Today, the use of metal products in the process of construction work is very relevant and appropriate. There are a number of structures, they are distinguished by type and place of application: - welded elements and structures (used in transport galleries, crane and beams at work sites, gussets, engineering systems, roofs, etc., that is, in places where conditions are difficult operation; - welded (for crossbars of frames, floor beams and coverings, bending elements), that is, where a static load is provided; - welded structures for racks, columns, compressed-bending elements, cover girders operating with a static load; - whole a number of additional elements for the construction of fences, foundations, pipes, communications.
About the use of alloys
Nickel silver is called "new silver ", it looks like it. The alloy has some unique properties, it can be processed by cutting, and soldered. Thanks to such indicators as strength, excellent manufacturability MNTs15-20 nickel silver alloy is considered very popular for the manufacture of flat semi-finished products (strips and strips), as well as rods, pipes and wires used on construction sites.
About types of broom properties
For the rational use of metal structures in construction, knowledge of the properties of the metal is required, they depend on many factors: This is the structure, composition and whether there is a mixture in the metal, since after passing through heat treatment, the structure can change, therefore, the properties. The requirements for alloys are quite high, especially in terms of resistance to temperature extremes, strength and the appearance of rust. The long service life of the construction site as a whole will depend on this.
The properties of metal and alloys are divided into the following types: - physical and mechanical indicators include indicators of endurance, elasticity, strength, toughness, hardness); - to technological (the possibility of forging, welding and stamping); - to chemical (the presence of resistance to acids, alkalis, water - sea and fresh, to humid air and gases at different temperatures).
Refractory metal alloys meet all of the above properties, they are used in the manufacture of fasteners that are required in construction. The reason for using these alloys is in their high qualities in terms of fracture and tear strength, springiness, resistance to oxidation and corrosion.
