ASTM A793-96 (2014) PDF

Full title and description

ASTM A793 − 96 (Reapproved 2014) — Standard Specification for Rolled Floor Plate, Stainless Steel. Covers stainless‑steel floor plates (1/2 in. and under) in patterned designs for use in galley spaces, washrooms, engine rooms, machinery spaces, ladder treads, gun platforms, and deck treads; specifies permitted grades, patterns (A, B, C), dimensional and manufacturing requirements, mechanical tests, and magnetic permeability limits.

Abstract

This specification establishes the requirements for stainless steel rolled floor plate with raised figure patterns. It identifies acceptable alloy grades (examples include Type 304/304L and 316/316L), annealing as the final heat treatment, permitted patterns (A, B, C), dimensional/weight limits for flat‑ and hollow‑back plates, mechanical test requirements (including cold‑bend tests), and a magnetic‑permeability test criterion. The intent is to ensure material uniformity and suitability for tread/flooring applications.

General information

• Publication date: Current edition approved March 1, 2014 and published April 2014 (original designation A793 first approved in 1981; designation A793‑96 indicates original adoption year 1996).
• Publisher: ASTM International (ASTM).
• ICS / categories: 77.140.20 (Stainless steels) and 77.140.50 (Flat steel products and semi‑products).
• Edition / version: Designation A793 − 96 (Reapproved 2014) — often shown as A793‑96 (R2014).
• Number of pages: 4 pages (short technical specification).

Scope

The standard applies to stainless steel rolled floor plates having nominal thicknesses up to 1/2 inch intended for service as tread and deck plates in shipboard and industrial environments (galley, washroom, engine room, machinery spaces) and for ladder treads, gun platforms and deck treads. Patterns A, B and C are treated as interchangeable for these uses; the specification gives allowable dimensional, weight and raised‑figure characteristics and requires conformance to specified chemical, mechanical and magnetic permeability requirements.

Key topics and requirements

• Accepted material grades and chemical composition limits (examples include Type 304/304L and 316/316L listed by grade table).
• Pattern definitions and geometry for Patterns A, B and C (raised figure height, pitch and arrangement; flat back vs hollow back options).
• Dimensional and weight tolerances for thickness, width and length (tables of permissible variations by pattern and nominal weight).
• Manufacturing requirement that annealing is the last heat treatment applied prior to delivery.
• Mechanical tests including longitudinal cold‑bend tests that the raised figure must not fracture or crack.
• Magnetic permeability testing requirement (mu ≤ 1.20 with MIL‑I‑17214 indicator when specified) and lot/sample rules for permeability testing.
• Ordering information elements purchasers must specify (quantity, dimensions, grade, flat or hollow back, etc.).

Typical use and users

Used by shipbuilders, marine outfitters, industrial fabricators, flooring and tread manufacturers, procurement/specification engineers, maintenance planners, and standards/quality personnel specifying patterned stainless‑steel floor plates for anti‑slip, corrosion‑resistant flooring and tread applications in marine and industrial settings. Designers and buyers consult the standard to select pattern, grade and required tests for procurement.

Related standards

Commonly referenced/related documents include ASTM A480/A480M (General requirements for flat‑rolled stainless and heat‑resisting steel), ASTM A370 (Mechanical testing of steel products), ASTM A340 (Terminology for magnetic testing), and military indicators such as MIL‑I‑17214 for permeability (referenced for the low‑mu go/no‑go indicator). Users often consult these standards when ordering, testing or verifying floor plate material.

FAQ

Q: What is this standard?

A: ASTM A793 is a short ASTM specification that defined the requirements for rolled stainless‑steel floor (tread) plate in patterned designs for industrial and marine use; the designation in circulation is A793‑96 (reapproved 2014).

Q: What does it cover?

A: It covers stainless‑steel floor plates up to 1/2 in. thick, the three raised‑figure patterns (A, B, C), allowable dimensions/weights, required chemical and mechanical properties, annealing practice, and magnetic‑permeability acceptance criteria; it also sets sampling and test requirements.

Q: Who typically uses it?

A: Shipbuilders, marine equipment suppliers, industrial fabricators, specifiers, purchasing organizations, and QA/test labs use the standard to specify and verify patterned stainless‑steel floor plate.

Q: Is it current or superseded?

A: ASTM A793‑96 (R2014) was withdrawn by ASTM in 2023; the ASTM store lists the document as “Standard Withdrawn, No replacement.” Users should confirm current procurement and regulatory requirements and consult ASTM or relevant authorities for any successor documents or applicable product specifications.

Q: Is it part of a series?

A: It is part of ASTM Committee A01 outputs on steel and stainless steel (developed under Subcommittee A01.17 on flat‑rolled and wrought stainless steel) and is cross‑referenced with other ASTM standards governing stainless‑steel flat products and testing (for example A480/A480M, A370).

Q: What are the key keywords?

A: Rolled floor plate, patterned stainless steel, tread plate, Pattern A/B/C, magnetic permeability, cold bend, flat back, hollow back, ASTM A793.
