  1. A fabrication and erection specification for stainless steel – DD ENV 1090 Part 6

    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.

  2. BS EN 10204 test certificates for stainless steel products

    Test certificate types 2.1, 2.2, 2.3, 3.1, 3.1B, 3.1A, 3.1C and 3.2 to the 1991 and 2004 editions of BSEN 10204 are described. The 2004 edition has simplified the range of certificate types to only include types 2.1, 2.2, 3.1 and 3.2. Type 3.1 replaces 3.1B and type 3.2 replaces 3.1A, 3.1C and 3.2 of the previous 1991 edition. The 1991 version of EN 10204 was based on the original German DIN 50049.

  3. Calculating the deflections of stainless steel beams

    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)

  4. Comparison of 304 or 316 and 304L or 316L type compositions and effect on corrosion resistance

    The carbon ranges of ‘normal’ and ‘low’ carbon 304, (304L) and 316, (316L) types are compared. The effect of carbon on intercrystalline corrosion resistance and welding is also covered and why steel is often offered as a dual certified product. European grades 1.4301 1.4306 1.4307 1.4401 and 1.4404 are included in the comparisons.

  5. Comparison of structural design in stainless steel and carbon steel

    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)

  6. Dual (multiple) certification of stainless steel products

    Dual certification involving either multiple standards, (EN or ASTM), or standard, e.g. 1.4301 and low carbon, e.g. 1.4307, grades for the same batch of steel is outlined. Full compliance of all product attributes certified on multiple standard certificates is unlikely. The concept of a primary certified standard is outlined.

  7. EN 1090 – A Guide for Stainless Steel

    A guide to EN 1090 for stainless steel related issues

  8. Stainless steel sections for structural applications

    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.
