1.4057 - ATA GLANCE

What kind of steel is the 1.4057?
The added chromium and nickel alloys, givesvthe 1.4057 (X17CrNi16-2) a better toughness as well as better corrosion resistance compared to straight up chromium stainless steels. This makes this steel grade ideal for operations like deep drawing, compressor parts and construction. This steel grade is also often used in processing chemically aggressive plastics, like PVC for instance.

Properties
As with all material choices, applications and properties should be considered when choosing a steel. The 1.4057 offers good corrosion resistance in mild to moderate corrosive environments but is susceptible to pitting when exposed to chloride rich environments. It has high tensile strength, good machinability and can achieve mechanical properties like hardness or toughness by heat treating this material.
- Martensitic chromium steel
- High strength in as-delivered condition (quenched and tempered)
- Very good corrosion resistance
- High toughness
- High tensile strength
- Good machinability
- Good weldability
- Magnetizable
- Limited acid resistance
- Forgeable

Applications
Due to its tensile strength and corrosion resistance 1.4057 can be used for fasteners like bolts and screws or mechanical components like shafts and axles. Furthermore it can be used for pumps and valve components, aircraft components like landing gear or pivot pins.
Automotive parts like engine components and exhaust system parts or in the food processing industry as it can withstand harsher cleaning processes. With its sharpness and corrosion resistance the 1.4057 lends itself for cutlery and surgical instruments.
