What kind of steel is 1215?
carbon steel
Cold drawn 1215 steel bar is resulfurized and rephosphorized carbon steel. This grade is considered free machining, having excellent machinability due to its added sulfur, phosphorus. This grade, also referred to as “screw stock”, is heavily utilized for automatic screw machine operations.
What is the hardness of AISI 1040?

What is the difference between 12L14 and 1215?
Steel 1215 Machined Parts Steel alloy 1215 is a popular free-machining alloy (FMA), ideal for parts that require considerable machining and a bright finish. 1215 has a machining cost factor of 1.2 when compared to steel 12L14. It possesses better weldability and formability than 12L14. 1215 can be heat treated.
What is the maximum hardness of carbon steel?
approximately 65 HRC
In the hardening process, the maximum hardness level (up to approximately 65 HRC) is reached according to the carbon content; during the subse- quent tempering process the hardness is reduced to achieve an optimum combination of hardness and toughness.
Can you harden 1215 steel?
1215 steel is the lead-free replacement for 12L14 leaded steel, with virtually identical properties. This low-carbon, case-hardening steel is an ideal material for many round and hex-shaped parts. This steel has superior case hardening qualities.
What is the Rockwell hardness of 1215 steel?
Mechanical Properties
| Properties | Metric | Imperial |
|---|---|---|
| Hardness, Knoop (converted from Brinell hardness) | 188 | 188 |
| Hardness, Rockwell B (converted from Brinell hardness) | 85 | 85 |
| Hardness, Vickers (converted from Brinell hardness) | 175 | 175 |
| Machinability (Based on 100 machinability for AISI 1212 steel.) | 140 | 140 |
What does AISI 1040 mean?
AISI 1040 is a medium strength steel with good tensile strength. Suitable for shafts, stressed pins, studs, keys etc. We can supply AISI 1040 as round drawn/turned, round hot rolled, hexagon, square, flats and plate.
What is the difference between AISI 1040 and AISI 4140?
AISI 1040 is medium carbon steel used for constructional related structural applications where the property alterations are inevitable [1], [2]. AISI 4140 steel is alloyed steel containing Cr, Mo, Si, and Mn as prominent alloying elements. This steel has higher hardenability, strength, and wear resistance.
Can you weld 1215 steel?
Any type of arc welding of resulfurized steels is generally avoided. This includes steel grades in the 11XX and 12XX series, such as 1215, 12L14, 1117, 1137, and 1144. These steels contain sulfur and may contain lead. These two elements will create low melting temperature constituents that will cause cracks.
What hardness is mild steel?
130
Typical Brinell Hardness Numbers for Metals
| Material | Brinell Hardness Number |
|---|---|
| Mild steel | 130 |
| Annealed chissel steel | 235 |
| White cast iron | 415 |
| Nitrided surface | 750 |
Can you weld 1215?
What is the machinability of AISI 1215 carbon steel?
Machinability (Based on 100 machinability for AISI 1212 steel.) The thermal properties of AISI 1215 carbon steel are outlined in the following table. Other designations that are equivalent to AISI 1215 carbon steel include:
Is 1215 steel case hardening steel?
Although this analysis will respond to conventional treatments, 1215 is not considered to be a case hardening steel. Better results are obtained from 1117 or 1018. Chemical Composition Carbon (C) Max Manganese (Mn)
What are the characteristics of AISI 1212 steel?
This steel series are both rephosphorized and resulfurized. Density, Typical for steel. Bulk Modulus, Typical for steel. Machinability, Based on 100% machinability for AISI 1212 steel. Shear Modulus, Typical for steel.
What is the cutting speed of 1215 steel?
Average cutting speed 225 ft/min. Because of 1215™s very high sulphur content, weldability is considered poor. Although this analysis will respond to conventional treatments, 1215 is not considered to be a case hardening steel. Better results are obtained from 1117 or 1018.
