General Information: Spheric Trafalgar's stainless steel balls made from AISI 440C offer maximum hardness and good corrosion resistance in environments such as fresh water, steam, crude oil, gasoline, alcohol, food, blood, and perspiration. The material is ferro-magnetic and can serve as a fair permanent magnet. Post heat treatment, the balls are deep freeze stabilized.

International Equivalents: The material corresponds to several international standards: AISI 440C, DINX105 CR Mo17, JIS SUS 440C, Z100CD17, and Wks 1.4125.

Material Specification: The composition includes Carbon (0.95 - 1.20%), Chromium (16 - 18%), Silicon (max 1.0%), Manganese (max 1.0%), Phosphorus (max 0.04%), Sulfur (max 0.03%), and Molybdenum (max 0.75%).

Hardness: The hardness of the material is rated between HRc 57 - 60.

Mechanical Properties: The tensile strength is 285,000 psi, yield strength is 275,000 psi, and density is 0.277 lbs/cu in.

Size Range: The balls are available in sizes ranging from 0.635mm (0.025") to 101.6mm (4").

Standard Grades Available: The standard grades available are 10, 25, 50, and 1000.
