Note 1 — Tolerances in this table apply to any length, not necessarily the rolling direction, up to 36 in. [914mm] and to any 36 in. [914mm] of longer lengths in the plane of the plate measured while the plate rests on a flat surface with the concavity of the curvature upward.

Note 2 — If the longer dimension is under 36 in. [914mm], the tolerance is not greater than 1/4 in. [6.4mm].

Note 3 — for plates with specified minimum yield strengths of 35 ksi [240MPa] or more, the permitted variations are increased to 1 1/2 times the amounts shown.

Tolerances to ISO 18286 for hot rolled stainless steel quarto plates

General

This standard covers hot rolled stainless steel plates rolled on a reversing mill known as quarto plate. It may also be taken to cover plate rolled on a Steckel mill but taken out of the process before coiling has begun.

For continously hot rolled plate (CPP), ISO 9444 is applicable.

It replaces EN 10029 which was not specifically for stainless steel. It removes some anomalies and ambiguities from that standard.

One interpretation of the standard is that no ground area of the plate may fall below the minimum thickness tolerance. This is in contrast to EN 10163 which was referred to in EN 10029 and allowed some areas to be below minimum thickness.

The 4 Classes of thickness tolerance (A-D) in EN 10029 have been replaced by one class which is similar to Class B - minimum tolerance of 0.3mm under nominal thickness.

There are no tolerances on the maximum difference allowed within a plate.

The flatness tolerance is dependent on grade.

Provision is made for different width and length tolerances depending on the method of cutting.

Thickness

The tolerance under nominal thickness is 0.3mm.

  1. It is not possible to make an exact comparison with EN 10029 as the thickness bands are different. However, the following comparison of some typical thicknesses gives an idea:
    Tolerances on thickness for typical plate sizes in EN 10029 and ISO 18286

    100 2000 +2.9 +2.95
    100 3000 +2.9 +3.35

    In general, wider plate has more generous tolerances than in EN 10029.

  2. For plates with trimmed edges, the thickness shall be measured at any point > 10mm and < 75mm from a longitudinal edge.

Width and length tolerance

There are 3 classes of tolerance for width and length for plates with trimmed edges A - C. This is dependent on the method of cutting the plates.

Class A - cutting method not specified. By implication includes shearing.

Class B - flame-cut plate. Probably intended to mean plasma.

Class C - abrasive cut plate. Probably intended to mean water-jet cutting.

There is no mention of other cutting methods such as laser.

Tolerances on mill edge plate shall be agreed at the time of enquiry and order.

  1. For plates of thickness > 100mm width and length tolerance for Class C must be agreed at the time of the enquiry and order.

 Edge camber and out of squareness

For plate with trimmed edges, the edge camber shall not exceed 0.5% of the nominal length of the plate. Out of squareness shall not exceed 1% of the nominal width of the plate. For comparison, EN 10029 has an edge camber of 0.2% and out of squareness of 1%.

For plate with untrimmed edges in the enquiry and in the purchase order, the edge camber and out of squareness shall be limited so that it is possible to inscribe a rectangle of the nominal length and width of the ordered plate within the delivered size. In EN 10029, the inscribed rectangle definition was not restricted to plates with untrimmed edges.

Flatness

There are two levels of tolerance normal (Class N) and special (Class S). The class shall be specified at the time of enquiry and order. If not specified, the manufacturer can supply to either class.

For both classes the tolerance is dependent on the steel type:

Type A - All grades not of type B

Type B - stainless steel grades with Ni > 20% OR Mo > 2% or N > 0.11%.

    Steel Type A - Maximum of 1% of the distance between the points of contact between > 300mm and < 1000mm.

    Steel Type B - Maximum of 1.5% of the distance between the points of contact between > 300mm and < 1000mm.

  1.  Unless otherwise specified, the measuring length is at the manufacturer's discretion.
  2. If the distance between the points of contact of the straight edge and plate is < 1000mm, the deviation shall comply with the following: 
    Maximum of 0.5% of the distance between the points of contact but not exceeding the values in the table for Class S. (By implication, this note applies to steel type A since for steel type B, tolerances are agreed at the time of enquiry and order. However, the standard is somewhat unclear. It is also not clear why the 300mm minimum length does not apply for class S as compared with class N).

It is quite difficult to compare the flatness tolerances in EN 10029 and ISO 18286, as the definition of steel types is totally different. In EN 10029 which was for all steels, steel types were L and H split by yield strength above and below 460 N/mm2. This meant that most stainless steels fell into steel type L. Even the nitrogen strengthened steels were in this type. Therefore, 304 and 316 were given the same flatness tolerance. The effect of the new standard is to put Mo and N bearing steels into the steel type B and therefore giving  less stringent flatness tolerances than previously.

An approximate comparison is shown in the following table for a 10mm plate in various grades of steel using the 2000mm measuring length:

Comparison of flatness Class N EN 10029 and ISO 18286
Steel grade Tolerance EN 10029 Tolerance ISO 18286
1.4003 (3CR12) 11 10
1.4028 (420) 14 10
1.4301 (304) 11 10
1.4362 (2304) 11 10/14? (N is 0.05/0.020%)
1.4401 (316) 11 14
1.4410 (2507) 14 14
1.4462 (2205) 14 14
1.4501 (Zeron 100) 14 14
1.4542 (17-4 PH) 14 11
1.4547 (254SMO) 11 14
1.4845 (310) 11 14

It can be argued that neither standard is completely consistent on this subject. For example, martensitic grades in the quench and tempered condition or high yield strength PH grades are expected to have a better flatness than 316. This may not be realistic.
