DD ENV 1090 Part 6 is the new fabrication and erection specification for stainless steel. It covers austenitic and duplex stainless steels used in buildings and other similar steel structures.

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.

This article describes the contents of the Architects’ Guide to Stainless Steel, an online resource containing an extensive amount of architectural information concerning stainless steel. The topics covered include grade selection, product forms, durability, economics, production and fabrication, surface finish, joining, maintenance and cleaning. The computer aided learning package Stainless SteelCAL is also described.

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)

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.

Paper originally delivered at the BSSA Conference ‘Stainless Solutions for a Sustainable Future’ held in Rotherham on 3rd April 2003. This paper describes a study where 2 high strength austenitic stainless steels and 3 carbon steels used at Volvo Cars Body Components, were compared. The differences in formability and crash absorbing capability of specific components made from these steels, during plastic deformation, are shown. Tensile, (stress-strain curves), and forming limit curves are compared. Forming limit dome tests are better for assessing steels subject to microstructural changes during deformation. Component stamping trials are described and analysed.

This article describes what types of structural stainless steel sections are available and how they can be procured. It outlines what sections are available ex-stock and which may need to be made-to-order. Ranges of dimensions for hollow and bar sections are given.
