C45 steel is an unalloyed channel carbon engineering metal containing 0. 42%-0. five per cent And also carbon. It offers modest tensile benefits, wear weight and fine machinability. this kind of material is capable involving through hardening by quenching and tempering on constrained sections, and also could be fire or inauguration ? introduction hardened for you to surface firmness Min 55HRC. C45 is usually generally supplied in the unattended or normalised issue using a typical tensile durability range 570 - 600 Mpa and Brinell solidity range 170 - 210.
1. Supply Form as well as Size & Tolerance
Sizzling rolled bar: Φ6-Φ130mm, Span: 3000-10000mm
Hot Forged spherical bar: Φ130-Φ1000mm, Length: 3000-10000mm
Flat bar/Blcoks: Thickness: 120-800mm xWidth: 120-1500mm, Length: 2000-6000mm
5. Forging
C45 iron forging temperature: 900 rapid 1100°C, cooling as slowly and gradually as possible in nonetheless air flow or in mud soon after forged.
6. High temperature Cure
