Partial Substitution

Review Required

Clean Phosphorus Addition For Specialty Steel

Replaced Material
Standard ferrophosphorus with wider impurity ranges
Substitute Material
Low-titanium low-carbon ferrophosphorus
Applicable Steels
Wear-resistant, machinable and specialty alloy steels

Cost Saving

Quality-cost avoidance; project-specific

Cost Logic

<p>Avoid downstream process and quality costs caused by unsuitable titanium or carbon pickup while retaining economical phosphorus addition.</p>

Quality Guarantee

<p>Final impurity limits are confirmed by technical review, trial sample and MTR before mass production.</p>

Partial Substitution

Review Required

Controlled Nitrogen Alloying With Nitrided Ferrochrome

Replaced Material
Separate chromium and nitrogen additions
Substitute Material
High-nitrogen / Nitrided Ferrochrome
Applicable Steels
High-nitrogen stainless, duplex and corrosion-resistant steels

Cost Saving

Operational and material savings depend on recovery and process design

Cost Logic

<p>A combined chromium-nitrogen input can simplify charge design and improve consistency when recovery behavior is validated.</p>

Quality Guarantee

<p>Nitrogen target, carbon limit and particle size are confirmed before trial; each batch is supplied with an MTR.</p>

Partial Substitution

Review Required

Pure Ferrochrome For Partial Chromium Metal Substitution

Replaced Material
Chromium Metal (partial or process-dependent substitution)
Substitute Material
Pure Ferrochrome CJCr01 / CJCr02
Applicable Steels
Precision alloys and high-cleanliness specialty steels

Cost Saving

Illustrative industry example: up to USD 216 per tonne of steel; verify per project

Cost Logic

<p>Use a clean ferrochrome grade with controlled impurities to supply chromium at a lower input cost than chromium metal where the metallurgical route permits.</p>

Quality Guarantee

<p>Substitution ratio is determined by chemistry, recovery and product requirements. No complete-substitution claim is made without validation.</p>

Partial Substitution

Review Required

Nitrided Manganese For Partial Nickel Input Substitution

Replaced Material
Ferronickel / Electrolytic Nickel (partial input)
Substitute Material
Nitrided Manganese
Applicable Steels
Chromium-nickel-manganese stainless steels

Cost Saving

Project-specific; calculated after charge-mix and recovery review

Cost Logic

<p>Introduce manganese and nitrogen through a tailored alloy input, reducing a portion of higher-cost nickel-bearing additions while maintaining the agreed melt and finished-steel requirements.</p>

Quality Guarantee

<p>Partial substitution only. Final adoption depends on trials, chemical analysis and confirmation that steel quality is not compromised.</p>

Application Boundary

Partial Substitution Limitations

A substitute is not a universal one-to-one replacement. The acceptable proportion depends on the target steel grade, melt practice, impurity limits, recovery rate, and final performance requirements.

Published solutions are technical starting points rather than final specifications, production guarantees, or quotations. Plant review and controlled validation are required before volume use.

Verification Control

Quality Commitment

We coordinate technical feasibility checks, trial production where required, and batch-level chemistry documentation through qualified partner plants.

  • COA Or MTR Availability By Confirmed Batch
  • Independent Inspection Coordination When Required
  • Written Chemistry And Tolerance Confirmation Before Supply
