1117

This 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.

1144A

Medium   carbon, usually cold-drawn. Can be heat treated. Welding requires special   practices and residual control.

1215

Free   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.

12L14

A   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.

40

Used for   rebar. Offers a minimum yield strength of 40,000 PSI.

60

Used for   rebar. Offers a minimum yield strength of 60 KSI.

A311-B

Excellent   machinability, resistance to fatigue and stress, strengthened without heat   treating. 

A36

Low   carbon steel that exhibits good strength coupled with formability. It is easy   to machine and fabricate and can be securely welded.

A706

Low   alloy. Easiest grade to weld.

A-2

Air-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-2

High   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-2

General   purpose high speed steel. Most widely used in the M series.

O-1

Oil   Hardening. Easy to machine. Good abrasion resistance. Most widely used in O   series.

S-7

Shock   resistant tool steel. Used in applications that require high toughness and   resistance. Used for moderately elevated temperature service.

4130

General   purpose alloy. Offers good strength and toughness for moderately stressed   parts.

4140

Medium   carbon steel that is widely used for general purposes. Good hardenability,   strength, toughness, wear resistance, and ductility.

4150

Similar   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.

4340

Highly   alloyed steel. Used in heavy-duty conditions and for heavily stressed parts.

52100

A 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.

8620

General   purpose alloy. It is the most widely used of all case hardening alloys.

86L20

Case   hardening steel that is supported by a tough, ductile core. Minimal   distortion in heat treatment.

360

Wide   range of applications. Highest rated among copper alloys. Fair soldering and   brazing capabilities.

464

Referred   to as Naval brass. High strength, corrosion resistant alloy. Excellent   soldering and brazing capabilities.

110

Broad   range of uses. Excellent hot and cold forming characteristics. Poor   machinability rating. 

145

Free   machining copper. High conductivity. Relatively good machinability rating.

932/SAE   660

High   strength, wear and corrosion resistance. Welding, soldering and brazing   are possible but not recommended.

954

Most   popular among bronze alloys. Provides high tensile and yield strength. Good   ductility, weldability, and machinability. Excellent resistance to wear,   fatigue, and deformation.

1100

Commercially   pure aluminum. Soft and ductile, has excellent workability and formability   and high thermal and electrical conductivities. Non-heat treatable.

2011

One of   the most commonly used high strength aluminum alloys. Low corrosion   resistance. Commonly used when good strength-to-weight ratio is desired.

2017

Has 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.

2024

One of   the most commonly used high strength aluminum alloys. Low corrosion   resistance. Commonly used when good strength-to-weight ratio is desired.

6061,   6063, 6262

Heat   treatable, structural alloy with medium strength and good weldability,   formability, machinability, and relatively good corrosion resistance.

7075

Highest   strength in heat treatable alloys. Adequate machinability and improved stress   corrosion control. Good for highly stressed structural parts.

17-4 PH

Precipitation   hardened, can be heat treated to high levels of hardness and strength.   Features machinability and corrosion resistance.

303

Corrosion   resistant to sterilizing solutions, most organic and inorganic chemicals, most   dyes, nitric acid, and atmospheric exposures.

304

Offers   resistance to corrosion, has good formability and can be readily welded by   all methods. One of the most commonly used grades across the industry.

304L

Extra   low carbon avoids harmful carbide precipitation due to welding. Same   corrosion resistance as 304 with lower mechanical properties.

316

Better 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.

316L

Extra   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.

416

Good corrosion   resistance. Additional sulfur in its chemistry makes 416 easier to machine.

440 F-Se

One of   the hardest stainless steels. The extra carbon allows for a long lasting   sharp edge when heat treated properly.
