Effects of Alloy Elements in Steel ( to be used as a general guide only)
- Carbon (C) - improves hardenability, strength, and hardness and wear resistance but reduces ductility, weldability and toughness.
- Manganese (Mn) - improves hardenability, strength, abrasion resistance and machinability; deoxidizes the molten steel and reduces and decreases weldability.
- Phosphorus (P) - improves hardenability, strength, corrosion resistance, and machinability; severely reduces ductility and toughness.
- Sulfur (S) - improves machinability when combined with manganese; lowers impact strength and ductility; impairs surface quality and weldability.
- Silicon (Si) - improves strength, hardness, corrosion resistance, and electrical conductivity; decreases machinability and cold formability.
- Chromium (Cr) - improves toughness, hardenability, wear and corrosion resistance and high-temperature strength. Also increases depth of hardness penetration in heat treatment by promoting carburization.
- Molybdenum (Mo) - improves hardenability, wear resistance, toughness, elevated temperature strength, creep resistance and hardness; minimizes temper brittleness.
- Nickel (Ni) - improves strength, toughness and corrosion resistance; improves hardenability.
- Copper (Cu) - improves resistance to atmospheric corrosion and strength with little loss in ductility; adversely affects hot working characteristics and surface quality.
- Vanadium (V) - improves strength, toughness, abrasion resistance and hardness at elevated temperatures; inhibits grain growth during heat treatment.
- Cobalt (Co) - improves strength and hardness at elevated temperatures.
- Boron (B) - improves hardenability without loss of machinability and formability.
- Titanium (Ti) - improves hardenability; deoxidizes steels.
- Columbium (Cb) - imparts fine grain size, improves strength and impact toughness; decrease hardenability
- Selenium (Se) - improves machinability.

Patriot Forge is equipped to deliver the highest quality components on a consistent and reliable basis. We are continually working to improve our Quality Assurance and Quality Control Processes. If you have a specific quality related issue you would like to commiunicate, please contact us.
Testing
Non-Destructive
Complete in-house non-destructive testing facilities allow us to perform Ultrasonic, Liquid Penetrate, and Boroscopic Inspection & Magnetic Particle Inspections. Our team of NDE technicians is
Qualified up to and including Level III UT, PT, MT – Canadian General Standards Board (CGSB) certified and qualified under ASNT-TC-1A and NAS 410.
Patriot can also offer in-house PMI testing with the NITON XLP 818 X-ray Spectrometer.
Destructive
Patriot offers a full range of destructive testing through independent ISO 17025 accredited and/or NADCAP approved laboratories.
Coordinate Measuring Machine Inspection (CMM)
Patriot offers in-house (CMM) dimensional inspection to validate product to .0001” accuracy. Our custom Calypso software allows for extremely accurate curve measurement of turbine disks.
Tracking/Traceability
Bar Code
- Barcode scanning of shop travelers throughout every stage of manufacturing allows for up-to-the-minute status checking/reporting of every order in each manufacturing facility.
Heat Treat
- automatic furnace charting
- mapping of components on all heat treat loads
- all heat treat furnaces are microprocessor controlled. Once the thermal process is defined, it can be locked in & replicated for every future order.
Raw Material
- Strictly maintained throughout every stage of our Manufacturing process. Patriot maintains an extensive inventory of raw material, primarily from domestic sources. Chemistries are specifically chosen by our team of on-staff metallurgists to meet all ASME codes from 1970 to present. Our metallurgists routinely perform in-depth reviews of proprietary customer specifications in order to design manufacturing processes that will consistently meet all requirements. Once a process is defined, it becomes a locked and controlled process, allowing for consistent repeatability.
