It is convenient to observe the weld pool and whether it is fully welded; When the welding wire is filled, it shall be sent to 12 places of the molten pool and pressed inward slightly to ensure the penetration and prevent concave; During the welding process, the welding wire shall be regularly fed in and taken out, and the welding wire shall always be kept in the argon atmosphere

The representative steel SUS304 (18Cr-8Ni) of steel is non-magnetic at room temperature, but becomes magnetic at low temperature.

Nelspret.In order to obtain good corrosion and wear resistance, the combination of mechanical properties and corrosion resistance of stainless steel pipe materials should be considered. At present, and studied the austenitizing temperature and time,NelspretCold rolled precision stainless steel strip, tempering temperature,Nelspret316L stainless steel pipe factory,Nelspret316L high temperature resistant stainless steel belt, etc

Good economic benefits have been obtained by welding in the field.

.The oxide scale of stainless steel pipe becomes loose after pretreatment, and then it is easy to remove after pickling. Pretreatment can be divided into the following: alkaline salt melting treatment. The alkaline melt contains 87% hydroxide and 13% salt. The proportion of the two in the molten salt should be strict so that

It is divided into two steps, one is pretreatment, and the second step is ash removal.

The full name of 304 stainless steel pipe is SUS304 stainless steel pipe.

High frequency welding speed makes it difficult to remove the burr in the welded pipe. At present, the high-frequency welded stainless steel pipe can not be borne by the chemical and nuclear industries, which is one of the reasons.

The Chinese cold rolled non oriented silicon steel strip (sheet) indicates: dw+ iron loss value (at the frequency of 50Hz, the magnetic induction peak with sinusoidal waveform is 5T per unit weight iron loss value.) 100 times + 100 times the thickness value. For example, dw470-50 indicates that the iron loss value is 7w/kg,

The intergranular corrosion of austenitic stainless steel can be prevented by adding Ti Nb and other elements that can form stable carbides (tic or NBC) and avoiding the precipitation of cr23c on the grain boundary.

Welcome calls .In addition to black plating, water plating is also used. Other common stainless steel color plates will still choose electroplating and coloring.

A layer of coating is formed on the surface of Zifa stainless steel plate. Many stainless steel colors can be produced by vacuum plating. But the cost of production will be more expensive than that of water plating.

AUSTENITIC FERRITIC duplex stainless steel. It has the advantages of both austenitic and ferritic stainless steels and has superplasticity. Martensitic stainless steel. High strength, but poor plasticity and weldability.

Type a pipe is also a very competitive water supply pipe, which will improve water quality and improve people's life

Installation conditions.No. When the initial micro crack meets the ferrite phase it will not continue to expand, and the ferrite content should be about 6%.

Low temperature processing --- martensite series stainless steels are quenched from austenitizing temperature and then cooled to extremely low temperature to promote martensite quenching. Suitable for stainless steel easy to produce retained austenite.


Nelspret.Of course, the above is only common for coloring stainless steel plates. There are other popular ones. Welcome to leave a message!

Any steel with hollow section with openings at both ends and a large ratio between its length and section perimeter can be called steel pipe. When the length is smaller than the section perimeter, it can be called pipe section or tubular fittings, and the flux cored wire +tig process has been used for several years in China. Now, flux cored wires such as e308t1-e308lt1-e309t1-e309lt1-347t1-e316t1-e316lt1-1 have been produced and have been used in the current
