  1. Introduction to Stainless Steel

    Stainless steels are corrosion resistant steels with a minimum of 10.5 per cent of chromium, (Cr). The family or type terms ferritic, martensitic, austenitic and duplex are introduced. The main property of stainless steels, their corrosion resistance, is outlined. The affect of chromium, nickel and molybdenum on corrosion resistance is mentioned. Other useful properties of stainless steels, such as their high, (oxidation resistance), and low, (cryogenic), temperature resistance and work hardening are also mentioned. Welding, brazing and soldering as joining methods are also described briefly. A short list of example grades, such as 1.4016, (430S17), 1.4512, (409S19), ferritics, 1.4028, (420S45), martensitic, 1.4362, 1.4462, (2205), duplex, 1.4301, (304), 1.4307, (304S11), 1.4404, (316S31), 1.4541, (321S31), 1.4539, (904L) and 1.4547, (6% Mo) are also shown.

  2. Martensitic Stainless Steels

    Martensitic stainless steels are magnetic. Their main alloying elements are chromium, (typically 18%), and carbon, They are used for strength and moderate corrosion resistance. Examples of martensitic grades are 410, 410S21, (1.4006), 420, 420S29, (1.4021), 431, 431S29, (1.4057) and 440C, (1.4125).

  3. Matrices of European (EN) & ISO Standards for Stainless Steels

    EN standards covering materials, designations, inspection and dimensions, (tolerances), testing and certification are shown in a single table. There is a similar table for international ISO standards.

  4. 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.

  5. NACE MR 0175/ISO 15156 for Corrosion Resistant Alloys for Sulphide Service

    The NACE MR0175 standard for sulfide, (sulphide), stress corrosion cracking resistant metallic materials for oilfield equipment is now also available as an ISO standard 15156. This article summarises the requirements for all types of stainless steel austenitic , ferritic, duplex, martensitic and precipitation hardening stainless steels which are covered by the standard. Mill softened material will normally be found to comply with the requirements.
