Selection Considerations & Custom Development
Sealing Glass for Steel can be developed for a range of steel materials,including carbon steel such as SPCC cold-rolled carbon steel,and stainless steels such as 304 and 316. The appropriate sealing glass should be selected based on the steel grade,coefficient of thermal expansion,sealing temperature and seal design.
Key factors include the coefficient of thermal expansion of the steel,sealing temperature,component geometry,and hermeticity requirements.Sinopride can provide material selection support based on specific sealing conditions and component designs.
Ready-to-press glass granulates are suitable for customers with in-house pressing and binder burnout processes. Glass preforms are supplied in defined shapes and dimensions for specific sealing structures,reducing additional forming steps before sealing.
Yes.glass composition and color can be developed according to specific application requirements. Glass preforms can also be customized in shape,dimensions,and color to match different component designs.
The main difference is the metal system they are designed to seal with. Steel sealing glass is developed for steel materials such as carbon steel and stainless steel,while Kovar sealing glass is designed for Kovar alloys. Their glass compositions and thermal expansion characteristics are therefore selected for different metal sealing systems.
