Product catalog summary

Alloy Steel Quik Guide Summary

Nomenclature:

HR (Hot Roll): Original as rolled surface from steel mill, meeting ASTM A29 tolerances.
FGD (Hot Forged): Used for sizes over 10" where HR capabilities diminish.
CF (Cold Finish): Includes rough turned, cold drawn, turned & polished, meeting ASTM A108 tolerances.
RT (Rough Turn): Typically for HR sizes over 6" that can't be CD or T&P.
CD (Cold Drawn): HR drawn through a die, work hardens softer low carbon steels for improved machinability.
T&P (Turned & Polished): CNC high-speed precision turned & polished, considered seam & decarb free.
TGP (Turned, Ground & Polished): Turned & polished then centerless ground to final size.
ANN (Anneal): Softening HR by heating and furnace cooling to provide machinability.
N (Normalize): Heating to ~1650/1700F and air cooling to refine grain and homogenize microstructure.
T (Temper): Heating below critical temperatures to soften normalized or quench hardened material.
Q&T (Quench & Temper): Heating above critical temperatures, quenching in a liquid media, and tempering to desired hardness.

Quality Grades:

CQ: Commercial Quality
AQ: Aircraft Quality
BQ: Bearing Quality
EF: Electric Furnace Quality

Specifications and Properties:

Various grades and sizes are available, each with specific mechanical properties such as tensile strength, yield strength, elongation, and hardness.
Alloys are categorized into low, medium, and high carbon alloys, each with specific applications and properties.
Case hardening steels offer improved machinability and wear resistance.
Thru hardening steels are suitable for induction hardening and offer high strength and toughness.

Applications and Recommendations:

Alloys are suitable for critical applications requiring high wear resistance and toughness.
Specific treatments like annealing, normalizing, and quenching & tempering are recommended based on the desired mechanical properties.
For demanding applications, seam and decarb free alloys are preferred.
