1. Although it does not say so in the standard, the first item is the weight or number of pieces required e.g. 100 sheets or 3 tonnes.
2. Type of product means: – wide strip, slit strip, plates, sheet or cut lengths.
3. Next comes the number of this standard – EN 10259.
4. Next is the nominal thickness in mm remembering that thickness tolerances given in table 1 are equally +/-.
5. If special thickness tolerances are required, on material less than 2mm thick, indicate this using “S”, otherwise the material will be supplied to normal thickness tolerances.
6. The nominal width in mm is next, remembering that all width tolerances are positive, unless specially agreed otherwise.
7. If special width tolerances are required, on material no wider than 600mm, indicate this using “S” after the width, otherwise normal width tolerances will be used.
8. For plates, sheets and cut lengths, next put the nominal length in mm, remembering that all length tolerances are positive.
9. If special length tolerances are required indicate this using “S”, otherwise normal length tolerances will be used.
10. If special flatness tolerances are required, as described in clause 10, indicate this using “FS”, otherwise normal tolerance will be supplied.
11. Finally, add any extra dimensional requirements, before describing the steel grade and finish, certification and any other technical requirements. It is suggested that the EN 10088 steel number be used, rather than the name, when ordering, as this is more widely used & understood.

An example of the ‘order’ format is:

10 tonnes of wide strip EN 10259 – 1,20×1250
Steel EN 10088-2 – 1.4301+2B

for specifying 10 tonnes of wide strip, with nominal thickness 1.20mm and normal thickness tolerance, nominal width 1250mm in steel with name X5CrNi18-10 and number 1.4301 and process route 2B, all as specified in EN 10088-2.

European product standards to which EN 10259 can be applied

EN 10259 can be applied to the following existing and proposed product standards:

General purposes product standards

EN 10088-2:2005 Stainless steel. Technical delivery conditions for sheet/plate and strip of corrosion resisting steels for general purposes

EN 10095:1999 Heat resisting steels and nickel alloys

Pressure purposes product standards

EN 10028-1:1993 Specification for flat products made of steels for pressure purposes. General requirements

EN 10028-7:2000 Specification for flat products made of steels for pressure purposes. Stainless steel

Martensitic Stainless Steel

Martensitic stainless steel are similar to low alloy or carbon steels. They have a structure similar to the ferritics with a ‘body-centred tetragonal’ (bct) crystal lattice. Due to the addition of carbon, they can be hardened and strengthened by heat treatment, in a similar way to carbon steel. They are classed as a “hard” ferro-magnetic group. The main alloying element is chromium, with a typical content of 12-15%.

In the annealed condition, they have tensile strength and yield strength of about 275 Mpa and so they are usually machined, cold formed, or cold worked in this condition. The strength obtained by heat treatment depends on the carbon content of the alloy. Increasing the carbon content increases the strength and hardness potential but decreases ductility and toughness. The higher carbon grades are capable of being heat treated to hardnesses of 60 HRC.

Optimum corrosion resistance is attained in the heat-treated i.e. hardened and tempered condition. Martensitic grades have been developed with nitrogen and nickel additions but with lower carbon levels than the traditional grades. These steels have improved toughness, weldability and corrosion resistance

Examples of martensitic grades are (420S45) 1.4028, 431 (1.4057) as traditional carbon hardenable grades and 248SV (1.4418) as one of the low carbon / nitrogen grades.
