Rounds are an extruded product that are very versatile and have a wide range of applications. Rounds are widely used for all types of fabrication projects where lightweight and corrosion resistance is a concern.

Carbon Tool Steel Alloy Brass Copper Bronze Aluminum Stainless


1018Mild (low carbon) steel, strong and ductile, has good weldability properties.
1045Medium carbon steel that can be forged satisfactorily. Most common shafting steel.
1117This is a resulphurized steel with good machinability and surface finish, but not as good as the standard screw stocks. Its case hardening characteristics are superior and it develops an excellent core. It brazes satisfactorily but has no more than fair welding properties. A more ductile steel than others of lower manganese content and it cold forms well. Its machinability is rated at 89% of 1212.
1144AMedium carbon, usually cold-drawn. Can be heat treated. Welding requires special practices and residual control.
1215Free machining steel, commonly referred to as screw machine stock, especially suited for automatic screw machine operations where the major requirement is exceptional free-machining quality with a smooth, bright finish. Poor weldability.
12L14A standard resulfurized and rephosphorized grade carbon steel and a free machining steel. The added lead to the chemical composition provides improved machinability but the added lead content also reduces the overall strength of this alloy.
40Used for rebar. Offers a minimum yield strength of 40,000 PSI.
60Used for rebar. Offers a minimum yield strength of 60 KSI.
A311-BExcellent machinability, resistance to fatigue and stress, strengthened without heat treating.
A36Low carbon steel that exhibits good strength coupled with formability. It is easy to machine and fabricate and can be securely welded.
A706Low alloy. Easiest grade to weld.

Tool Steel

A-2Air-hardening steel. Replaces O-1 when safer hardening, better dimensional stability and increased wear-resistance are required. Most widely used in the A series.
D-2High carbon and high chrome. Ideal grade for maximum production runs. Superior machinability. Excellent wear-resistance, high compressive strength, and deep hardening properties. Most widely used in the D series.
M-2General purpose high speed steel. Most widely used in the M series.
O-1Oil Hardening. Easy to machine. Good abrasion resistance. Most widely used in O series.
S-7Shock resistant tool steel. Used in applications that require high toughness and resistance. Used for moderately elevated temperature service.


4130General purpose alloy. Offers good strength and toughness for moderately stressed parts.
4140Medium carbon steel that is widely used for general purposes. Good hardenability, strength, toughness, wear resistance, and ductility.
4150Similar to 4140, but increased carbon content leads to higher hardenability. Offers excellent machinability and tool life.
41L40,Can be quenched and tempered for a broad range of strength levels.
4340Highly alloyed steel. Used in heavy-duty conditions and for heavily stressed parts.
52100A high carbon, chromium containing, low alloy steel. A moderately deep hardening alloy with high resistance to wear, medium toughness and low resistance to softening at high temperatures.
8620General purpose alloy. It is the most widely used of all case hardening alloys.
86L20Case hardening steel that is supported by a tough, ductile core. Minimal distortion in heat treatment.


360Wide range of applications. Highest rated among copper alloys. Fair soldering and brazing capabilities.
464Referred to as Naval brass. High strength, corrosion resistant alloy. Excellent soldering and brazing capabilities.


110Broad range of uses. Excellent hot and cold forming characteristics. Poor machinability rating.
145Free machining copper. High conductivity. Relatively good machinability rating.


932/SAE 660High strength, wear and corrosion resistance. Welding, soldering and brazing are possible but not recommended.
954Most popular among bronze alloys. Provides high tensile and yield strength. Good ductility, weldability, and machinability. Excellent resistance to wear, fatigue, and deformation.


1100Commercially pure aluminum. Soft and ductile, has excellent workability and formability and high thermal and electrical conductivities. Non-heat treatable.
2011One of the most commonly used high strength aluminum alloys. Low corrosion resistance. Commonly used when good strength-to-weight ratio is desired.
2017Has high strength with excellent fatigue strength. Alloy 2017 also has very good machining characteristics. It is suitable for welding only by resistance welding. Alloy 2017 is used for various applications from high strength structural components, aircraft, machine construction, military equipment, and rivets.
2024One of the most commonly used high strength aluminum alloys. Low corrosion resistance. Commonly used when good strength-to-weight ratio is desired.
6061, 6063, 6262Heat treatable, structural alloy with medium strength and good weldability, formability, machinability, and relatively good corrosion resistance.
7075Highest strength in heat treatable alloys. Adequate machinability and improved stress corrosion control. Good for highly stressed structural parts.


17-4 PHPrecipitation hardened, can be heat treated to high levels of hardness and strength. Features machinability and corrosion resistance.
303Corrosion resistant to sterilizing solutions, most organic and inorganic chemicals, most dyes, nitric acid, and atmospheric exposures.
304Offers resistance to corrosion, has good formability and can be readily welded by all methods. One of the most commonly used grades across the industry.
304LExtra low carbon avoids harmful carbide precipitation due to welding. Same corrosion resistance as 304 with lower mechanical properties.
316Better pitting and corrosion resistance than 304, as well as higher strength at elevated temperatures. 316 can be used for valves, marine equipment, pumps, and chemical equipment.
316LExtra low carbon avoids harmful carbide precipitation due to welding. Same excellent corrosion resistance as 316. It exhibits the same high strength, toughness and workability as 304 alloys.
416Good corrosion resistance. Additional sulfur in its chemistry makes 416 easier to machine.
440 F-SeOne of the hardest stainless steels. The extra carbon allows for a long lasting sharp edge when heat treated properly.
