For over 30 years Deloro Stellite has provided high performance products for the glass industry. We continue to innovate products which help glass manufacturers achieve performance levels by extending the life of critical parts and performance, and by reducing contamination.
Manufacturers of glass components require elevated temperatures to ‘work’ the glass. The heat and the abrasive nature of molten glass cause wear on many components. Deloro Stellite products are used on mould edges to prevent such wear and therefore maximise production efficiencies.
Deloro® powders are commonly chosen due to their combination of heat & corrosion resistance coupled with their thermal shock and thermal conductivity properties. Traditionally glass manufacturers have applied our powders by manual welding, however PTA welding is becoming more popular. As you can see from the table below, Deloro Stellite are happy to offer powders for either method of deposition.

General Uses
|
|
Deloro® 21 KX
|
21-28 HRC
|
Manual Welding
|
Good general use powder. Used for building edges or local repair. Hardness depends on base material. Commonly used on Minox.
|
|
Deloro® 22 KX
Deloro® 22 KS
|
20-22 HRC
|
Manual Welding
|
Good general use powder. Can be used for building up edges or local repair. KS is finer and so is better suited to repair. Can be hand finished.
|
|
Deloro® 29 KX
|
27-30 HRC
|
Manual Welding
|
Similar to Deloro® 22 but slightly harder. Machine finish required.
|
|
Deloro® 34 KX
|
33-37 HRC
|
Manual Welding
|
Slightly harder than Deloro® 29. More commonly used for neck rings & guide plates. Well suited to Minox.
|
|
Deloro® 40 KX
Deloro® 40 S
|
38-42 HRC
|
Manual Welding
|
Slightly harder than Deloro® 34. Used on neck rings & baffles. Can also be used for spray & fuse onto plungers.
|
|
Deloro® 22 WM
|
20-22 HRC
|
PTA
|
Tough Build up alloy for Cast Iron & Steel Components. Used extensively for the manufacture & repair of hollow glass moulds.
|
|
Deloro® 25 WM
|
25-28 HRC
|
PTA
|
Similar to Deloro® 22 but slightly harder & more fluid.
|
|
Deloro® 30 WM
|
27-30 HRC
|
PTA
|
Intermediate properties between Deloro® 25 & 35. Used for the hardfacing of Neck Rings & Baffels in glass industry.
|
|
Deloro® 105 E
|
24-26 HRC
|
PTA
|
Specially designed for the deposition onto Minox by PTA welding. Easily machinable.
