Description
EN32B – Bright Bar Grade Introduction:
EN32B is a carbon case hardening steel known for its strength and wear resistance when carburized. This steel grade is commonly used in general engineering applications where components require a hard-wearing surface and a tensile strength in the range of 430-490 N/mm². EN32B is readily machinable and weldable in its supply condition, making it suitable for lightly stressed components.
EN32B – Bright Bar Application:
EN32B bright bars are used in a variety of engineering applications, including:
- General engineering components
- Lightly stressed parts
- Carburized components for enhanced surface hardness
