Type 303 stainless steel wire is the most readily machinable of all the austenitic grades of stainless steel.
The machinable nature is due to the presence of sulphur in the steels composition.
The sulphur improves machining, though it also causes a decrease in the corrosion resistance and a
slight lowering of the toughness. The corrosion resistance of 303 is lower than that of 304.
Stainless alloy 303 is most commonly used in nuts, bolts, screws, gears, aircraft fittings, and bushings.
Type 17-7 Stainless Steel
17-7PH is a precipitation hardening stainless steel that provides high strength and hardness,
excellent fatigue properties, good corrosion resistance, good formability, and mini- mum distortion
upon heat treatment.
The alloy provides valuable property combinations particularly well suited for aerospace applications.
This special alloy also provides benefits for other applications requiring high strength and good corrosion resistance,
as well as excellent properties for flat springs at temperatures up to 600°F (316°C).
Type 410 stainless steel is a martensitic hardendable high-strength iron/chromium.
Stainless 410 is wear-resistant, but less corrosion-resistant than many other types.
Type 416 stainless steel wire is easily machinable due to additional sulfur.
Type 416 stainless is an electric furnace processed, magnetic, free-machining grade of
the martensitic stainless steels.
It is a modification of Type 410 with approximately .30% sulfur added for excellent machinability.
Like Type 410, it has an exceptionally wide range of mechanical properties obtainable through heat treating,
This grade of stainless steel has the highest machinability of all grades now developed,
and can often be used in the "as machined" condition without heat treatment.
Applications
Because of its excellent machinability, corrosion resistance, and high strength.
Type 416 is normally used for applications requiring extensive or high speed machining such as:
nuts and bolts; pump parts; screw machine parts; and etc.
Corrosion Resistance
This grade has very good overall corrosion resistance to normal atmospheric conditions,
mildly corrosive chemicals, and acidic or alkaline water.
Hardening and polishing increases its corrosion to its maximal level.
Resists scaling at temperatures up to approximately 1300° F.
Type 420 stainless steel wire has fair-to-good corrosion resistance and good material strength.
Stainless 420 resists corrosion from alcohol, ammonia, food environments, fresh water,
many petroleum products and organic materials and some mild acid environments.
They are found in bearings, valves, lighters and writing instruments.
Type 430 stainless steel wire provides fair to-good corrosion resistance.
Type 430 resists corrosion from fresh water, steam, food environments, dairy products,
nitric acid and many petroleum products and organic material.
Applications include balls in cosmetics agitators such as nail polish and eyeliners,
as dispenser pump balls and valve balls.
