Carbon

GradeDescription
1018Mild (low carbon) steel, strong and ductile, has good weldability properties.
1055Right on the border between a medium and a high carbon steel.
A36Low carbon steel that exhibits good strength coupled with formability. It is easy to machine and fabricate and can be securely welded.
M1044Medium carbon steel used in general purpose applications when special quality is not required. It has good overall properties somewhat higher than low-carbon mild steel.

Stainless

GradeDescription
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.
304Among the most commonly used grades across the industry, it offers resistance to corrosion. Has good formability and can be readily welded by all methods.
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. Free machining variation of T410 with corrosion resistance to most atmospheres, basic salts, water, and natural food acids.

Aluminum

GradeDescription
2024One of the most commonly used high strength aluminum alloys. Low corrosion resistance. Commonly used when good strength-to-weight ratio is desired.
6042Heat treatable, structural alloy with medium strength and good weldability, formability, machinability, and relatively good corrosion resistance.
6061Heat treatable, structural alloy with medium strength and good weldability, formability, machinability, and relatively good corrosion resistance.
6063Heat treatable, structural alloy with medium strength and good weldability, formability, machinability, and relatively good corrosion resistance.
6082Heat treatable, structural alloy with medium strength and good weldability, formability, machinability, and relatively good corrosion resistance.
6101Heat 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.

Alloy

GradeDescription
4140Medium carbon steel that is widely used for general purposes. Good hardenability, strength, toughness, wear resistance, and ductility.

Brass

GradeDescription
360Wide range of applications. Highest rated among copper alloys. Fair soldering and brazing capabilities.

Copper

GradeDescription
110Broad range of uses. Excellent hot and cold forming characteristics. Poor machinability rating.

Bronze

GradeDescription
954Most popular among bronze alloys. Provides high tensile and yield strength. Good ductility, weldability, and machinability. Excellent resistance to wear, fatigue, and deformation.

Tool Steel

GradeDescription
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. 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.
