Acrylic Bathtub VS Fiberglass Bathtub. Both fiberglass bathtub and acrylic bathtub are the two most common bathtubs in the market. They are both molded plastic bathtubs. Acrylic bathtub has fiberglass in it, and fiberglass bathtub is made from more than just fiberglass.
Cold-formed steel (CFS) is the common term for products made by rolling or pressing steel into semi-finished or finished goods at relatively low temperatures (cold working).
Tool Steels are produced in the annealed condition for ease of machining. After machining, the steel is heat-treated and quenched depending upon the type of steel being used. The heat treating and quenching operations increase the toughness and strength of the material. There are three classes of tool steel generally available in the market today - cold work, hot work, and high speed steel: Cold Work steels have high strength, hardenability, impact toughness, and wear resistance.
