It is one of the indexes of metal strength.
Galvanised sheet metal properties.
It is the maximum stress that the sheet metal material is subjected to before pulling out.
Steels galvanized steels and aluminum alloys are industrially important metals that are produced in large quantities.
Thus the tensile strength proof strength and tensile elongation of cold rolled steel were unaffected except that the tensile elongation of 40 cold rolled steel tended to be increased by galvanizing.
This is the most common use for galvanized metal and hundreds of thousands of tons of steel products are galvanized annually worldwide.
According to the american galvanizers association galvanized steel resists corrosion up to 100 times better than uncoated steel.
N mm2 or mpa the symbol is σb.
Of these materials the corrosion protection of steel is most challenging even if iron is more noble than zinc or aluminum 2 fig.
1 t bends in many of the steels were embrittled by galvanizing but galvanized 2 t and 3 t bends in all steels could be completely straightened.
The top countries of supplier is china from which the.
In developed countries most larger cities have several galvanizing factories and many items of steel manufacture are galvanized for protection.
