1117 Stainless Steel

1117 is a high manganese, low-carbon stainless steel possessing high machinability and great mechanical properties. It is alloyed with different elements namely carbon, copper, nickel, chromium, aluminum, and molybdenum. AISI 1117 has more manganese content compared to other low-carbon steels for it to have good hardenability characteristics.

This type of stainless steel is best suited for machined part application in which parts need to be subsequently case carburized. This process is the additional operation to retain ductile core in carburized parts to attain good surface hardness.

1117 is an ideal material to be used in the manufacturing of parts subjected to vibrating stresses and shock. .15/.35% of lead added to the material improves its free-machining characteristics without sacrificing its carburizing properties.

This grade type does exhibit excellent physical and mechanical properties like yield strength, elongation, tensile strength, and Brinell hardness.

AISI 1117 is basically applied in the manufacturing of numerous parts that require close tolerance and considerable machining properties, with a smooth finish. They are best applied in automatic screw machines.

1117 is usually bent or formed in not too severe cold working operations. Some of its designated for carburized parts in which high surface and soft care are needed:

• Pinions
• Ratchets
• Cam shafts
• Medium-duty shafts
• Gears
• King pins
• Worms
• Studs
• Universal joints

1117 stainless steel should be machined at approximately 170 surface ft./ minute. It possesses average cutting speed of 150 ft./minute and machinability rating at 91 percent of B1112. Its high sulfur content makes its hard to weld.

1117 can readily respond to heat treatments and carburizing methods. Hard case and soft core are achieved after case hardening operations.
