High Carbon Plates

Hard, high-strength plate with 0.40%+ carbon for tools and wear parts.

Overview

Material overview

Increasing carbon as the main alloy is the economical approach to steel hardness and high strength; the fine pearlite structure makes the steel harder, though more brittle and less ductile than mild steel.

Elevated carbon levels also reduce weldability, impact toughness and ductility — grade selection should match the fabrication route.
