Material specifications
Vlier plunger material grades and descriptions as well as finish plating's are summarized in the tables and notations shown below:
| Material | Description | Component* |
|---|---|---|
| Stainless Steel | Good in corrosive environments food processing and high temperature applications (spring can withstand 600°F) Grades: 440C***, 300 Series per ASTM A-484 or ASTM A-582, 17-PH | B,P,L,S |
| Carbon Steel | Less expensive material than stainless steel and better wear resistance of the plunger tip due to case hardening.** Grades: 11L17 or 12L14A or Ledloy AX | B,P |
| Music Wire | Used on most carbon steel products. | S |
| Nylon or Delrin® | Will not mar soft material such as aluminum or brass. | B,P,L |
| Phenolic | Will not mar soft material such as aluminum or brass. More brittle than nylon or Delrin. | B,P |
* Componant: (B) Body, (P) Plunger, (L) Ball, (S) Spring
** Note: All steel plungers are typically case hardened to 0.15-.010 inches in depth to a hardness of between RC 58-62.
Finish Platings
- Zinc plate; yellow, clear or black chromate to conversion coat
- Black oxide
- Passivate; SAE-AMS-QQ-P-35, ASTM-A-967***
- Other special coatings
