Unique Heat Number

All Waterson products are engraved with a specific heat number to certify their investment casting material composition.  The 8-digit number represents the pour date and batch associated with each respective item.  This number represents a specific material composition, which meets international standards.  Each item produced by Watetrson is traceable by its unique heat number, which is particularly important for the pharmaceutical, medical, and chemical industries.

Why Material Purity in Casting Matters?

High Impurity Content: The purity of stainless steel significantly impacts its weldability. High levels of impurities such as carbon, sulfur, and phosphorus in the steel can lead to problems like cracks and pores during welding, reducing the strength and corrosion resistance of the weld joints.
