This specification covers the standard for stainless steel floor plates for use in galley spaces, washrooms, engine rooms, and machinery spaces, and for ladder treads, gun platforms, and deck treads. Several steel grades like Type 304, 304L, 316, 316L used as floor plate material shall conform to the chemical composition requirements in carbon, manganese, phosphorus, sulfur, silicon, nitrogen, nickel, chromium, and molybdenum as determined by heat analysis. Annealing shall be the last heat treatment to which the material is subjected. The stainless steel floor plate shall be in patterns with uniform pitch from center to center, angular figures shall be arranged such that they are in angular position from a vertical or horizontal line and shall have a raised figure. Mechanical properties shall be tested by two longitudinal cold bend tests and the raised figure shall not fracture nor develop cracks or flaws on the materials. Magnetic permeability test shall also be performed on the plates and shall meet the specified magnetic permeability indicator. Floor plates of stainless steel shall be uniform in quality and condition, and free of injurious defects that may detrimentally affect the suitability for the service for which they are intended.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers stainless steel floor plates ½ in. and under for use in galley spaces, washrooms, engine rooms, and machinery spaces, and for ladder treads, gun platforms, and deck treads. For these uses, Patterns A, B, and C are considered interchangeable (see Fig. 1, Fig. 2, and Fig. 3).

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

FIG. 1 Pattern A (percent of reduction, 61 %)

FIG. 2 Pattern B (original of raised figures approximately 1¼ in., percent of reduction 61 %)

FIG. 3 Pattern C
