ss 202 square pipe weight char

202 stainless steel is an austenitic stainless composition that offers properties comparable to Type 301. This alloy is composed of chromium, nickel, and manganese, and its creation was initially intended to reduce nickel wastage. It may become slightly magnetic when cold worked, but remains non-magnetic in its annealed form. In comparison to Type 301, this grade contains less manganese and is unable to be hardened by heat or thermal treatment; however, it can withstand high tensile strength when cold worked.

Type 202 stainless steel is counted among the many stainless steel types and is common due to its composition that bears similarities to Type 301 stainless steel. The chief difference being the marginally lower chromium and nickel content. To get a better understanding of the composition and properties of this alloy, the following sections contain more information.

Boasting many of the features found in the popular 301 stainless steel, grade 202B offers a lower concentration of chromium and nickel yet still provides a premium performance. To learn more about this alloy, please refer to our comprehensive datasheet below.

Details concerning the chemical make-up of grade 202 B stainless steel are outlined within the following table.

Prescribed amounts of Iron (Fe), Chromium (Cr), Nickel (Ni), Manganese (Mn), Silicon (Si), Carbon (C), Phosphorus (P), Sulfur (S), Molybdenum (Mo), Copper (Cu), Nitrogen (N), Selenium (Se), Titanium (Ti), Aluminum (Al), Lead (Pb), Boron (B) and Zirconium (Zr) render intricate compositions, ranging from 66.5-73% Fe, 17-19% Cr, 4-6% Ni, 7-9% Mn, 1% Si, 0.15% C, 0.060% P, 0.030% S, 2-3% Mo, 0.6% Cu, 0.1% N, 0.5% Se, 5x(C+N) Ti, 0.1% Al, 0.1 % Pb, 0.1 % B and 0. 10 % Zr in order to be crowned with the heading “Element Content (%)”.

The following outlines the physical characteristics of grade 202 B stainless steel, as indicated in the table.

Several key features characterize the properties of steel. These include a density of 8.0 g/cm (or 0.289 lb/in in imperial measurements); a melting point at 1450C (or 2640F); a yield strength of 275 MPa (or 39900 psi); a tensile strength of 515 MPa (or 74000 psi); an elongation at break of 40%; a modulus of elasticity of 193 GPa (or 28000 ksi); a bulk modulus of 140 GPa (or 20300 ksi); a shear modulus of 80.0 GPa (or 11600 ksi); a Poisson’s ratio ranging from 0.27-0.30; Reduction of area at 40%; rockwell hardness rating at 92; izod impact force unnotched at 20 J (or 14 ftlb), and notched at 16 J (or 12 ftlb). Additionally, its thermal expansion coefficient is 13.0 m/mC (or 7.2 in/inF), its thermal conductivity is 16.3 W/mK (or 113 BTU in/hr.ft.F), its specific heat capacity is 500 J/kgK (or 0.12 BTU/lb/F), and its electrical resistivity and magnetic permeability are both notable, being 0.74 cm (656 ohmcmil/ft), and 1.02 H/m)10^6, or 62.7 H/m)10^3, respectively.

Grade 202 B stainless steel boasts exceptional mechanical properties, readily accessible in the following table.
