Designation³

1.10 Additional requirements that are specified in the pur-

chase order and accepted by the supplier are permitted,

provided that such requirements do not negate any of the

requirements of this general requirements specification or the

applicable product specification.

1.11 For purposes of determining conformance with this

general requirements specification and the applicable product

specification,values are to be rounded to the nearest unit in the

right-hand place of figures used in expressing the limiting

values in accordance with the rounding method of Practice

E29.

1.12 The text of this general requirements specification

contains notes or footnotes,or both,that provide explanatory

material.Such notes and footnotes,excluding those in tables

and figures,do not contain any mandatory requirements.

1.13 The values stated in either inch-pound units or SI units

are to be regarded separately as standard.Within the text,the

SI units are shown in brackets.The values stated in each

system are not exact equivalents;therefore,each system is to

be used independently of the other,without combining values

in any way.

1.14 This general requirements specification and the appli-

cable product specification are expressed in both inch-pound

units and SI units;however,unless the order specifies the

applicable “M”specification designation(SI units),the struc-

tural product is furnished to inch-pound units.

1.15 This standard does not purport to address all of the

safety concerns,if any,associated with its use.It is the

responsibility of the user of this standard to establish appro-

priate safety and health practices and determine the applica-

bility of regulatory limitations prior to use.

3.Terminology

3.1 Definitions of Terms Specific to This Standard:

3.1.1 Plates (other than floor plates)—Flat,hot-rolled steel,

ordered to thickness or weight [mass]and typically width and

length,commonly classified as follows:

3.1.1.1 When Ordered to Thickness:

(1)Over 8 in.[200 mm]in width and 0.230 in.[6mm]or

over in thickness.

(2)Over 48 in.[1200 mm]in width and 0.180 in.[4.5 mm]

or over in thickness.

3.1.1.2 When Ordered to Weight [Mass]:

(1)Over 8 in.[200 mm]in width and 9.392 Ib/ft²[47.10

kg/m²]or heavier.

(2)Over 48 in.[1200 mm]in width and 7.3501b/ft²[35.32

kg/m²]or heavier.

3.1.1.3 Discussion—Steel products are available in various

thickness,width,and length combinations depending upon

equipment and processing capabilities of various manufactur-

ers and processors.Historic limitations of a product based upon

dimensions(thickness,width,and length)do not take into

account current production and processing capabilities.To

qualify any product to a particular product specification re-

quires all appropriate and necessary tests be performed and that

the results meet the limits prescribed in that product specifi-

cation.If the necessary tests required by a product specification

cannot be conducted,the product cannot be qualified to that

specification.This general requirement standard contains per-

mitted variations for the commonly available sizes.Permitted

variations for other sizes are subject to agreement between the

customer and the manufacturer or processor,whichever is

applicable.

3.1.1.4 Slabs,sheet bars,and skelp,though frequently

falling in the foregoing size ranges,are not classed as plates.

3.1.1.5 Coils are excluded from qualification to the appli-

cable product specification until they are decoiled,leveled or

straightened,formed (if applicable),cut to length,and,if

required,properly tested by the processor in accordance with

ASTM specification requirements(see Sections 9-15,18,and

19 and the applicable product specification).

3.1.2 Shapes(Flanged Sections):

3.1.2.1 structural-size shapes—rolled flanged sections hav-

ing at least one dimension of the cross section 3 in.[75 mm]or

greater.

3.1.2.2 bar-size shapes—rolled flanged sections having a

maximum dimension of the cross section less than 3 in.[75

mm].

3.1.2.3“W”shapes—doubly-symmetric,wide-flange

shapes with inside flange surfaces that are substantially paral-

lel.

3.1.2.4“HP”shapes—are wide-flange shapes generally

used as bearing piles whose flanges and webs are of the same

nominal thickness and whose depth and width are essentially

the same.

3.1.2.5“S”shapes—doubly-symmetric beam shapes with

inside flange surfaces that have a slope of approximately 162/3

%.

3.1.2.6“M”shapes—doubly-symmetric shapes that cannot

be classified as “W,”"S,"or “HP”shapes.

3.1.2.7“C”shapes—channels with inside flange surfaces

that have a slope of approximately 162/3 %.

3.1.2.8“MC”shapes—channels that cannot be classified as

“C”shapes.

3.1.2.9“L”shapes—shapes having equal-leg and unequal-

leg angles.

3.1.3 sheet piling—rolled steel sections that are capable of

being interlocked,forming a continuous wall when individual

pieces are driven side by side.

3.1.4 bars—rounds,squares,and hexagons,of all sizes;flats

13/64 in.(0.203 in.)and over [over 5 mm]in specified thickness,

not over 6 in.[150 mm]in specified width;and flats 0.230 in.

and over [over 6 mm]in specified thickness,over 6 to 8 in.

[150 to 200 mm]inclusive,in specified width.

3.1.5 exclusive—when used in relation to ranges,as for

ranges of thickness in the tables of permissible variations in

dimensions,is intended to exclude only the greater value of the

range.Thus,a range from 60 to 72 in.[1500 to 1800 mm]

exclusive includes 60 in.[1500 mm],but does not include 72

in.[1800 mm].

3.1.6 rimmed steel—steel containing sufficient oxygen to

give a continuous evolution of carbon monoxide during

soldification,resulting in a case or rim of metal virtually free of

voids.

3.1.7 semi-killed steel—incompletely deoxidized steel con-

taining sufficient oxygen to form enough carbon monoxide

during solidification to offset solidification shrinkage.

3.1.8 capped steel—rimmed steel in which the rimming

action is limited by an early capping operation.Capping is

carried out mechanically by using a heavy metal cap on a

bottle-top mold or chemically by an addition of aluminum or

ferrosilicon to the top of the molten steel in an open-top mold.

3.1.9 killed steel—steel deoxidized,either by addition of

strong deoxidizing agents or by vacuum treatment,to reduce

the oxygen content to such a level that no reaction occurs

between carbon and oxygen during solidification.

3.1.10 mill edge—the normal edge produced by rolling

between horizontal finishing rolls.A mill edge does not

conform to any definite contour.Mill edge plates have two mill

edges and two trimmed edges.

3.1.11 universal mill edge—the normal edge produced by

rolling between horizontal and vertical finishing rolls.Univer-

sal mill plates,sometimes designated UM Plates,have two

universal mill edges and two trimmed edges.

3.1.12 sheared edge—the normal edge produced by shear-

ing.Sheared edge plates are trimmed on all edges.

3.1.13 gas cut edge—the edge produced by gas flame

cutting.

3.1.14 special cut edge—usually the edge produced by gas

flame cutting involving special practices such as pre-heating or

post-heating,or both,in order to minimize stresses,avoid

thermal cracking and reduce the hardness of the gas cut edge.

In special instances,special cut edge is used to designate an

edge produced by machining.

3.1.15 sketch—when used to describe a form of plate,

denotes a plate other than rectangular,circular,or semi-

circular.

3.1.16 normalizing—a heat treating process in which a steel

plate is reheated to a uniform temperature above the upper

critical temperature and then cooled in air to below the

transformation range.

3.1.17 plate-as-rolled—when used in relation to the location

and number of tests,the term refers to the unit plate rolled from

a slab or directly from an ingot.It does not refer to the

condition of the plate.

3.1.18 fine grain practice—a steelmaking practice that is

intended to produce a killed steel that is capable of meeting the

requirements for fine austenitic grain size.

3.1.18.1 Discussion—It normally involves the addition of

one or more austenitic grain refining elements in amounts that

have been established by the steel producer as being sufficient.

Austenitic grain refining elements include,but are not limited

to,aluminum,columbium,titanium,and vanadium.

3.1.19 structural product—a hot-rolled steel plate,shape,

sheet piling,or bar.
