Surface treatments
Allegheny Surface Technology, established in 1993, is a leading provider of metal surface finishing services. Operating from a 24,000 square foot state-of-the-art facility, the company is renowned for its high standards in customer service, workmanship, and quick turnaround times. Their commitment extends to environmental responsibility, evidenced by an advanced wastewater treatment system.
Core Metal Finishing Services
Allegheny Surface Technology offers a comprehensive suite of metal surface finishing solutions. Electropolishing, an electrochemical process, removes microscopic imperfections, improves surface finish by up to 50% Ra, and enhances corrosion resistance. It is effective on 200, 300 series stainless steel, 17-4, 17-7, high nickel alloys, and duplexes, handling parts up to 20,000 lbs and large dimensions. The company also provides pickling for removing impurities and scale using acid immersion or paste, and passivation treatments (nitric, citric, or pickle passivation) to restore and enhance corrosion resistance by removing free iron. Mechanical polishing services, including grinding, buffing, and hand polishing, are available to achieve specific surface roughness requirements, even single-digit Ra readings.
Specialized Capabilities and Industry Focus
Beyond core finishing, Allegheny Surface Technology excels in specialized services such as pressure vessel modification and repair, holding an 'R' stamp certification from the National Board. Their extensive capabilities include various Non-Destructive Testing (NDT) methods like visual inspection, liquid penetrant testing, ultrasonic thickness testing, hydrostatic pressure testing, and positive material identification. The company offers on-site services for situations where equipment cannot be easily transported, including 24/7 rapid response for emergencies. They cater to a diverse range of industries, including pharmaceutical, chemical, food & beverage, electronic, architectural, automotive, aerospace, medical, semiconductor, nuclear, and wastewater treatment, ensuring compliance with standards such as ASTM, ASME BPE, and SEMI.
