On December 5, 2023, internationality Customers Ordered 232 Tons Of Ferrotungsten

Leading ferroalloy supplier ZhenAn International Co., Limited has secured a substantial order for 232 tons of premium ferrotungsten, reflecting sustained global demand for high-grade tungsten iron alloys in advanced steelmaking applications.

Order Details

On December 5, 2023, international customers placed an order for 232 tons of ferrotungsten with ZhenAn International Co., Limited. This significant volume underscores the continued confidence that steel producers and alloy buyers place in ZhenAn's manufacturing capabilities and product consistency. The order was finalized following a direct visit by the customers to ZhenAn's facilities, where they reviewed production processes, quality control protocols, and inventory readiness.

Ferrotungsten is an iron alloy whose primary constituents are tungsten and iron. The material also contains controlled traces of manganese, silicon, carbon, phosphorus, sulfur, copper, tin, and other elements within specified limits. As an essential alloying agent in steelmaking, ferrotungsten imparts critical properties to finished steel products, including elevated hardness, improved wear resistance, and enhanced performance under high-temperature conditions.

Product Specifications and Grades

ZhenAn supplies ferrotungsten in two principal grades tailored to different steelmaking requirements. Each grade is manufactured under rigorous process controls to ensure uniform composition and reliable performance across every batch.

FeW75 contains tungsten in the range of 70% to 80%, with maximum allowable impurities as follows: carbon not exceeding 0.20%, phosphorus not exceeding 0.04%, sulfur not exceeding 0.08%, silicon not exceeding 0.5%, and manganese not exceeding 0.25%.

FeW80 contains tungsten in the range of 75.0% to 85.0%, with maximum allowable impurities as follows: carbon not exceeding 0.20%, phosphorus not exceeding 0.04%, sulfur not exceeding 0.08%, silicon not exceeding 0.7%, and manganese not exceeding 0.25%.

Both grades are produced using established metallurgical methods that preserve the desired tungsten recovery while minimizing undesirable tramp elements. Customers may specify the preferred grade at the time of order based on their end-use specifications and furnace practices.

Applications in Modern Steelmaking

Ferrotungsten serves as a strategic alloying addition in numerous steel grades where tungsten content is required. In tool steels, tungsten contributes to red hardness, enabling cutting tools to retain their edge at elevated operating temperatures. In high-speed steels, ferrotungsten is a fundamental component that supports the formation of hard, stable carbides during heat treatment.

Beyond tool and die applications, ferrotungsten finds use in heat-resistant steels, permanent magnet alloys, and certain specialty grades where a combination of strength and thermal stability is essential. Foundries and electric arc furnace operators value ferrotungsten for its predictable dissolution behavior and consistent yield when added to the melt.

Product Delivery and Packaging

ZhenAn International manages every stage of order fulfillment, from production scheduling through final dispatch. Ferrotungsten is delivered in solid blocks to facilitate handling and furnace charging. Standard block size ranges from 10 mm to 130 mm, with pieces measuring less than 10 mm by 10 mm restricted to no more than 5% of the total batch weight. Individual blocks may reach a maximum dimension of 150 mm in one direction.

The surface of each tungsten iron block is inspected to ensure it remains smooth and clean. Cross-sections and external surfaces must be free from obvious non-metallic inclusions and rust spots. This surface quality standard supports reliable dissolution in the melt and reduces the risk of introducing unwanted contaminants into the customer's steel production process.

Packaging and loading arrangements are coordinated to meet the destination requirements and the customer's preferred logistics schedule. Documentation accompanying each shipment includes certificate of analysis, packing list, and commercial invoice as applicable.

Frequently Asked Questions

Q: What is the difference between FeW75 and FeW80?
A: FeW75 contains 70% to 80% tungsten, while FeW80 contains 75.0% to 85.0% tungsten. The choice between grades depends on the target tungsten addition in your steel recipe and the allowable impurity limits for your finished product. Both grades share the same maximum carbon, phosphorus, and sulfur limits.

Q: How is ferrotungsten used in the steelmaking process?
A: Ferrotungsten is added to the liquid steel bath as an alloying agent, typically during the refining stage in an electric arc furnace or ladle metallurgy station. It dissolves to introduce tungsten into the steel matrix, improving hardness, wear resistance, and high-temperature strength.

Q: What quality certificates are provided with each shipment?
A: Each batch of ferrotungsten is accompanied by a certificate of analysis that documents the actual chemical composition, including tungsten content and all controlled impurity elements. Additional documentation such as packing lists and commercial invoices is provided according to standard export practice.
