SUS 303 Hard Chrome Plated Steel Bar
Description
SUS303 is a stainless steel material frequently used for manufacturing shafts. The following are the key characteristics of SUS303, particularly when subjected to plating treatments:
1. Material Characteristics: SUS303 is a free-machining stainless steel. It contains a higher sulfur content, which provides significantly better machinability compared to SUS304.
2. Corrosion Resistance: The corrosion resistance of SUS303 is slightly lower than that of SUS304, especially in environments with high sulfur content or acidic conditions.
3. Plating Performance: While the surface finish after plating is generally high, the high sulfur content in the base metal may occasionally affect the uniformity and adhesion of certain plating types.
4. Mechanical Properties: Both SUS303 and SUS304 possess good strength and toughness, making them suitable for manufacturing components like shafts that must withstand high stress.
5. Applications: SUS303 is commonly used in applications requiring high machinability, such as bolts, nuts, and precision shafts.
When selecting SUS303 as a material for plated shafts, the decision should be based on the specific operating environment and the complexity of the machining requirements.
