1018 steel is used over a36 for applications that require machining as it responds to machining fairly well.
A36 is favored for structural purposes while 1018 is more suited for machining and finishing purposes.
1018 is most commonly used in high volume screw machine parts including shafts spindels pins and rods.

The difference between 1018 steel and a36 steel is in the finish yield strength and price.
As we know a lot of countries have their own national standards for steel production.
So astm a36 steel plates will have a lot of equivalent materials such as a283c fe360b e24 2 chinese material q235b japan material ss400 and sm400a european material en s235jr germany material din st37 2 etc.
While both 1018 and a36 come in hot rolled or cold rolled forms hot rolled a36 steel and cold rolled 1018 steel are the most common.
A36 mild steel is often compared to aisi 1018 a36 carbon steel is commonly hot rolled while 1018 steel is commonly cold rolled.
Different tensile strength a36 400 550mpa q235b 375 500mpa.
While there are still differences you can get more detail info from here q235b steel equivalent standard astm a36.
