Steel is considered to be low-alloy steel when either of the following conditions is met: • The maximum of the range given for the content of alloying elements exceeds one or more of the following limits: 1.65% Mn, 0.60% Si, and 0.60% Cu • Any definite range or definite minimum quantity of any of the following elements is specified or required within the limits of the recognized field of constructional alloy steels: aluminum, boron, chromium up to 3.99%, cobalt, niobium, molybdenum, nickel, titanium, tungsten, vanadium, zirconium, or any other alloying element added to obtain the desired alloying effect Alloying elements are added to hot-finished plates for various reasons, including improved corrosion resistance and/or improved mechanical properties at low or elevated temperatures. Alloying elements are also used to improve the hardenability of quenched and tempered plate. Low-alloy steels generally require additional care throughout their manufacture. They are more sensitive to thermal and mechanical operations, the control of which is complicated by the varying effects of different chemical compositions. To secure the most satisfactory results, consumers normally consult with steel producers regarding the working, machining, heat treating, or other operations to be employed in fabricating the steel; mechanical operations to be employed in fabricating the steel; mechanical properties to be obtained; and the conditions of service for which the finished articles are intended. The chemical composition requirements of standard low-alloy steel plate are listed in Table 3. These low-alloy steels may be suitable for some structural applications when furnished according to ASTM A 6 and A 829. The effect of residual alloying elements on the mechanical properties of hot-finished steel plate is discussed in the section "Mechanical Properties" in this article. The effect of alloying elements on the hardenability and mechanical properties of quenched and tempered steels is discussed in the articles "Hardenable Carbon and Low-Alloy Steels" and "High-Strength Structural and High-Strength Low-Alloy Steels" in this Volume. Table 3 Composition ranges and limits for AISI-SAE standard low- alloy steel plate applicable for structural applications Boron or lead can be added to these compositions. Small quantities of certain elements not required may be found. These elements are to be considered incidental and are accept able to the following maximum amounts: copper to 0.35%, nickel to 0.25%, chromium to 0.20%, and molybdenum to 0.06%.

For steels made by the electric furnace process, the ranges and limits are reduced as follows: C 0.01%; Mn 0.05%; Cr 0.05% (<1.25%), 0.10%(>1.25%); maximum content for either phosphorus or sulfur is 0.025%. (b) Other silicon ranges may be negotiated. Silicon is available in ranges of 0.10-0.20%, 0.20-0.30%, and 0.35% maximum (when carbon deoxidized) when so specified by the purchaser. (c) Prefix "E" indicates that the steel is made by the electric furnace process. (d) Contains 0.15% V minimum In addition to the low-alloy steels listed in Table 3, other low-alloy steel plates are also classified according to more specific requirements in various ASTM specifications. The chemical composition requirements and mechanical properties of low-alloy steel plate in ASTM standards are discussed in the section "Steel Plate Quality" in this article. High-strength low-alloy steels offer higher mechanical properties and, in certain of these steels, greater resistance to atmospheric corrosion than conventional carbon structural steels. The HSLA steels are generally produced with emphasis on mechanical property requirements rather than the chemical composition limits. They are not considered alloy steels as described in the American Iron and Steel Institute (AISI) steel products manuals, even though utilization of any intentionally added alloy content would technically qualify as such. There are two groups of compositions in this category: • Vanadium and/or niobium steels, with a manganese content generally not exceeding 1.35% maximum and with the addition of 0.2% minimum copper when specified • High-strength intermediate-mang anese steels, with a manganese content in the range of 1.10 to 1.65% and with the addition of 0.2% minimum copper when specified Other elements commonly added to HSLA steels to yield the desired properties include silicon, chromium, nickel, molybdenum, titanium, zirconium, boron, aluminum, and nitrogen. The chemical compositions of ASTM structural quality and pressure vessel quality plates made of HSLA steel are listed in Table 4. More information on HSLA steels is provided in the article "High-Strength Structural and High-Strength Low-Alloy Steels" in this Volume.

Steel Plate Quality Steel quality, as the term applies to steel plate, is indicative of many conditions, such as the degree of internal soundness, relative uniformity of mechanical properties and chemical composition, and relative freedom from injurious surface imperfections. The various types of steel plate quality are indicated in Table 1. The three main quality descriptors used to describe steel plate are regular quality, structural quality, and pressure vessel quality. Special qualities include cold-drawing quality, cold-pressing quality, cold-flanging quality, and forging quality carbon steel plate, along with drawing quality and aircraft quality alloy steel plate. Quality descriptors that have been used in the past include flange quality and firebox quality carbon and alloy steel plate and marine quality carbon steel plate. However, use of these descriptors has been discontinued in favor of pressure vessel quality. Regular quality is the most common quality of carbon steel, which is applicable to plates with a maximum carbon content of 0.33%. Plates of this quality are not expected to have the same degree of chemical uniformity, internal soundness, or freedom from surface imperfections that is associated with structural quality or pressure vessel quality plate. Regular quality is usually ordered to standard composition ranges and is not customarily produced to mechanical property requirements. Regular quality is analogous to merchant quality for bars because there are normally no restrictions on deoxidation, grain size, check analysis, or other metallurgical factors. Also, this quality plate can be satisfactorily used for applications similar to those of merchant quality bars, such as those involving mild cold bending, mild hot forming, punching, and welding for noncritical parts of machinery. Structural quality steel plate is intended for general structural applications such as bridges, buildings, transportation equipment, and machined parts. The various ASTM specifications for structural quality steel plate are given in Table 5. Most of the structural steel plate listed in Table 5 is furnished to both chemical composition limits (Table 6) and mechanical properties (Table 7). However, some structural steel plate (ASTM A 829 and A 830 in Table 5) is produced from the standard steels listed in Tables 2 and 3. These steels can be furnished only according to the chemical compositions specified by SAE/AISI steel designations. Factors affecting the mechanical properties of hot-finished carbon steel are discussed in the section "Mechanical Properties" in this article.
