The heat ability reates very good welding properties, and the 36 ksi yield strength makes ASTM A36 steel plate acceptable for most applications. A36 is considered a mild steel due to its relatively moderate hardness. BHN - Brinell Hardness NumberThe diameter of the resulting permanent impression in the tested metal is measured and the Brinell Hardness Number calculated as. BHN = 2 P / ( D (D - (D 2 - d 2) 1/2)) (1) where . BHN = Brinell Hardness Number. P = load on the indenting tool (kg) D = diameter of steel ball (mm)

Below are yield, tensile and elongation measurements for two common grades of steel:A36 mild steel and A572-50 high strength low alloy structural steel. The data show that A572-50 can bear a greater load than A36, but A36 is more ductile. Estimating Welding Preheat Requirements for Unknown A36 and ASTM 616 Grade 60 billets had 5-in. square cross sections. These billet a Rockwell hardness tester. Rockwell A hardness was measured using a 60-kg load with a diamond Brale indenter to produce tent in a steel, the more difficult the steel is to weld, especially at ambient tempera-
Combining strength with weldability and formability, A572 alloy steel is an economical choice for structural components, such as channels, beams, and framing. It has a low carbon content, making it easy to weld with a variety of welding methods. Stronger than other low-carbon steels, such as A36 steel, it handles heavy loads without fracturing. Tested using ASTM A572, these sheets and bars are Hot Rolled Steel A36 (44W in Canada) Metal Supermarkets Grade Summary:ASTM A36 is is the most commonly available of the hot-rolled steels which has good overall mechanical properties, is easily fabricated and may be formed hot or cold. Due to the hot roll process the surface on this steel will be rough when compared to cold rolled. ASTM A36 yield strength is also less than C1018. Limitations of Hardness Testing for Deep Drawing The Rockwell hardness calculation defines the difference between this depth reading and the reference depth as d in the equation for the Rockwell B scale:HRB = 130 (d / 0.002 mm) Per this equation, a hardness measurement of HRB 80 means that the indenter penetrated 0.10 mm into the metal, and 0.13-mm penetration occurrs on a metal

Dear Gislain; several years ago we have something similar, but it was A36, in a building. It seems to me, that unless there is Carbon pick up, you will have the same hardness. PRACTICAL HARDNESS TESTING MADE SIMPLE if the tested material is too hard (more than 450 HBS for steel ball or more than 650 HBW for tungsten carbide ball). The letters HBS stand for Hardness Brinell with Steel ball, (HBW for tungsten carbide ball) but the qualification should be completed by indicating also the ball diameter (10 mm) and the applied force (load) (3000 kg).
Rockwell hardness is determined using an apparatus called the Rockwell hardness tester as shown in Fig. 5.5.A standard specimen of 0.25 in. (6.35 mm) minimum thickness is used. The specimen can be either molded or cut from a plastic sheet. The Effect of Agitation Parameter on Hardness and The results showed that the faster the rpm, the more hardness was obtained which increased and the thickness of the layer increased. The highest hardness and thickness values are found at a rotational speed of 132 rpm. With a hardness value of 77.5 VHN and a thickness value of 4.55 µm (Nickel) and 13.76 µm (Chrome). US ASTM AISI and SAE Standards - Page 3 of 4 - The World ASTM A36 Steel ASTM A36 steel is one of the most widely used carbon structural steels, although the carbon content of A36 material is maximum 0.29%, it is considered to be the mild steel (content of
