And furthermore, A36 is considered a mild steel due to its relatively moderate hardness. In addition, A-36 is a structural-quality mild carbon steel used in general construction applications, including bolted or welded construction of buildings, bridges and common machine parts to name a few.
Hardness, Brinell : 119 - 159: 119 - 159: based on conversion from tensile strength: Hardness, Rockwell B : 67.0 - 83.0: 67.0 - 83.0: based on conversion from tensile strength: Tensile Strength at Break : 400 - 552 MPa: 58000 - 80000 psi: Tensile Strength, Yield >= 221 MPa >= 32000 psi: Elongation at Break >= 18.0 % >= 18.0 %: in 8" >= 21.0 % >= 21.0 %: in 2", > 24" W
If a suitable Rockwell scale is not possible due to not meeting minimum thickness requirements, the material may be tested on either the Knoop or Vickers Microhardness scales. Many Rockwell hardness blocks are available on the Quick Ship program.
Brinell Hardness 137 137 121 Machinability: 78% of B1112. Weldability: Easily welded by all welding processes, and the resultant welds and joints are of extremely high quality. Grade of welding rod used depends on welding conditions such as thickness of section, design, service requirements,
US $500-1200 / Metric Ton. There are 163 a36 hot rolled steel plate hardness suppliers, mainly located in Asia. The top supplying country is China (Mainland), which supply 100% of a36 hot rolled steel plate hardness respectively. A36 hot rolled steel plate hardness products are most popular in Southeast Asia, Mid East, and Africa.
Rockwell Minimum Thickness - Reference Information and Standards - Minmum thickness is one of the frequently overlooked aspects of hardness testing. As a rule users need to maintain a sample thickness at least ten times the maximum depth of indentation unless it is known that a material with a thinner thickness will provide the same result.
Consider that one regular Rockwell hardness number represents a vertical movement of the penetrator of approximately 80 millionths of an inch (0.000080 inch) and one superficial Rockwell number approximately 40 millionths of an inch (0.000040 inch).
A36 is low carbon (comparatively) because of this precipitation hardening is not going to happen.. Untempered martensite is possible (although uncommon) as exemplified by arc strikes, where rapid quenching can leave a small embrittled area. It can also be carburized (case hardened) There are a million search links that give various techniques, a36 steel rockwell hardness thickness
Thickness. Tolerance under specified thickness .010" x 3/4 x 52" wide plate, for example, would have a tolerance range of .740-.780". Because of tolerances, ie thickness, flatness and camber, as well as the hot roll condition, ASTM A36 generally does not finish to specified thickness.
Bethlehem Steel ASTM A36, >4 to 8 in. thick, as-rolled steel plate (discontinued **) Categories: Metal; Ferrous Metal; ASTM Steel; Carbon Steel; Low Carbon Steel. Material Notes: A popular "workhorse" grade, it is used widely for various applications. Information provided by Bethlehem Steel Corporation Data published in 1997.

testing equipment. Unlike Rockwell scales, microhardness numbers are affected by the applied load. For example, a Knoop hardness value of 100 taken with a 500-gram load (HKN500 100) is not equivalent to a Knoop hardness value of 100 taken with a 50-gram load (HKN 50 100). Hence it is critical to report the applied load along with the test result.

Steel Hardness Conversion Table. This table shows approximate hardness of steel using Brinell, Rockwell B and C and Vickers scales. These conversion charts are provided for guidance only as each scales uses different methods of measuring hardness. The right hand column show an approximate equivalent tensile strength.
The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measuring the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). There are different scales, denoted by a single letter, that use different loads or indenters.

4.1 The Rockwell hardness test is an empirical indentation hardness test that can provide useful information about metallic materials. This information may correlate to tensile strength, wear resistance, ductility, and other physical characteristics of metallic materials, and may be useful in quality control and selection of materials.
ASTM A36 steel is the most commonly available of the hot-rolled steels. It is generally available in round rod, square bar, rectangle bar, as well as steel shapes such as I-Beams, H-beams, angles, and channels. The hot roll process means that the surface on this steel will be somewhat rough.

Chemically, it is very similar to A36 Hot Rolled steel, but the cold rolling process creates a better surface finish and better properties. 1018 Mild (low-carbon) steel Ultimate Tensile Strength, psi 63,800 Yield Strength, psi 53,700 Elongation 15.0% Minimum Properties Rockwell Hardness B71
Hot Rolled Steel Plate A36 (0.1875") is made of low carbon steel that is commonly found in most industries as it offers good weldability, machinability, and can be heat treated to harden its surface. Unlike cold rolled steel, Hot Rolled Steel Plate A36 has a rougher surface and with galvanization, it can resist corrosion well.
