  1. Chemical compositions of stainless steels to BS 6323-8

    BS 6323 was the material standard for steel seamless and welded tubes for automobile, mechanical and general engineering purposes. Part 8 covered the requirements for longitudinally welded stainless steel tubes. This standard has been withdrawn and replaced by BSEN 10296-2 in December 2005. The chemical composition of stainless steel grades that were covered in BS 6323-8 included LW12 LW19 LW20 LW21 LW22 LW23 and LW24. These designations are related to the obsolete BS 1449-2 sheet grades 409S19 304S11 304S15 316S13 316S33 and 321S31 from which the welded tubes would have been made.

  2. Chemical compositions of stainless steels to BS EN 10217-7

    BS EN 10217-7 2014 is the European standard: Welded stainless steel tubes for pressure purposes- Technical delivery conditions. It contains austenitic and duplex stainless steels. There are no ferritic, martensitic or heat resisting steels.

  3. Chemical compositions of stainless steels to BS EN 10253-3 and 10253-4

    BS EN 10296-3 and 10253-4 are the material standards for austenitic and duplex stainless steels for butt-welding fittings without and with specific inspection requirements. They were published in December 2008.

  4. Chemical compositions of stainless steels to BS EN 10269

    BS EN 10269 is the material standard for stainless and heat-resisting steels, a selection of low alloy steels and some nickel alloys for fasteners. The chemical composition of stainless steel grades covered in the this standard include 1.4307 1.4301 1.4303 1.4404 1.4401 1.4429 1.4567 1.4923 1.4938 1.4913 1.4982 1.4910 1.4919 1.4941 1.4980 and 1.4986

  5. Chemical compositions of stainless steels to BS EN 10296-2

    BS EN 10296-2 is the material standard for stainless and heat-resisting steels for circular welded tubes for mechanical and general engineering (ie not pressure) purposes. It replaced BS6323-8 on its publication in December 2005. The chemical compositions of steel grades covered in the this standard include are tabulated in this article and include: 1.4003 1.4512 1.4016 1.4510 1.4521 1.4526 1.4509 1.4318 1.4307 1.4306 1.4311 1.4301 1.4541 1.4550 1.4404 1.4401 1.4571 1.4432 1.4429 1.4436 1.4435 1.4439 1.4539 1.4547 1.4362 1.4462 1.4410 1.4828 1.4835 1.4833 1.4845 1.4818 and 1.4854

  6. Chemical compositions of stainless steels to BS EN 10297-2

    BS EN 10297-2 is the material standard for stainless and heat-resisting steels for seamless tubes for mechanical and general engineering (ie not pressure) purposes. It was published in December 2005 but does not replace any previous British Standard, unlike BS EN 10296-2 which replaced BS6323-8. The chemical compositions of steel grades covered in the this standard include are tabulated in this article and include: 1.4512 1.4002 1.4016 1.4510 1.4006 1.4307 1.4306 1.4311 1.4301 1.4305 1.4541 1.4550 1.4335 1.4404 1.4401 1.4466 1.4571 1.4580 1.4429 1.4436 1.4435 1.4439 1.4563 1.4539 1.4547 1.4529 1.4558 1.4362 1.4460 1.4477 1.4462 1.4507 1.4410 1.4501 1.4424 1.4749 1.4878 1.4835 1.4833 1.4845 1.4876 and 1.4854

  7. Chemical compositions of stainless steels to EN 10216-5

    BS EN 10216-5 2004 is the European standard: Seamless stainless steel tubes for pressure purposes- Technical delivery conditions. It contains austenitic, duplex, creep resisting stainless steels. There are no ferritic, martensitic or heat resisting steels.

  8. Comparison of 316 BS and EN Grades

    The former BS1449 and BS970 316 type grades 316S12 316S16 316S11 316S13 316S31 and 316S33 are compared and matched to the current EN steel number grades. Composition ranges for the ?BS? grades are given. For atmospheric exposure service conditions, except in extreme marine environments, the substitution of either: -316S11 (1.4404) for 316S12 or316S31 (1.4401) for 316S16 should give satisfactory corrosion resistance, depending on design and finishing techniques.

  9. Comparison of composition ranges of 316 type stainless steels

    This article compares the chemical composition of a number of 316 type grades as covered by the now superseded BS1449 and BS970 and their replacement, BS EN 10088 Parts 2 and 3. Grades covered include 316S11 316S12 316S13 316S16 316S31 316S33 and European steel numbers 1.4401 1.4404 1.4432 and 1.4436

  10. Elevated and sub-zero temperature mechanical properties of stainless steels to BS EN 10269

    BS EN 10269 is the material standard for stainless and heat-resisting steels, a selection of low alloy steels and some nickel alloys for fasteners. The elevated and sub-zero temperature mechanical properties shown in this article include 0.2% proof, tensile and impact (charpy) strengths.
