Mechanical & Physical Properties

  1. Ambient temperature physical properties of stainless steels to BS EN 10088-1

    Ambient temperature physical properties, including density, modulus of elasticity, (Young’s modulus), coefficient of thermal expansion, thermal conductivity, specific heat, (heat content or heat capacity), and electrical resistivity for a range of ferritic, martensitic, austenitic and duplex stainless steel types are tabulated. Some explanation of the units used for these properties is given.

  2. Elevated temperature physical properties of stainless steels

    Young’s modulus and thermal expansion data is tabulated for a range of commonly used grades shown in BS EN 10088-1. More detailed ‘typical’ data follows for austenitic steel types only from the INCO publication ‘Austenitic chromium-nickel stainless steels-engineering properties at elevated temperatures’, including tensile and shear modulus data, Poisson’s ratio, density, thermal expansion, conductivity, specific heat and electrical resistivity.

  3. On-site methods for stainless steel grade product sorting

    Guidance on methods for sorting stainless steels from low alloy and carbon steels is shown. These include physical, (colour, density, magnetic), and mechanical, (hardness), properties and chemical tests, (copper sulphate, copper chloride, nitric acid and sulphur tests). A suggested approach to a step-by-step procedure for differentiating stainless steels from carbon steels is tabulated. These methods have not been verified by the BSSA, who take no responsibility for their accuracy of the conclusions reached on steel types.

  4. Structural design of stainless steel

    Basic design data for the grades of stainless steel typically used in structural applications are presented. This includes design strength, (py), expressed as the specified proof strength, Young’s modulus, (modulus of elasticity), Poisson’s ratio, shear modulus, density, thermal expansion coefficient, thermal conductivity and heat capacity. Brief guidance on designing structural stainless steel is also given, where the differences between carbon steel and stainless steel’s buckling resistance and member deflections are explained. Grades listed include type 304, 304L, 316, 316L and 2205, European steel grades 1.4301, 1.4307, 1.4401, 1.4404, 1.4462, duplex (141)
