What does ASTM A108 mean?
What does ASTM A108 mean?
The ASTM A108 (A108M is the equivalent metric version of A108) is a standard specification created to help define the technical requirements for Steel Bars, Carbon and Alloy, Cold-Finished. Steel grades for A108 are defined by their chemical composition.
What is the RC of 1018 steel?
AISI 1018 carbon steel can be case hardened to Rc 42, but only in thin sections. In case of thicker sections of over 4 in., Rc 28-30 can be obtained.
What does AISI 1018 mean?
AISI 1018 is a Standard grade Carbon Steel. It is composed of (in weight percentage) 0.15-0.20% Carbon (C), 0.60-0.90% Manganese (Mn), 0.04%(max) Phosphorus (P), 0.05%(max) Sulfur (S), and the base metal Iron (Fe). Other designations of AISI 1018 carbon steel include UNS G10180 and AISI 1018.
What is the difference between 1018 and A36?
A36 Mild Steel Note that its yield strength is also significantly less than 1018 – this means that it will bend much more quickly than will 1018. Finally, machining this material is noticeably more difficult than 1018 steel, but the cost is usually significantly lower.
What is A311 steel?
A311 Stressproof® Bar is a medium carbon free machining steel. The bar is then stress relieved in a precisely controlled furnace. The result is a steel bar product that meets stringent standards that provide a wide variety of benefits, including: Improved wearability without case hardening.
What type of steel is 1018?
low-carbon steel
1018 cold finished steel is a general-purpose, low-carbon steel with good case hardening qualities. It is especially suited to cold forming and bending operations. 1018 is suitable for parts that require cold forming (such as crimping, swaging, or bending).
What is 1018 steel made of?
Chemical Composition
| Element | Content |
|---|---|
| Carbon, C | 0.14 – 0.20 % |
| Iron, Fe | 98.81 – 99.26 % (as remainder) |
| Manganese, Mn | 0.60 – 0.90 % |
| Phosphorous, P | ≤ 0.040 % |
What is the HRC of 1018 steel?
| Physical Properties | Metric | English |
|---|---|---|
| Hardness, Rockwell B | 92 | 92 |
| Hardness, Rockwell C | 13 | 13 |
| Hardness, Vickers | 207 | 207 |
| Tensile Strength, Ultimate | 634 MPa | 92000 psi |
Is A311 the same as 1144?
Cold drawn 1144 steel bar to ASTM A311 (B) is a process by which 1144 is drafted twice as much as a typical cold drawn bar. The process achieves strength that is comparable to quenching and tempering, while achieving the performance of a free machining steel.

What is ASTM A108?
ASTM A108 covers cold-finished carbon and alloy steel bars produced in straight length and coil to chemical compositions. The steel can then be heat-treated to be used for machining into components or just to be used on an as-is basis.
What is ASTM a 108?
ASTM A 108 is a “Standard Specification for Steel Bars, Carbon, Cold-Finished, Standard Quality”. This Standard provides a UNS designation and Grade designation for the various carbon steel alloys that can cross reference to an AISI designation.
What is 1018 steel used for?
1018 steel is used over A36 for applications that require machining, as it responds to machining fairly well. 1018 is most commonly used in high volume screw machine parts including shafts, spindels, pins and rods.
