In 2009, Crucible Steel introduced an update to CPM-S30V to meet the needs of renowned knife maker Chris Reeve that they called CPM-S35VN. The addition of 0.5% Niobium, and reductions in both Carbon (from 1.45% to 1.40%) and Vanadium (from 4% to 3%) produced an alloy with 25% increase in measured Charpy V-notch toughness over S30V (Crucible claims 15-20% improvement).
This leads to the possibility of smelters taking coins and melting them down for the scrap value of the metal. Pre-1992 British pennies were made of 97% copper; but as of 2008, based on the price of copper, the value of a penny from this period is 1.5 new-pence. Modern British pennies are now made of copper-plated steel.
Stainless steel, also known as inox, corrosion-resistant steel (CRES), and rustless steel, is an alloy of iron that is resistant to rusting and corrosion. It contains iron with chromium and other elements such as molybdenum , carbon , nickel and nitrogen depending on its specific use and cost.
SAE Type 630 stainless steel (more commonly known as 17-4 PH, or simply 17-4; also known as UNS S17400) is a grade of martensitic precipitation hardened stainless steel. It contains approximately 15–17.5% chromium and 3–5% nickel, as well as 3–5% copper. [1] The name comes from the chemical makeup which is approximately 17% chromium and 4 ...

SAE 316L grade stainless steel, sometimes referred to as A4 stainless steel or marine grade stainless steel, is the second most common austenitic stainless steel after 304/A2 stainless steel. Its primary alloying constituents after iron , are chromium (between 16–18%), nickel (10–12%) and molybdenum (2–3%), up to 2% manganese , [ 1 ] with ...
