Grade 420:
420 grade stainless steel has a composition of 12 to 14 percent
chromium, 0.15 percent carbon, 1 percent manganese, 1 percent
silicon, and tiny amounts of phosphorus and sulfur. 440 grade
stainless steel has higher amounts of chromium -- 16 to 18 percent
-- and carbon at 0.6 to 0.75 percent.
