Product Information
Technical Overview
A sulfur-bearing iron alloy used to raise sulfur in free-machining steels and selected cast-iron routes.
Product Highlights
- Three sulfur levels — FeS30, FeS40 and FeS50 — for different target chemistries
- Deliberate sulfur addition where machinability rather than desulfurisation governs
- Batch traceability with a Manufacturer Test Report issued for every lot

Applications
Used to raise sulfur deliberately in free-machining steels and selected cast-iron routes, where sulfur control is an addition rather than a removal task.
Technical Notes
Grades FeS30, FeS40 and FeS50 cover different sulfur levels. The material should be kept dry and handled to the agreed instructions.
The values above are product-reference data for technical evaluation. Final acceptance criteria follow the signed specification, contract and batch MTR.
