Total hardness Vickers ranges apply to ferritic and austenitic types only. Precipitation hardening grade 1.4568 should also be available in the solution annealed condition. Martensitic grades 1.4021, 1.4028 and 1.4031 should also be available in the annealed condition. Values are maxima, unless there is a range stated.Īvailable tensile strength levels in MPa (N/mm 2) are:. The compositions of all the grades are shown below. (TR230, TR280, TR330, TR380 etc depending on grade) BS EN 10151 grades and delivery conditions BS EN 10151 uses tensile strength ranges, rather than the Vickers hardness ‘conditions’ of BS5770:4. The other main difference between the standards is the way in which the ‘spring temper’ is specified. The BS EN 10151 has a more comprehensive scope than BS5770:4.īS EN 10151 grade 1.4310 is the alternative to BS5770 grade 301S21, 1.4301, the alternative to 302S25 and 1.4401 the alternative to 316S16 in the austenitic types. The composition of grade 1.4369 has been designed to keep the steel non-magnetic in all conditions. With the exception of austenitic grade 1.4369, (X11CrNiMnN19-8-6), the grade compositions are covered by BS EN 10088-2.
It contains 10 grades, one ferritic, three martensitics, one precipitation hardening and five austenitic. Both standards use the European steel grade number system, most of which are also shown in BS EN 10088-1 BSEN 10151 stainless steel strip for springsīS EN 10151 was published in 2002 and replaced BS5770 part 4, (1981), which is now withdrawn.

BS EN ISO 6931-1:2020 applies to wire and replaces BS EN 10270-3:2001 which had previously replaced BS2056:1991, full details of the historical evolution of the standards can be found at the BSI website. BS EN 10151:2002 applies to strip and replaces BS5770 part 4:1981, which is now withdrawn. Specifying stainless steel for spring applications IntroductionĮuropean standards now cover both strip and wire products for springs.
