The specified properties may not be similar to other forms such as forgings and wires. With most of the free-machining stainless steels, the machinability can be improved by adding sulphur, which leads to the formation of manganese sulphide inclusions.

Addition of sulphur also reduces the formability, weldability and corrosion resistance of stainless steel flat bar to below that of grade stainless steel. Because of their high machinability and low cost, grade stainless steel rod are available in highly tempered, hardened or unhardened forms. Martensitic steels with high hardness are manufactured using methods that require final hardening and tempering treatments. The corrosion resistance of these steels is lower than that of austenitic steels.

Decrease in the ductility of martensitic steels at sub-zero temperatures, and strength at high temperatures due to over-tempering, are the two key factors that affect their operating temperatures. Astm A Properties - These steels are designed especially for optimum machinability, as well as general corrosion and high-temperature service. At least one hardness testing is required midway between surface and center; this determines that the material conforms to hardness requirements.

The high machinability of can be sacrificed to gain better corrosion resistance and formability. A free-machining Ferritic grade with better "soft magnetic" performance for solenoid shafts.

More A It includes rounds, squares, and hexagons in the more commonly used types of stainless free-machining steels designed especially for optimum machinability and for general corrosion and high-temperature service. Stainless steel bars other than the free-machining types are covered in a separate specification Note 2. The values stated in either inch-pound units or SI metric units are to be regarded separately as standard: within the text and tables, the SI units are shown in [brackets].
