Merchant Bar Quality

Only a minimum discard is made from each ingot, but bars should be free from visible piping. Seams and other surface irregularities may be present. Chemistry is subject to ladle analysis only. Easily machined, welded, and formed but not particularly recommended for forging, heat treating or complicated machining operations.
ASTM A36 - Bars designed for use in structural applications. Minimum physical properties of 36000 psi yield strength and 58000 psi tensile strength.
Conforms to A-36. Standard length 20'

Is the most widely used steel for screw machine parts applications. Improved machinability is obtained by the addition of lead which acts as an internal lubricant allowing increased machining speeds and prolonging cutting tool life. Conforms to ASTM A-108.

A low carbon steel with a medium manganese content. Has good hardening properties, fair machinability and is excellent for cold bending and forming operations Readily brazed and welded. Suitable for shafting and for applications that do not require the greater strength of high carbon and alloy steels. Conforms to ASTM A-108 and AMS 5069. (Not applicable to bars under 2 15/16" and sizes lighter than 29.34 lbs per foot.)

Is a higher carbon content imparts increased strength to the steel. Response to heat treatment is excellent and the resulting mechanical properties which can be obtained permit a wide usage in the production of machinery parts and shafts. Conforms to ASTM A- 108.

Is a medium carbon, resulphurized, free cutting steel that responds well to heat treatment. The relatively high carbon, high manganese content provides a steel with good strength and wear resistance. It is often used for induction hardened parts, and screw machine applications. Conforms to ASTM A-108.

Is the most widely used steel for screw machine parts applications. Improved machinability is obtained by the addition of lead which acts as an internal lubricant allowing increased machining speeds and prolonging cutting tool life. Conforms to ASTM A-108.

Conforms to A615-40, A615-60 and A706-60.
The bar numbers are based on the number of 1/8 inches included in the nominal diameter of the bar.
