What is ISO 6306 about?
ISO 6306 is a safety standard on the chemical analysis of steel.
ISO 6306 specifies an order for listing elements within the chemical composition of steels and most other iron-based alloys, excluding foundry irons.
The elements are divided into three groups. These groups have no technical significance, but they are considered to provide the easiest means of readily remembering.
NOTE: ISO 6306 has been developed and is used by ISO/TC 17/SC 4 but can also be used by other ISO/TC 17 subcommittees.
Who is ISO 6306 for?
ISO 6306 on the order of listing elements in steel standards is relevant to:
- Producers, specifiers, and fabricators of steel mill products
- Manufacturers of alloy steels, stain steels, tool steels, and carbon steels
- Chemical engineers
- Mechanical engineers
- Metallurgical engineers
Why should you use ISO 6306?
The modern tendency towards international standardization and the use of computers for storing, processing, and retrieving information has increased the case for standardizing the order of listing elements. This is particularly so when data from several sources are processed by a single computer. Consequently, there is a growing awareness of the long-term advantages of national and international standardization.
ISO 6306 is especially important for ISO/TC 17/SC 4 as it is concerned with a series on numerous heat treatable and stainless-steel grades. A certain level of international agreement has already been achieved in steel specifications developed by ISO/TC 17/SC 4 for the elements of the first group and this has been incorporated into the recommendations given in ISO 6306. ISO 6306 is based on the withdrawn technical report, ISO/TR 6306:1989.
Overall, ISO 6306 is useful as it assists the user with the order of listing elements in steel standards, which can be of good help in your business.
What’s changed since the last update?
BS ISO 6306:2020 supersedes BS ISO 6306:2019, which is withdrawn.
BS ISO 6306:2020 replaces the first edition (ISO 6306:2019), which has been technically revised. The main changes compared to the previous edition are as follows:
- Recommended order of the first group of listing elements in steel standards was changed
