Steel Bars Combine Forging and Rolling

Scot Forge’s Tartan Bars feature a fully consolidated forged center, and a surface that is finished by multiple-pass rolling. Combining forging and rolling cuts press time in half; produces short runs in short order.

Scot Forge Difference

At Scot Forge, we know the importance of getting your parts on-time, as expected. However, for customers new to procuring forgings, ordering a forging that will meet all specifications for end-use applications may be a challenge, which is why finding a trusted supplier and partner is essential. Our employee-owners are here to ensure your project stays on track with our forgings by offering:

Quality Assurance

Scot Forge is proud to be ISO 9001:2015 and AS9100D certified, and our team is committed to providing outstanding customer satisfaction. Further pursuance of aerospace products has led to NADCAP accreditation in both Heat Treatment for nickel material and Nondestructive Testing.  

Every Scot Forge customer gets placed with a qualified team that will guide each nickel forging delivered from the inquiry stage to order placement, expediting and shipping.

Forged Products

We offer many size forgings in both standard and unique geometries to meet your needs.

Pro Tip - Did you know near-net shapes can save you time and money? Oftentimes, a customer calls to order a disc, which they will later machine down to a more shaped part. By working with our technically trained sales team you can get as close to your finished product shape as possible to optimize your production process.
