Design & Design Strengths

The stiffness of a stainless steel component varies with the stress level, the stiffness decreasing as the stress level increases. Consequently deflections are greater in stainless steel beams than in carbon steel beams. This article explains how to calculate the deflection in a stainless steel beam. (206)
-
This article highlights the differences between designing structural components in carbon steel to those in stainless steel. The stress-strain behaviour and mechanical properties are compared and the implications on structural behaviour described. (205)
-
Issues relating to the design of stainless steel handrails and balustrades are discussed. Section availability and grade selection are also covered.

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)

Structural stainless steel sections are being used increasingly as the particular characteristics of stainless steel are more widely understood. This article provides a link to the Stainless Steel Sections Directory which shows data on the sections available and the potential suppliers of such sections
