The prehardened condition is heat treated to a medium hardness (HRC 28/32) and is designated as 4140 HT. 4140 annealed is supplied in the soft condition and can be hardened to RC 54. 4140 annealed is designated as 4140 Ann or simply 4140. 4140 HT is supplied in many forms such as hot rolled or turned, ground and
4140 Hot Rolled SBQ Bar. Hot rolled 4140 steel bar is a medium-carbon alloy steel that has a high hardenability. This grade is also widely used for forging. Hot rolled 4140 steel also has good fatigue and impact resistance after heat treating. Eaton Steel Bar Company stocks various diameters of 4140 hot rolled steel to meet the market demands. 4140 Pre Hard - BICO Steel Service Centers4140PH is a chromium-manganese-molybdenum grade This grade is delivered in a prehardened condition at a hardness level of 33/37HRC The grade has a fully homogeneous martensite- bainite microstructure 4140PH grade has specific sulfur addition (0.060% typical) in order to 4140 hardness chart - gnyu.volkswagensvaplus.itBrinell 3000kg Load 10mm Ball Rockwell Approx Tensile Strength, psi; Diameter, mm Hardness Number B Scale C Scale; 2.25:745 65.3 2.3:712 2.35 4140 Steel Annealing Slowly heat to 8008500 ºC, keep enough time, ensure heat thoroughly. then cooling in furnace to 480 ºC , then cool in air.
AISI 4140 Steel, annealed at 815°C (1500°F) furnace cooled 11°C (20°F)/hour to 665°C (1230°F), air cooled, 25 mm (1 in.) round Categories: All About 4130 Steel (Properties, Strength, and Uses)Dec 05, 2020 · There are three main scales (A, B, & C), where the Rockwell B hardness scale value is depicted in Table 1. For reference, the Rockwell B hardness of copper, a relatively soft metal, is 51. Type 4130 steel has a Rockwell hardness of 92, which is high for steel Alloy Steel 4140 Alloys International, Inc.AISI 4140 steel is a low alloy steel containing chromium, molybdenum, and manganese. It is widely used across numerous industries and is an excellent material choice due to its toughness, high fatigue strength, and abrasion and impact resistance. Not many grades can match the versatility and usefulness of 4140.

I cant find any data which specifies the hardness of a Grade 8 bolt for a comparison. I've seen specs that say core hardness is 33-39 Rockwell C for Grade 8 in sizes 1/4" - 1 1/2". 02-13-2007, 04:18 PM #4. gbent
