Low-carbon steel contains approximately 0.050.25% carbon making it malleable and ductile. Hardness is important from an engineering standpoint because resistance to wear by either friction or erosion by steam, oil, and water generally increases with hardness. >> PH stainless steels (precipitation-hardening) contain around 17% chromium and 4% nickel. << Hardnessis probably the most poorly defined material property because it may indicate resistance to scratching, resistance to abrasion, resistance to indentation or even resistance to shaping or localized plastic deformation.
