Carbon & Engineering Steels

Stop Gambling on Commodity Steel.

Inconsistency in your foundational carbon steel isn't a simple variance; it's a hidden tax that multiplies down your entire production line—costing you machine time, tool life, and customer trust.

Engineered for Critical Performance

These grades are the bedrock of your operation, but they are also a common point of failure. A supplier who treats them as a commodity is gambling with your time, your money, and your reputation. We see these grades not as a starting point, but as the first line of defense against operational failure, engineered with four key characteristics in mind:

Guaranteed Hardenability

Eliminate the risk of entire batches being rejected after heat treatment.

Reduced Tool Wear

Our consistent material structure prevents the excessive wear that damages expensive tooling.

Flawless Machinability

Machine with confidence, knowing our bars are free from hard spots and impurities.

Application-Ready

The versatile foundation for critical components, from shafts to fasteners.

The Marbrite Standard for Carbon Steels

Our standard exists to prevent the nightmare scenario: a batch of steel that fails to achieve the required hardness after you've invested hours of irreplaceable machine time. This isn't just a loss; it's a fundamental failure of your supply chain. The Marbrite Standard is our non-negotiable discipline. We deliver fully traceable material with a guaranteed MTC, ensuring the absolute chemical accuracy your process demands. This isn't a promise; it's the only way to do business.
