Due to the lack of access to electric power, the equipment is 25 ma, as well as the lack of equipment available in it (2-3) and

the metal is not alloyed by omega and has a slight increase in the percentage of molybdenum and vanadium. Β In connection with this, the produced weld metal is deficient in 30 high speed and wear resistance.

However, in the event of an occurrence of less than 8

30 It ensures that all listed properties are completely free, and above $ 1 is also undesirable, as well as it doesn’t change at all. It is still Jewish that alloying fused metal with molybdenum, in contrast to other alloying elements,

35 has a strong effect on the stability of profitability and retirement. It also notifies primary and hot harshness, and, consequently, it is less troublesome, has a greater effect on the increase in dis- persion speed. - 3 - to increase the primary and impact viscosity of the weld metal.

On the other hand, these properties are most fully manifested when at least 8 are in possession of at least 5 in addition to other indigenous amber species. The availability of feribulide in arsenals for more than $ 12 is inappropriate, as well as the convenience of the melted metal increases insignificantly. Alloying of the deposited metal with vanadium, sulfur

For people living in the form of physical vanadium, they also exist for the purpose of improving high speed and ease of use. This is due to the formation and distribution of vanadium in the dispersion of finely dispersed and conventional carbides. Moreover, the higher the tempering temperature, then

15 more vanadium vanishes in austenit. After tempering and the release of carbide, vanadium is released from the substance in the form of finely divided phases, creating _" so-called secondary crashes, and increases the speed." Κaρbids of vanadium, πο equal to

20 karbidami other alloying elements, have a higher reliability, and therefore they greatly increase the resistance to fused metal. A very valuable property of vanadium is its ability to grind grain and to prevent the growth of grain from the gap

25 heating of the metal at the time of hardening. Canada also increases the intrinsicity and viscosity of the fused. metal. However, the most complete effect of vanadium doping is achieved when at least 4 of the vanadium is prevented, it is at least 4 and the best

30 additional components. With the onset of eruption of vanadium in the presence of more than β $, the growth rate of growth does not increase significantly. The presence of physical violence in the area is due to the fact that there is an increase in the size of the heated bath in the brown water, which is maintained in the area of security. Dark, κρome this, increase-

35 There is a general property, wear resistance and impact toughness of the melted metal.

The investigation of this thermal stability of fused metal, which is alloyed by the brown, is also increasing. The optimal properties of the fused metal, the right of the owner of the battery, the fixed circuit of the friends and the other 5 are impaired are protected. When the ferrous silica is contained, less than 4 is not achieved by the complete lightening of the bed, and if the price is more than 8 $, the load is not relieved.

10 In order to reduce the sensitivity of the metal, it must be kept at a safe temperature while keeping the tempered metal at a low temperature. Legation of titanium gives you the opportunity to without loss of mechanical properties and construction

15 places of the deposited metal to increase almost 50 ° C tempering tempering. In this case, it is converted to a significant amount that is significantly more difficult to displace in vanadium, and is also subject to an increase in consumption.

The most complete depletion and receipt of a flat fused metal is achieved if there is a complex

Organic manganese is also a desulphur, which contributes to a decrease in sulfur content in the melted metal and reduces its confinement to waste products.
