Comparison of composition ranges of 316 type stainless steels

The specification of bar (to BS970) and coil / plate (to BS1449) before 1983 covered two type 316 grades: a 'low' carbon with 0.03% max (316S12) and a 'standard' carbon with 0.07% max 316S16. Both had a molybdenum content in the range of 2.25-3.0 %.

Stainless Steel Fastener Grades to BS EN ISO 3506

BSENISO 3506 replaces BS6105. Part 1 covers bolts, screw and studs, part 2 nuts and part 4 tapping screws. Grades A1 to A5 are described and fastener grade selection is covered in annexes to the standards. The standards lists grades 1.4439 1.4539 (904L) 1.4529 (6% molybdenum austenitic) and 1.4462 (2205) as suitable for reducing the risk of chloride induced stress corrosion cracking failures in applications such as indoor swimming pools.

European Standardisation

The background to the publication of EN10088 parts 1, 2 and 3 and EN10095 is described. Part 1 covers chemical compositions and some physical properties of the European stainless steel grades. Part 2 covers flat products ie sheets and plates, with their mechanical properties and replaces BS1449 part 2 1983. Part 3 covers long products ie bars and sections and replaces BS970 part 1. EN10095 covers Heat Resisting Steels and Nickel Alloys in all product forms. These only cover general engineering purposes. Pressure purposes are covered by EN10028 part 7 (flat products) and EN 10272 (long products). A summary table of standards is shown, which includes the separate dimensional tolerance standards.

The Stainless Steel Family

What is stainless steel ?

Stainless steel is the generic name for a number of different steels used primarily for their resistance to corrosion. The one key element they all share is a certain minimum percentage (by mass) of chromium: 10.5%. Although other elements, particularly nickel and molybdenum, are added to improve corrosion resistance, chromium is always the deciding factor. The vast majority of steel produced in the world is carbon and alloy steel, with the more expensive stainless steels representing a small, but valuable niche market.
