Applications. Both 1018 and 1020 grade steel can be made in their cold drawn or hot rolled forms, however most 1020 steel comes in a turned and polished or cold drawn condition. In its cold drawn state, 1020 has high machinability and is a preferred steel grade for many manufacturers. 1018 steel is used over 1020 for applicationsbest 1020 steel hardness
RE: Hardness of 1020 case hardnening unclesyd (Materials) 18 Aug 11 08:43 My Bethlehem Steel data book for a .505 round bar gives a case depth of 0.065 a hardness of Rc 61 and a core hardness of 20 Rc.
AISI 1020 has low hardenability properties and is a low tensile carbon steel with a Brinell hardness of 119 235, and a tensile strength of 410-790 MPa. It has high machinability, high strength, high ductility and good weldability.
Looks like you need a durometer, not that expensive, the hardness difference is fairly wide, so it should show up easily. 1045 should be around 179, 1020 should be around 130 or so. test the incoming batches against the matcerts and hold anything that doesn't match.

The following data shows that AISI SAE 1020 steel mechanical properties include yield strength, tensile strength, elongation, section reduction, and hardness in various conditions. SAE AISI 1020 steel Youngs modulus (modulus of elasticity) in the as-received condition: 186 GPa (2710 6 psi).
Introduction. Carbon steels is a category of steel, which contains 0.12 to 2% carbon. This steel category gains hardness and strength with heat treatment when the percentage of carbon content increases but the ductility is reduced. AISI 1020 carbon steel is a commonly used plain carbon steel.
SAE AISI 4140 Alloy Steel. SAE 4140 (AISI 4140 steel) is a Cr-Mo series (Chrome molybdenum series) low alloy steel, this material has high strength and hardenability, good toughness, small deformation during quenching, high creep strength and long-lasting strength at high temperature.

Stainless Steel, Special Steel, Compressor Blading, Turbine Blading, Superalloy Supplier. SAE 1020 can be supplied as steel plate/ sheet, round steel bar, steel tube/pipe, steel stripe, steel billet, steel ingot, steel wire rods. electroslag, forged ring/ block,etc.
The tensile strength of 1020 steel bars typically ranges from 410 to 790 Mpa. Tensile strength is the maximum stress a material can withstand without tearing. The steel has a Brinell hardness range of 119 to 235.
1020 is a general purpose low tensile low hardenability carbon steel generally supplied in the cold drawn or turned and polished condition, with a typical tensile strength range 410 - 790 Mpa, and Brinell hardness range 119 - 235. Characterised by excellent weldability, very good machinability with reasonable strength and very good ductility.

1045 Medium carbon steel. often used for bolts, studs and shaft parts. High strength and hardness. Hot Rolled Carbon Steel. 1018, 1020 (HR,CF) - Low carbon steel. Has good hardening properties, fair machinability. Readily brazed and welded. 1117 (HR,CF) - Low carbon, high manganese steel. Good machinability, case hardening is deep and uniform.
AISI 1020 Steel, as rolled Categories: Metal; Ferrous Metal; Carbon Steel; AISI 1000 Series Steel; Low Carbon Steel. Material Notes: Applications include parts in the case hardened condition where core strength is not critical, and for shafts of larger cross section that are not highly stressed.
You can only carburize and case harden 1020 steel. It is designed for easy fabrication, forming, and welding but does lend itself to be a hardened steel. It is considered a general purpose steel.
Dont worrywere going to break down and compare all the best knife steels you can expect to find at Blade HQ so that you can determine the supreme steel for your needs. Give this article and each knife steel chart a gander, and youll be halfway to an Ivy League degree as a metallurgist (no uhhnot really, but we all start somewhere).
Heat treater's can be brutal and ding's are common. If you have long parts make sure and state on the drawing and P.O. that the parts are to be racked vertically. Also call-out a straightness spec. ie: Parts to be straight to .005" after heat treat. You should also specify a core hardness usually 35 to 40 Rc.
1020 bright carbon steel bar 1020 is a general purpose low tensile low hardenability carbon steel generally supplied in the cold drawn or turned and polished condition, with a typical tensile strength range 410 - 790 Mpa, and Brinell hardness range 119 - 235.
AISI 1020 Steel is low hardenability and low tensile carbon steel carbon steel. And its Brinell hardness of 119 235 and tensile strength of 410-790 MPa. It is normally used in turned and polished or cold drawn condition. AISI 1020 steel ( JIS S20C steel) is resistant to induction hardening or flame hardening due to its low carbon content.
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.
Both ASTM A36 carbon steel and SAE-AISI 1020 steel are iron alloys. Their average alloy composition is basically identical. There are 31 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.
Carbon is present in all steel and is the principal hardening element, determining the level of hardness or strength attainable by quenching. It raises tensile strength, hardness, and resistance to wear and abrasion as the carbon content of steel is increased.
1020 steel responds well to cold work and heat treating. Weldability is fair. Applications: Shafts, lightly stressed gears, hard wearing surfaces, pins, chains and case hardened parts where core strength is not critical. 1020 is suitable for case hardened parts where core strength is not critical. Key Words:
hardness of AISI 1020 steel can be changed and improved by different heat treatments for a particular application. From the microstructures we have found that the annealed specimens with mainly ferrite structure give the lowest hardness value and highest ductility while hardened specimens which comprise
