Retardation

แปลว่า(Concrete Engineering) Delaying the hardening or strength gain of fresh concrete, mortar or grout.

Bright Basic Wire

แปลว่า(english) Bright steel wire, slightly softer than Bright Bessemer Wire. Used for round head wood screws, bolts and rivets, electric welded chain, etc.

Aging 1

แปลว่า(english) A change in the properties of certain metal and alloys (such as steel) that occurs at ambient or moderately elevated temperatures after a hot working heat treatment or cold working operation. Typical properties impacted are hardness, yield strength, tensile strength, ductility, impact value, formability, magnetic properties, etc. See also Non-aging.

Retempering

แปลว่า(Concrete Engineering) The addition of water and remixing of concrete which has started to stiffen: usually not allowed as it may affect the ultimate strength.

BOLT KIT

แปลว่า(english) A set of bolts or screws that ore selected to suit a particular application, i.e. pre-selected length, threads and strength to match the mounted component.

Bentonite

แปลว่า(english) A colloidal clay derived from volcanic ash and employed as a binder in connection with synthetic sands, or added to ordinary natural (clay-bonded) sands where extra strength is required.

Base Metal

แปลว่า(english) (1) The metal present in the largest proportion in an alloy; (2) the metal to be brazed, cut or welded; (3) after welding the part of the metal that was not melted during the process.

Bake Hardenable Steel

แปลว่า(english) A cold-rolled, low-carbon sheet steel used for automotive body panel applications. Because of the steel’s special processing, it has good stamping and strength characteristics and after paint is baked on, improved dent resistance.

Yield stress:

แปลว่า(english) A material loaded beyond its yield stress, no longer exhibits linear elastic behavior. Metals, particularly mild steel, generally have a very well defined yield stress compared to other materials. Yield stress is sometimes called yield strength.

Brasses

แปลว่า(english) Copper base alloys in which zinc is the principal alloying element. Brass is harder and mechanically stronger than either of its alloying elements copper or zinc. It is formable and ductile; develops high tensile strength with cold-working and is not heat treatable.

Boron (chemical symbol B)

แปลว่า(english) Element N. 5 of the periodic system. Atomic weight 10.82. It is gray in color, ignites at about 1112 (degrees) F. and burns with a brilliant green flame, but its melting point in a non-oxidizing atmosphere is about 4000 (degrees) F. Boron is used in steel in minute quantities for one purpose only- to increase the hardenability as in case hardening and to increase strength and hardness penetration.

Age Hardening

แปลว่า(english) Hardening by aging, usually after rapid cooling or cold working. The term as applied to soft, or low carbon steels, relates to a wide variety of commercially important, slow, gradual changes that take place in properties of steels after the final treatment. These changes, which bring about a condition of increased hardness, elastic limit, and tensile strength with a consequent loss in ductility, occur during the period in which the steel is at normal temperatures.
