EN Standards for Stainless Steel H.R. Plate


For Hot Rolled stainless steel the old BS1449 and BS1501 standards have been replaced by EN Standards:

EN10088-2 Replaces BS1449-Part 2: 1983

EN10028-7 Replaces BS1501-Part3: 1990

EN10095 Covers Heat Resisting Grades

EN10259 & ISO 9445: Tolerances for COLD Rolled material (Sheets, plate, coil) up to 6.5mm thick

EN10029 & ISO 18286: Tolerances for 'Quarto' Hot Rolled Plate 3mm thick and above

EN10051 & Now ISO 9445 / 9444: Tolerances for Continuosly Produced (CPP) Hot Rolled Plate

Flatness - CPP

For CPP there are 3 categories of tolerances according to the grade where:

B = Ferritic and Martensitic Grades

C = Austenitic Grades without Mo

D = Austenitic Grades with Mo

* These flatness tolerances only apply for thicknesses up to 25mm

** To be agreed at the time of enquiry and order

These figures must be increased for stainless steel by:

15% for Ferritic & Martensitic

30% for Austenitic

40% for Moly Grades

Tolerances

For Cold Rolled Plate please refer to the datasheet on cold rolled

 

Note that in this Datasheet there are two sets of tolerances tables – One set for Quarto Plate to EN10029 and one set for CPP plate to EN10051

 

For CPP there are 3 categories of tolerances according to the grade where:

B = Ferritic & Martensitic Grades

C = Austenitic Grades without Mo

D = Austenitic Grades with Mo

Material Certification

Where multi-certification is required, a combination of EN10088-2, EN10028-7, EN10029 or 10051 will appear together with the appropriate ASTM Standards.
