Frequently Asked Questions
Q: What are the main applications of Carbon Steel (1215) inserts?
Carbon Steel (1215) features surface zinc plating and is highly recommended for low-strength host materials such as aluminum alloys, copper alloys, and plastics to provide durable thread reinforcement.
Q: When should I choose Stainless Steel (SUS303, 304, 316) over Carbon Steel?
Stainless steel options should be selected when the application environment requires high corrosion resistance or high-temperature tolerance, such as in marine applications, medical devices, and food processing equipment.
Q: What is the benefit of the zinc plating on the Carbon Steel 1215?
The surface color zinc plating acts as a protective layer, enhancing the wear resistance of the carbon steel and offering basic rust protection in dry or indoor environments.
Q: Which stainless steel grade is best for harsh marine environments?
For marine and highly corrosive environments, SUS316 offers the highest level of corrosion and pitting resistance compared to SUS303 and SUS304 due to its molybdenum content.
Q: Are these inserts compatible with plastic materials?
Yes, the Carbon Steel (1215) inserts are specifically designed to work seamlessly with plastics, providing strong, wear-resistant threads without damaging the base material.
