Superplast® Stainless
Superplast Stainless is a prehardened, free-machining, stainless mold steel specially designed for plastic mold bases.
Available in plate up to 5.9 inches.
OVERVIEW
Superplast Stainless is a prehardened, free-machining, stainless mold steel specially designed for plastic mold bases. It also provides improved performances compared to standard grades such as W1.2085.
Applications include:
Plastic Molds
Zinc Diecasting Dies
Short Run Aluminum Diecasting Dies
Plunger Tips & Sprue Bushings
Die Plate Strippers
Dies for Aluminum Extrusions
Patterns & Core Boxes
Others
UNIQUE CHARACTERISTICS
Superplast Stainless offers Plastic & Rubber molds:
- Improved machinability
- Improved consistency and weldability
Moreover, thanks to its low Carbon and 12% Chromium content, Superplast Stainless ensures good corrosion resistance, both in humid atmospheres and in corrosive molding environments (PVC).
PRODUCT BROCHURE
CHEMICAL COMPOSITION
With its low Carbon and 12% Chromium content, Superplast Stainless offers excellent corrosion resistance in molding, harsh environments and high humidity conditions.
CORROSION RESISTANCE
Thanks to its specific chemistry with a low carbon content, high level of chromium, and other appropriate alloying elements, Superplast Stainless offers good corrosion resistance in corrosive molding environments (PVC) and in humid atmospheres.
Humid-dry alternated atmosphere test.
MACHINABILITY
Stainless. Performances are definitively improved compared to conventional grades.
Machining test parameters
MECHANICAL PROPERTIES
* HRC Hardness is only indicative value (translation from HB according to ISO 18265 : 2003 table B2)
MICROSTRUCTURE
Superplast Stainless is a martensitic stainless steel offering microstructure and hardness consistency through thickness.
Example in a 100 mm (4”) thick plate.
WELDING GUIDELINES
The low carbon content offers a good aptitude for weld repairs, avoiding any risk of cold cracking when appropriate welding wire is used.
