With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
Introduction. AISI 1020 is a low hardenability and low tensile carbon steel with Brinell hardness of 119 235 and tensile strength of 410-790 MPa. It has high machinability, high strength, high ductility and good weldability. It is normally used in turned and polished or cold drawn condition.
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 rc
T10 Tool Steel is a Tungsten alloy steel with a very high carbon content (around 0.9 to 1.0%) with a little bit of silicon (around .35% maximum) and is often referred to as 'High Speed Steel'.
RE: Hardness of 1020 case hardnening. 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. Using the approximate conversions given in the Uconeer software linked below gives an 82 Ra hardness for the case. These numbers agree with my American Chain and Cable Handbook.
1020 is a commonly used plain carbon steel. It has a nominal carbon content of 0.20% with approximately 0.50% manganese. It has a good combination of strength and ductility and may be hardened and carburized. Used for simple structural applications such as cold formed fasteners and bolts.
Thread: Case hardening 1018 or 1020. One of my typical parts is made of 12L14 (leaded mild steel) with a blind hole tapped 10-32 to a depth of .750". The holes come out fine with no scaling. Try that without a controlled atmosphere. IMO, amateur heat treating ain't worth the time, effort and risk of ruining the parts.
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.
There may be no difference at all. In structural steel, 44W is a perfornamce rating (minimum yield strength 44,000psi). 1020 is steel chemistry (non-alloyed steel with 2.0% carbon).
1018 vs. 1045 Steel Comparison Carbon steel is one of the most widely used materials in the world, and the 1018 and 1045 grades of steel is a big reason for that. One of the most common questions that arise when considering buying cold finished steel products is the difference between 1018 cold steel bars and 1045 cold bars.
Carbon steels are those that have carbon as the main alloying element. They also contain up to 0.4% silicon and 1.2% manganese. In addition, the residual elements such as copper, molybdenum, aluminium, chromium and nickel are present in these steels. The AISI 1030 steel is a high carbon steel, and best 1020 steel rc
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:
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.
C1018 is a general purpose low carbon steel with good case hardening qualities. It has a higher manganese content than certain other low carbon grades, such as 1020. With higher manganese, 1018 is better steel for carburized parts, since it produces a harder and more uniform case.
In structural steel, 44W is a perfornamce rating (minimum yield strength 44,000psi). 1020 is steel chemistry (non-alloyed steel with 2.0% carbon). Quite often 44W is 1018 (1.8% carbon) or 1020 in best 1020 steel rc

C1050 is a versatile medium carbon engineering steel that can be through hardened to a little over 2.5 (63mm), as well as being flame or induction hardened to Rc61. All Metals & Forge Group is an ISO 9001:2008, AS/EN9100:2009 Rev. C manufacturer of open die forgings and seamless rolled rings.
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).
DI Rc 35 and Rc 45 DI Rc 55 Q&T Steel Rc 55 Hardenability The starting grade or microstructures of any Dura-Bar products have little relationship to their ability to be hardened.

Common to all types of steel is carbon, which can be found in varying quantities, depending upon the intended use of the steel being processed. Properties of 1095 Steel. 1095 Steel is a basic form of carbon steel and is most commonly used in the construction of various kinds of knives.
AISI 4140 steel is alloyed with chromium and molybdenum, hence the term chromoly steel. The addition of these alloying elements and its relatively high carbon content (around 0.40%) provide this low-alloy steel with excellent strength to weight ratio and make it a lot stronger and harder than standard 1018 and 1020 steels.

C1018 is a general purpose carbon steel that is easily machined and welded and may be hardened by carburizing and by other surface-hardening methods. C1018 is forged from around 2300F down to a temperature in the region of 1650F (1260C down to 900C.).
4130 i did alot of big stuff with 4130 for offshore oil, i dont think, mayby im incorrect but there is much of a difference in 4130-4140, all our stuff was mag,d x rayed and ut tested. its been 30 years or so since i last welded this stuff and we had to follow strict procedures, so we never had to think for ourself, what i do remember it is critical to prehaet to 500 and keep it there through best 1020 steel rc
1215 Fast cutting steel is considered the standard screw stock. Cutting speeds and machining characteristics are excellent. 1215 is a resulphurized and rephosphorized free machining steel, commonly referred to as screw machine stock. 1215 is an improved free machining steel that has replaced the Bessemer B1113 grade years ago. 1215 is especially suited for automatic screw machine operations best 1020 steel rc
CrNiMo-alloyed heat-treatable steel with very high hardenability for highly-stressed parts in general mechanical engineering applications where large cross-sections and very high toughness are the requirements, such as axles, pins, fasteners, shafts and gear components.
4140 alloy steel is a low alloy steel that contains chromium, molybdenum, and manganese. Because it contains chromium and molybdenum it is sometimes referred to as Chromoly Steel. 4140 also has high fatigue strength, excellent strength to weight ratio, abrasion and impact resistance, and torsional strength.

Stormcrow, the steel used and the heat treat are somewhat shape dependent on power hammer dies. 1) 4140 is an OK die steel but is not recommended for radical shaped dies such as narrow fullering, crown and so on. 2) Fully hardened 4140 ranges from 54 to 59 HRC. But it should be tempered for any heavy use.
1045 is a medium tensile low hardenability carbon steel generally supplied in the black hot rolled or occasionally in the normalised condition, with a typical tensile strength range 570 - 700 Mpa and Brinell hardness range 170 - 210 in either condition.Characterised by fairly good strength and impact properties, plus good machinability and reasonable weldability in the hot rolled or normalised best 1020 steel rc
