UNS N06600 Alloy 600 is a nickel-chromium-iron solid solution strengthened alloy with a nominal chemical composition of 72% nickel, 16% chromium, and 8% iron. Alloy 600 offers good corrosion resistance in many media with superior oxidation resistance at elevated temperatures.

UNS N06255 Alloy 2550 is a cold hardened nickel-based alloy intended for corrosion resistance to highly sour (H2S) environments with high chloride content, requiring high strength up to 400°F. It is commonly used for downhole tubular components in severely sour wells with high-pressure and high-temperature (HPHT) conditions, saltwater injection wells, and Acid Gas Injection (AGI) wells.

Nickel Base Alloys are used primarily in sour environments where the partial pressure of H2S exceeds 3 psi. Their useful range of temperature, H2S, and chlorides is extended by increasing additions of Nickel, Molybdenum, and other elements. These alloys are approved for highly sour environments in accordance with NACE MR0175/ISO 15156.

Harvey Construction, located in Hunt Valley, Maryland was established in 1961 by Frank M. Harvey, Sr.  The firm pursued and successfully completed several projects to commence what has become six decades of family pride and quality in construction.  We’ve been fortunate to have constructed several familiar landmarks in the area from highly detailed historic renovations to large warehouse complexes. Our range of construction includes renovations, new churches and schools, office buildings, gas stations, convenience stores, retail, tenant fit-outs and warehouses.  Harvey Construction has maintained a level of excellence and trust that has enabled the company to flourish and establish very deep roots in the community.  Our reputation has enabled the company to continue relationships with the Archdiocese, Developers and Architects that were established over sixty years ago. The late Frank M. Harvey, Sr., founder, was brought to Baltimore in 1953 from Boston, Massachusetts to serve as the Architectural Project Manager for Maginnis, Walsh & Kennedy, the Architectural firm that designed the Cathedral of Mary Our Queen.  At the completion of the project, Frank M. Harvey, Sr. realized his desire to continue working in the construction industry in Baltimore and henceforth, F.M. Harvey Construction Co., Inc. was formed and continues to grow with pride and integrity under the direction of his son, Frank M. Harvey, Jr. Currently, F.M. Harvey Construction is owned and operated by Frank M. Harvey.  Frank has been with the firm since 1984 and has presided over the firm as president since 1992.  Frank’s career spans more than 30 years, primarily in the commercial construction industry. Working summers during high school as a construction laborer, Frank understood at an early age the value of hard work and the critical importance of paying attention to details. Prior to graduating from the University of Richmond, Frank worked at almost every level of the construction industry, providing extensive training for his career in construction. Following graduation in 1984, Frank joined the family owned F.M. Harvey Construction Company. During his tenure, Frank has managed a variety of new construction and tenant improvement projects for customers in financial services, education, medical, residential, hospitality and religious services; covering commercial office, industrial and retail projects. The expertise of Harvey Construction also extends to design build services and construction management. Harvey Construction is proud of all of its employees and takes great pride in the formation of our team.  This is reflected in the products we deliver as well as the manner in which they are delivered.

UNS N06625 Alloy 625 is a nickel-chromium-molybdenum solid solution strengthened alloy with a nominal chemical composition of 61% nickel, 22% chromium, and 9% molybdenum. Alloy 625 provides superior corrosion resistance in aggressive environments coupled with excellent strength and weldability.

Our entire team feels a sense of responsibility to give back to the communities in which we live and work. We are very proud to provide ongoing support to Baltimore based non-profit G.B. Charities. Since 1991, GBC has raised over $1.5 million and funded scholarships for more than 60 promising students in the Baltimore area to attend the quality faith-based schools of their choice.

UNS N08028 / Alloy 28 28 Chrome is a cold hardened nickel-based alloy intended for corrosion resistance in highly sour (H2S) environments with moderate chloride content, requiring high strength up to 350°F.

UNS N10276 Alloy C276 is a nickel-chromium-molybdenum solid solution strengthened super-alloy often used in extremely corrosive environments that other alloys cannot withstand. The nickel, chromium, and molybdenum found in Alloy C276 form a powerful triple threat against almost all forms of corrosion.

For over six decades, our firm has been committed to providing our clients with the highest quality construction. We have a passion for solving life-size puzzles using creativity, hard work and teamwork. Founded by Frank M. Harvey, Sr. and currently owned and operated by Frank M. Harvey, Jr., we’re driven to be one of Maryland’s premier commercial construction firms.
