  1. Elevated and sub-zero temperature mechanical properties of stainless steels to BS EN 10272

    BS EN 10272 is the material standard for stainless steel bars for pressure purposes. The elevated and sub-zero temperature mechanical properties shown in this article include 0.2% proof, tensile and impact (charpy) strengths. Generally, the grades included have the same chemical compositions as bar grades specified in BS EN 10088-3, which also tabulates their ambient temperature mechanical properties. The exception is grade 1.4951 which was added in the 2007 edition of the spec. Recommended annealing heat treatment temperatures for the steels covered are also tabulated.

  2. Elevated temperature mechanical properties for stainless steels specified in BS EN 10028-7

    PLEASE NOTE THAT PREVIOUS VERSIONS OF THIS ARTICLE HAD A SIGNIFICANT ERROR IN THE VALUES SHOWN FOR PROOF STRENGTHS OF DUPLEX STAINLESS STEELS. THE PRESENT ARTICLE HAS BEEN THOROUGHLY REVISED TO REFLECT THE VALUES GIVEN IN THE STANDARD. Design tensile stress values at temperatures up to 550°C are tabulated for all ferritic, martensitic and duplex types covered in the BS EN 10028-7 standard. Space limits the range of austenitic grades that can be conveniently displayed and so only a selection of some of the more 'common' the austenitic grade properties are included. Recommended annealing heat treatment temperatures for the steels covered are also tabulated.

  3. Elevated temperature physical properties of stainless steels

    Youngs 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.

  4. European EN Standard Grade Summary

    A summary of the EN standards for stainless steel products showing which grades appear in which standards.

  5. Mechanical properties for stainless steels to BS EN 10217-7

    Mechanical properties of stainless steels to BS EN 10217-7 for welded stainless steel tubes for pressure purposes.

  6. Specifying stainless steel for spring applications

    BSEN 10151 (strip) and BSEN 10272-3 (wire) for springs are outlined. The grades in each standard are tabulated and compared to the BS5770-4 and BS2056 which they replace, where grades such as 301S21 301S81 302S26 302S25 and 305S11 were specified. Grades listed include 1.4016 1.4021 1.4028 1.4031 1.4568 (17/7 PH type) 1.4310 1.4301 1.4401 1.4369 1.4372 and 1.4568 Mechanical properties in the cold worked (temper rolled for strip, drawn for wire) conditions are shown. Heat treated properties for precipitation hardening grade 1.4568 wire are also shown.

    A summary of datasheets for tubular products

  8. Stainless steel fasteners

    Stainless steel bolts, screws, studs and nuts are specified to BS EN ISO 3506. The chemical composition and mechanical properties of austenitic, martensitic and ferritic grades are covered

  10. Tolerances to BS EN 10297-2 for seamless stainless steel tubes

    In addition to chemical composition and mechanical properties, BS EN 10297-2 also gives tolerances for straightness, outside diameter, wall thickness and length
