Boron Steels

แปลว่า(english) The addition of boron in the range 0.0005-0.005% to certain steels increases the hardenability. A range of boron steels is now listed in the current BS 970 and are widely used for the production of cold headed fastenings.

division

แปลว่าการแบ่ง, ส่วนแบ่ง, ชั้น, แผนก, กอง Division of Designs and Contruction = กองออกแบบ และก่อสร้าง Division of Engineering = กองช่าง Division of Forest Control = กองคุ้มครองป่าไม้ Division of Waterways Maintenance = กองขุดและรักษาร่องน้ำ

Blue Annealing

แปลว่า(english) Heating hot rolled ferrous sheet in an open furnace to a temperature within the transformation range and then cooling in air, in order to soften the metal. The formation of a bluish oxide on the surface is incidental.

Colloids

แปลว่า(Environmental Engineering) Small particles which have a negligible settling velocity. These particles have a very small mass so gravitational force is low compared to surface frictional forces. Typical colloidal sizes range from 10-3 mm to 1 mm.

Corrosive waste

แปลว่า(Environmental Engineering) A waste that is outside the pH range of 2 to 12.5 or a waste that corrodes steel at a rate greater than 6.35 mm (0.25 in) per year. One of EPA's four hazardous waste properties.

Blue Brittleness

แปลว่า(english) Brittleness exhibited by some steels after being heated to some temperature within the range of 300 (degrees) to 650 (degrees) F, and more especially if the steel is worked at the elevated temperature. Killed steels are virtually free of this kind of brittleness.

Box Annealing

แปลว่า(english) Annealing a metal or alloy in a sealed container under conditions that minimize oxidation. In box annealing a ferrous alloy, the charge is usually heated slowly to a temperature below the transformation range, but sometimes above or within it, and is then cooled slowly; this process is also called close annealing or pot annealing.

Box Annealing 2

แปลว่า(english) A process of annealing a ferrous alloy in a closed metal container, with or without packing materials, in order to minimize the effects of oxidation. The charge is normally heated slowly to a temperature below the transformation range, but occasionally above or within it, and then is slowly cooled.
