According to the ASME, SAE1010 {ASTM A179, ASME SA179} cold rolled steel (cold drawn) should have a Rockwell hardness of 60 RB. Hot rolled it is reduced to 55 RB.

12L14 steel and SAE 1010 steel are not equivalent, though they are both low-carbon steels. 12L14 is a leaded steel known for its excellent machinability due to the addition of lead, while SAE 1010 is a plain carbon steel with a lower carbon content, offering good weldability and formability. The presence of lead in 12L14 makes it unsuitable for certain applications where lead contamination is a concern. Therefore, while they may share some characteristics, their properties and applications differ significantly.

The hardness of 1010-1020 steel typically ranges from about 55 to 65 Rockwell B (HRB), depending on the specific composition and heat treatment process. These steels are low-carbon grades, which means they are relatively soft and ductile compared to higher carbon steels. They are often used in applications requiring good formability and weldability rather than high hardness. Heat treatment processes can increase hardness but are generally not common for these low-carbon grades.

Therefore, while they may share some characteristics, their properties and applications differ significantly.
The surface finish of SAE 1010 material at 65 HRB typically depends on the manufacturing process used, such as cold rolling or machining. Generally, cold-rolled SAE 1010 can achieve a smoother surface finish compared to hot-rolled versions, often resulting in a finish that ranges from 63 to 125 microinches (1.6 to 3.2 micrometers) Ra. However, the final surface finish can be further improved through additional processes like polishing or grinding, depending on the application's requirements.
SWCH10R is a type of low carbon steel commonly used for making screws. It has good mechanical properties, including high tensile strength and hardness. It is suitable for fastening applications where strength and resistance to deformation are important.

Loader on Massey 1010 tractorThere is a site http://www.loaderplans.com that offers plans for loaders to fit small tractors of all types. The Massey 1010 is similar to Allis and Deutz-Allis models made by Hinomoto, for which the manufacturer and loader manufacturers make models to fit. It should be noted that hydrostatic transmissions are better able to withstand the strain of heavy use such as loader work than gear transmissions. On any tractor the side rails (frame) should be reinforced with plate steel and the side brackets should be fastened to a cross beam under the tractor to prevent stress damage from the loader.
