Carbon & Alloy Sheets & Plates

Carbon steel plate fall into three typical categories:
low carbon = .06% to .25% carbon content (mild steel)
medium carbon = .25% to .55% carbon content (medium steel)
high carbon = >.55% to 1.00% carbon content (hard steel)

Alloy steel plate fall into two typical categories:
low alloy = 1% up to 5% alloying agents added
high alloy = from 5% - 50% alloying agents added
 

Alloying agents include:

• Manganese (common)
• Nickel (common)
• Chromium (common)
• Molybdenum (common)
• Vanadium (common)
• Silicon (common)
• Boron (common)
• Aluminum, cobalt, copper, cerium, niobium, titanium, tungsten, tin, zinc, lead, zirconium (less common)
