Product Detail
Product Introduction
Titanium spring pins are interference-fit hollow pins used for location, light retention or shear transfer where corrosion compatibility and low mass are important. Titanium elastic modulus, strength, springback and wear differ from common spring steels, so the pin section, free diameter, hole limits, insertion force and service load must be validated as a system.
Product Specifications
| Product | Titanium Spring Pins | Grade | Titanium grade and condition by approved design |
|---|---|---|---|
| Standard | ISO 8752 and DIN 1481 may be used as dimensional starting points for slotted spring-pin forms when expressly invoked. Their standard steel material and spring-performance assumptions do not transfer automatically to titanium. The approved drawing must define titanium grade and condition, pin section, hole limits and functional acceptance. | Size & Form | Nominal and free diameter, length, wall or section, longitudinal slot, chamfer and mating-hole limits |
| Tolerance | Drawing-defined free geometry, straightness, slot, hole fit and functional insertion/retention acceptance | Supply Condition | Formed and condition-controlled as approved; deburred, cleaned, function checked and lot identified |
| Inspection | Available controls include MTC review, nominal and free diameter, wall or section, slot, length, chamfer, straightness, sample hole fit, insertion or retention force, shear test where agreed and lot traceability. | Documents | MTC, heat/lot traceability and agreed inspection reports |

FAQ
Can a titanium spring pin directly replace a steel roll pin?
Not without engineering validation. Titanium stiffness, springback, strength and wear differ, so pin geometry, hole tolerance, insertion force and load capacity must be reviewed.
Which hole information is required?
Provide hole diameter and tolerance, material, wall thickness, finish, edge preparation and whether installation is manual or automated.
What functional tests can be specified?
Depending on the joint, sample insertion and retention force, shear, cyclic loading, corrosion exposure and post-installation dimensional checks may be agreed.
