METALS THAT COMPARE TO STEEL

                                  STEEL

                                                   STEEL IS AN ALLOY OF IRON 
STEEL IS THE WORLD'S MOST IMPORTANT ENGINEERING AND CONSTRUCTION MATERIAL

                                COPPER

KEY ATTRIBUTES OF COPPER IS CORROSION RESISTANCE
AND ITS KILLS 99%OF GERMS
ITS COMMONLY USED APPLICATIONS LIKE MOTORS
ELECTRICAL WIRES

BRASS 

MAIN ALLOYING ELEMENT IS ZINC
COLOUR RANGES UP-TO RED IF ZINC IS APPLIED MORE ON THE MATERIAL 
ZINC CONTENT 
32-29% INCREASE WORKING ABILITY IN HOT CONDITION
BUT LIMITED COLD WORKING

OVER
 39%HIGHER STRENGTH LOWER DUCTILITY

BRONZE

BRONZE IS A COPPER ALLOY WITH THE MAIN ELEMENTS BEING TIN AND CONTAINS OTHER ELEMENTS LIKE PHOSPHORUS ALUMINIUM ETC
WE CAN IDENTIFY THE BRONZE WITH COLOR LIKE DULL GOLD
ON THE SURFACE THE FAINT RINGS RESULT OF BEING CENTRIFUGAL CASTED
BECAUSE OF ITS LOW METAL ON METAL FRICTION

WROUGHT IRON 

THE PUREST FORM OF IRON PRODUCED WHEN IMPURITIES ARE REMOVED IT CONTAINS 0.5%IMPURITIES

CAST IRON

ITS IS THE LEAST PURE OF ALL FORMS

ALUMINUM

ALUMINUM COMMONLY USED IN MANUFACTURING OF MARINE HARDWARE AND PUMPS

Steel Erection, Fabrication and Hybrid construction -Blog 16

Image
This blog is about how the steel sections are transported to the site, the issues involved with transportation, erection and fabrication along with the onsite constrains. TRANSPORTATION: The steel sections have to transported from the manufacturing site to the fabrication site and this becomes a tough task due to their size. Often large pieces cannot be transported in a single part, they are split or divided and shipped as two separate pieces or even as one piece to avoid damage or scratches. Temporary connections are made on the pieces to avoid damage and to keep the parts in place during transportation.     These parts are not transported in normal vehicles but require long trail vehicles to fit their length and size which again becomes a difficult task to turn around the corners of the road and at junctions     FABRICATION & ON SITE CONSTRAINS: Fabrication of steel on sites which are along the main road or at the corner site is very hectic as there is very...

BLOG-16 FABRICATION, ERECTION AND HYBRID STRUCTURES

Image
  FABRICATION: The process of  steel fabrication  involves grinding, welding, cutting, bending, drilling, punching, burning or melting and other general crafting methods using various high-quality tools and CNC equipment. ERECTION LIFTING, POSITIONING AND PLACING OF STEEL MEMBERS IN A STRUCTURE  Once the member(s) are lifted and placed in the required place, with the help of temporary supports and equipment, they are fastened and fixed, depending on the nature of connection.  Erections may be achieved by two techniques such as MEWP(Mobile Elevating Work Platforms) by Mobile crane and Tower cranes. HYBRID STRUCTURES Hybrid structures are structures built with composite materials a combination of different materials with steel. A common  hybrid system  consists of hollow core slabs together with steel or cast-in-situ concrete frames                       EXAMPLE STEEL WITH TIMBER     I...

BLOG- 8                                     STEEL , ALLOYS AND THEIR COMPARISON                                                               STEEL AND ALLOYS                                               An alloy is a blend consisting of metal and other elements. Alloys are generally made for achieving properties like greater strength or resistance to corrosion. Steel is an alloy of iron. It mainly consists of iron with some small amounts of carbon. Definition ALLOY :      A homogeneous mixture of a metal with other types of elements                       ...
