MERCHANT BAR QUALITY
Bars should be free from visible piping. Seams and other surface irregularities may be present. Easily machined, welded, and formed but not particularly recommended for forging, heat treating or complicated machining operations. Conforms to ASTM A575 and QQ-S-630 Standards.
M1010 —This is a Low carbon, general purpose merchant quality steel that offers economy plus formability and weldability.
M1020 — A low carbon, general purpose merchant quality steel, produced to wider carbon and manganese ranges than standard steels that is suitable for forming and welding.
M1044 merchant quality steel is similar to AISI 1045. Because it contains lesser amounts of manganese (.25/.60), strength and responsiveness to heat treatment are slightly lower.
ASTM A36 — Bars designed for use in structural applications. Minimum physical properties of 36,000 psi yield strength and 58,000 psi tensile strength.
1018 — 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 ASTMA-108 standards.
GROUND & POLISHED SHAFTING
Extreme size accuracy, straightness and concentricity to minimize wear in high speed applications. Turned, ground & polished bars can be machined unsymmetrically as in key-seating, with minimum distortion because cold drawing strains are not developed. Drawn, ground & polished bars combine the strength advantages of cold drawn stock with extra accuracy and lustrous finish. Conforms to ASTM A-108 and QQ-S-637 standards.
