Introduction
Ferro silicon 72 and ferro vanadium 80 are essential ferroalloys in steelmaking, but they serve distinct industrial functions based on their chemical compositions. As a leading Chinese manufacturer and supplier, ZhenAn International Co., Limited (ZhenAn) provides both alloys with factory-direct pricing and customized solutions.
Chemical Composition Differences
Ferro silicon 72 is an iron-silicon alloy with a silicon content of 72% minimum, balanced by iron and trace impurities. Its typical composition includes ≤2% aluminum, ≤1% calcium, ≤0.04% phosphorus, ≤0.02% sulfur, and ≤0.2% carbon .
Ferro vanadium 80, by contrast, is an iron-vanadium alloy containing 78-82% vanadium. Its impurity profile includes ≤1.5-2.0% aluminum, ≤0.05-0.06% phosphorus, ≤1.50% silicon, and ≤0.15-0.20% carbon .
Application
Ferro silicon 72 is primarily used as a deoxidizer in steelmaking, removing oxygen from molten metal to prevent porosity and inclusions . It acts as an inoculant and spheroidizing agent in cast iron production, promoting graphite formation in nodular cast iron . Additionally, it serves as a reducing agent in ferroalloy manufacturing and magnesium smelting .
Ferro vanadium 80 functions as an alloying agent to enhance steel properties. Adding it increases tensile strength, hardness, wear resistance, and ductility in alloy steels . It is widely used in high-strength structural steel, tool steel, and stainless steel electrode coatings, with 85% of global ferro vanadium consumption directed to the steel industry .

FAQ
Q1: Can ferro silicon 72 substitute ferro vanadium 80 in steelmaking?
A1: No. Ferro silicon 72 primarily acts as a deoxidizer, while ferro vanadium 80 enhances mechanical properties. They serve distinct functions and cannot be substituted.
Q2: What is the lead time for custom ferro silicon 72 orders?
A2: As a factory with large inventories, standard orders ship immediately. Custom productions are fulfilled within agreed timelines based on specifications.
Q3: How does ZhenAn guarantee product quality?
A3: We conduct four rounds of testing, including raw material checks, molten metal analysis, physical property verification, and pre-shipment inspections .
Q4: What packaging options are available?
A4: Standard packaging includes 10kg/25kg waterproof bags in 1MT bulk bags. Custom packaging is available upon request.
