SiMn60-14 Product Overview
SiMn60-14 is a widely used standard grade of silicon manganese alloy, offering a balanced combination of manganese (60-63%) and silicon (14-16%). It serves as a reliable and economical deoxidizer and alloying addition in the production of carbon steels and low-alloy steels, ensuring clean metal and consistent mechanical properties.
Product Core Advantages
- Efficient Deoxidation: The combined action of silicon and manganese removes oxygen effectively, forming fluid and easily removable slag inclusions.
- Controlled Alloying: Provides stable manganese content for strength and hardenability, with moderate silicon for enhanced deoxidation.
- Cost-Effective: Economical choice for standard steel grades where ultra-high silicon or manganese is not required.
- Consistent Chemistry: Tight control over Mn, Si, C, P, S ensures predictable metallurgical results.
- Versatile Form: Available in lumps or custom sizes to suit different furnace additions and handling systems.
Typical Application Areas
Silicon Manganese 60-14 is commonly used in:
- Carbon Steel Production: For deoxidation and manganese alloying in plain carbon steels.
- Low-Alloy Structural Steels: Provides the required manganese content for strength.
- Reinforcing Bar (Rebar) Manufacturing: A standard addition for meeting rebar specifications.
- Foundry Operations: Used in cast iron to control microstructure and improve mechanical properties.
- General Engineering Steels: For applications requiring moderate strength and good weldability.

Application Guidelines
SiMn60-14 is a versatile alloy with the following applications:
Steelmaking Deoxidation
Added during the refining stage to remove oxygen. The silicon and manganese combine to form stable oxides that float out of the molten steel, resulting in cleaner metal.
Manganese Alloying
Provides the necessary manganese content to improve strength, hardness, and hardenability in carbon and low-alloy steels.
Foundry Castings
Used in cast iron to control graphite morphology and enhance mechanical properties like tensile strength and wear resistance.
Typical Addition Rates
Addition rates typically range from 2-5 kg per ton of steel, depending on target chemistry and initial conditions.

Frequently Asked Questions
Is it possible to entrust a third-party inspection to check the quality before shipment?
+
Certainly, we support third-party inspections by internationally recognized quality inspection agencies such as SGS and BV to verify product quality before shipment. The inspection covers product appearance, weighing, dimensions, and chemical composition analysis. The entire inspection process will be documented with photos and written records, which will be provided to you together with the final inspection report. This ensures you have no concerns regarding product quality.
What is the main difference between SiMn60-14 and SiMn65-17?
+
SiMn60-14 contains slightly lower manganese (60-63% vs 65-68%) and lower silicon (14-16% vs 17-19%), with a higher allowable carbon (≤2.5% vs ≤1.8%). It is a more economical choice for standard steel grades that do not require the higher alloy content.
Can you supply SiMn60-14 in customized lump sizes?
+
Yes, we can produce custom sizes such as 10-60mm, 10-80mm, or other fractions to meet your specific furnace charging requirements.
