Structural Steel 101: Shapes, Properties, and Applications- free cutting steel properties table ,Medium- and high-carbon structural steel requires from 0.31 to 1.50% carbon by weight, making this steel suitable for mechanical engineering applications. Structural steel can also contain levels of manganese, phosphorus, sulfur, and silicone, among other materials. While manufacturers can add additional metals such as chromium, titanium, and ... 11SMn30 ( 1.0715 ) - Steel Number9. Brinell hardness (HBW): (+SH) 107 - 169. Properties of steel 11SMn30 (1.0715) Weldability: Due to the high sulphur and phophorus content free-cutting steels not destined to heat treatment are not generally recommended for welding. Machinability: This steel grade is marked by a good machinability on machine tools and by an easy fragmentation ...
With a higher carbon content these free-cutting steels can be quenched and tempered, but still maintain a good machinability even with lower sulfur percentages. The bars can be supplied in heat treated condition, in order to avoid heat-treating the pieces after machining. When quenched and tempered, these steels have elevated mechanical
The Chop saw is a great way to cut steel with straight / square cuts (and most angles). The circular saw is more maneuverable, cheaper and smaller than a Chop saw. Circular saws are also great for cutting sheets of metal and bigger stuff that you can’t put into a chop saw.

Tables of properties of stainless steels Sheet metal in detail . Those who bend stainless steel knows we are dealing with an extremely diversified and complex class of materials. Stainless steel pressbrake bending, as well as cutting, welding, treatments and machining must be adapted according to the alloy and its final usage.
Free cutting steel, also refers as the free-machining steel, is the alloy steel by the addition of one or more free cutting elements such as sulfur, phosphorus, lead, calcium, selenium and tellurium to improve its cutting property. Free cutting steel is characterized by its excellent cutting performance.
“capped,” or “rimmed.” The degree of deoxidation affects some of the properties of the steel. In addition to oxygen, liquid steel contains measurable amounts of dissolved hydrogen and nitrogen. For some critical steel applications, special deoxidation practices as well as vacuum treatments may be used to reduce and control dissolved gases.

It’s actually used to measure the amount of energy the material can absorb at the limited state. 6) Shear strength: the maximum shear load a material can withstand before failing divided by its cross-sectional area. Generally, Steel, Titanium, Tungsten and Inconel are considered the strongest four metals.
The Chop saw is a great way to cut steel with straight / square cuts (and most angles). The circular saw is more maneuverable, cheaper and smaller than a Chop saw. Circular saws are also great for cutting sheets of metal and bigger stuff that you can’t put into a chop saw.
Free-Cutting ( Free-Machining [6]) Steel is a nickname for carbon steel with an increased amount of alloying elements for the sole purpose of improving their machinability. 11xx series: the amount of Sulfur (S) is increased from 0.05% in plain carbon steels to 0.1%. It adds about 20% to the machinability when compared with the equivalent ...

Free cutting steels with lead also allow for higher machining rates. As a thumb rule, free cutting steel normally costs 15 % to 20 % more than the standard steel. However this is made up by increased machining speeds, larger cuts, and longer tool life. The cutting (machining) operation is shown in Fig 1. Fig 1 Cutting operation
Free Cutting Steel Grade Equivalent Table - Songshun Steel Free cutting steel which is the alloy steel be added certain amount of sulfur, phosphorus, lead, calcium, selenium, tellurium and other elements to improve the machinability. As the development of machining technology, the requirements for machinability of steel is more and more important.

Multiply by number of petals = permiter. Once you have the perimeter the punching force PF becomes: PF = Perimeter x Thickness x Shear Strength. Steel cans vary from .14″ to about .11″. So the perimeter times about .13″ gives the cross sectional area being sheared. And low carbon steel is about 40,000 lbs/square inch.
