The manganese steel plates were replaced with much lighter 25 mm (1.0 in) molybdenum steel plates allowing for higher speed, greater maneuverability, and better protection. [20] The Germans also used molybdenum-doped steel for heavy artillery, like in the super-heavy howitzer Big Bertha , [ 49 ] because traditional steel melts at the ...
Type 316—the second most common grade (after 304); for food and surgical stainless steel uses; alloy addition of molybdenum prevents specific forms of corrosion. It is also known as marine grade stainless steel due to its increased resistance to chloride corrosion compared to type 304. 316 is often used for building nuclear reprocessing plants.

41xx steel is a family of SAE steel grades, as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum, and as a result these materials are often informally referred to as chromoly steel (common variant stylings include chrome-moly, cro-moly, CrMo, CRMO, CR-MOLY, and similar).
Carbon steel is a popular choice for rough-use knives and cheaper options. Carbon steel used to be much tougher, much more durable, and easier to sharpen than stainless steel. This is no longer the case since the coming of super-advanced alloy metallurgy such as VG-10 and SG-2 powder steel for example.
SAE 316 stainless steel is a molybdenum-alloyed steel and the second most common austenitic stainless steel (after grade 304). It is the preferred steel for use in marine environments because of its greater resistance to pitting corrosion than most other grades of steel without molybdenum. [1]
Molybdenum: 0.2–5 Stable carbides; inhibits grain growth. Increases the toughness of steel, thus making molybdenum a very valuable alloy metal for making the cutting parts of machine tools and also the turbine blades of turbojet engines. Also used in rocket motors. Nickel: 2–5 Toughener 12–20 Increases corrosion resistance Niobium —
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 ...
