45 plate belongs to high quality carbon structure steel. Do you know the heat treatment of C45 plates, the hardening, quenching and tempering? For heat treat of C45 plates, please check it below.
Heat treatment of C45 plates:
1. Prior to the C45 plate hardening without tempering, hardness of HRC55 (up to a maximum of HRC62) is qualified. Practical application of the maximum hardness of HRC55 (high-frequency quenching HRC58).
2. C45 plate instead of carburizing and quenching heat treatment process. After quenching and tempering component with good mechanical properties, is widely used in a variety of important structural parts, especially those working in alternating load connecting rods, bolts, gears and shafts, etc. But the lower surface hardness, not abrasion resistant. Surface hardening improves the surface hardness of quenched and tempered + available.
Carburizing treatment of C45 plate:
1. Carburizing treatment commonly used overloaded parts of the core-surface wear resistance, impact resistance, high wear resistance than surface hardening with tempering +. Carbon content in the surface 0.8--1.2%, General 0.1--0.25% core (special cases using 0.35%). After heat treatment, surface can get very high hardness (HRC58--62), the core of low hardness, impact resistance.
2. If C45 plate carburizing, quenching core of hard and brittle Martensitic appears, lost advantages of carburizing treatment. Material of carburizing process now, carbon is not high, and 0.3% core strength can reach very high, applications are rare.
C45 plate has high hardness cutting processing, and can be used in mould used in templates, tips, guide post, subject to heat treatment.
