5160, a spring steel. Popular steel for forging swords and large knives, with high toughness and good wear resistance. [citation needed] Popular sword manufacturers that use 5160 spring steel include Hanwei and Generation 2. [citation needed] 5160 spring steel is mainly used on Medieval type swords. [citation needed] 4140 [definition needed]
Spring steel is a name given to a wide range of steels [1] used in the manufacture of different products, including swords, saw blades, springs and many more. These steels are generally low-alloy manganese , medium-carbon steel or high-carbon steel with a very high yield strength .
Tool steel is any of various carbon steels and alloy steels that are particularly well-suited to be made into tools and tooling, including cutting tools, dies, hand tools, knives, and others. Their suitability comes from their distinctive hardness , resistance to abrasion and deformation, and their ability to hold a cutting edge at elevated ...
Very hard steel (e.g. chisels, quality knife blades): HRC 55–66 (Hardened High Speed Carbon and Tool Steels such as M2, W2, O1, CPM-M4, and D2, as well as many of the newer powder metallurgy Stainless Steels such as CPM-S30V, CPM-154, ZDP-189. There are alloys that hold a HRC upwards 68-70, such as the Hitachi developed HAP72.

Tool steels, for example, may have elements like chromium or vanadium added to increase both toughness and strength, which is necessary for things like wrenches and screwdrivers. On the other hand, drill bits and rotary files need to retain their hardness at high temperatures.
Vanadis 4 Extra is a chromium-molybdenum-vanadium alloyed tool steel produced by Uddeholms AB. It is intended for powder metallurgy cold forming operations on materials such as annealed austenitic stainless steel , mild carbon steel , copper and aluminium .
A36 steel has a Poisson's ratio of 0.26 and a shear modulus of 11,500 ksi (79.3 GPa). [ 7 ] A36 steel in plates, bars, and shapes with a thickness of less than 8 inches (203 millimeters) has a minimum yield strength of 36 ksi (250 MPa ) and ultimate tensile strength of 58–80 ksi (400–550 MPa).
