Si Edward's original shop, 1925.

Edwards Heat Treating today. 

    In 1954, Si Edwards sold the heat treating business that he started in 1925 to two of his partners. It had long been Si's dream to start another heat treating business from scratch, with all brand new electric atmosphere furnaces in a brand new building where the equipment could be placed in the most convenient locations. That dream, which was shared by sons Don and Bill, became a reality in early 1956, when the plans were finalized and furnaces were purchased and Edwards Heat Treating Service became a California corporation. The first heat treating job was entered on the books in October 1956. Sadly, in February 1961, Si Edwards passed away.
    After 16 years in the 7,200 square foot building, additional space and equipment was needed; so in 1972, Don and Bill bought a 3/4 acre lot in a raw industrial area and laid out the plans for a 13,000 square foot building. Bill's son, Lee, joined he family business at this time to help in the awesome task of moving. Over the years, more furnaces and equipment were added and upgraded and now total 17 units and their related equipment.
    Edwards Heat Treating is located just 2 miles from the Oakland International Airport and a half mile from Interstate 880. This convenient location allows them to draw customers from all over Northern & Central California, Western Nevada and Southern Oregon.
    Edwards has been a proud member of the Metal Treating Institute since 1963. As a member, one of the most important and rewarding aspects, from our point of view, is the ability to meet together, discuss and swap ideas with heat treaters from all over the world. Very seldom has one of us come home from a meeting without some new idea to save money, a safer procedure or a better way to deal with governmental regulations.
    E.H.T. is a small company with only ten employees, but those ten account for over 248 years of heat treating experience. Specialties include close tolerance case hardening, induction heating and the heat treatment of tool steels. Customer companies range from small tool & die shops to large ones such as United Air Lines, Alaska Airlines, Aerojet and Peterbilt. Plastic mold dies, cotton picking spindles, gears and springs of all sizes and shapes, and metal forming roll dies are some of the various parts that are routinely heat treated at Edwards.
    Si Edward's legacy was to give the customer "what he wants, when he wants it and at a price that is fair and reasonable to both" is still very much in effect today. Due to Si's imagination, dedication and inspiration, the Company slogan will remain:
