Description
Technical field
The present invention relates to scaling powder technical fields, and in particular to one kind 400 is ferritic stainless steel activated rosin flux.
Background technology
Stainless steel is the abbreviation of stainless acid resistant steel, the weak corrosive medium such as resistance to air, steam, water or the steel grade with rustless property
Referred to as stainless steel；And the steel grade that medium resistant to chemical etching (chemical etchings such as acid, alkali, salt) corrodes is known as acid resisting steel.Due to two
Difference of the person in chemical composition and keep their corrosion resistance different, generally resistant to chemical media corrodes common stainless steel, and resistance to
Sour steel then generally has rustless property.Stainless steel does not refer to a type of steel not instead of singly, indicates that more than 100 kinds of industry is stainless
Steel, each the stainless steel capital developed are with good performance in its specific application field.Stainless steel has hardness height, wear-resisting
Good, the good corrosion resistance of property, the characteristics such as excellent appearance and long lifespan are therefore widely used in building, auto industry, make
The industries such as ship industry, marine device, mechanical equipment and chemical device.
400 be the alloy that stainless steel is a kind of iron, carbon, chromium.This stainless steel has martensitic structure and ferro element, therefore
With normal magnetic characteristic.400, which be stainless steel, has very strong oxidation-resistance property, and compared with carbon steel, physics is special
Property and mechanical property have further improvement.Common 400 be to have 430 types containing chromium 18% in stainless steel kind and contain chromium
The 13% stainless steel pattern number of 410 types and 420 class, wherein the stainless steel pattern number usage amount of 430 types is maximum.400 the characteristics of being stainless steel
It is cheap, coefficient of thermal expansion is small, resistance to chloride stress corrosion better than 300 is stainless steel kind；But shortcoming
It is that forming property, solderability and tensile strength are less than the stainless steel pattern number of 304 types, it is therefore, limited using field.In chrome content
Under same case, in the Oxidant as in air, fresh water and nitric acid, 400 be stainless steel kind corrosion resistance and 300
It is that stainless steel kind is identical, 400 be that stainless steel kind is currently fed trace niobium, titanium, copper and aluminium element and can improve its deep drawing quality
Energy, solderability, corrosion resistance and high temperature resistance intensity can partly replace the stainless steel pattern number of 304 types.
400 be stainless steel in the welding process, seam crossing will produce partial saturation by 1000 DEG C of Source,
Then martensitic structure can be formed in grain boundaries during being quickly cooled down, and the coarse grains of intergranular can be caused, and made
Obtaining weld material embrittlement and toughness reduces, and the final welding quality for influencing seam even will produce crackle when serious.In addition,
The high temperature of welding also results in the carbon of ferritic stainless steel, nitrogen compound is precipitated, and intercrystalline corrosion tendency is reinforced so that seam crossing material
There is chromium depletedization in material, and the corrosion resistance of material reduces, that is, generates sensitization.
There is this problem in the use of most of welding auxiliary agent currently on the market, routinely improve the weld defect
Method is to be preheated before welding, carries out the heat treatment such as being tempered after welding, and needs to select high chromium-nickel austenite stainless
Steel welding wire.

Degree.Potassium fluoborate can improve slag fluidity, adjust the angle of wetting between weld seam and base material, while potassium ion therein is also steady
The effect of arc.Alloy powder, chrome green and nitrogen titanium aluminide three can generate synergistic effect, for adjusting weld metal
Corrosion resistance and toughness of material have remarkable result.
In addition, the heat absorbent in component can absorb partial heat in welding except initial stage, avoid welding except material temperature is fast
Speed increases, and prevents crystal phase structure from occurring excessively to change, after welding, can also discharge partial heat, avoid weld seam temperature
It quickly reduces, the problem of embrittlement is reduced with toughness is easy so as to improve weld seam.
S elements can cause grain boundaries that FeS is precipitated in commissure, and form eutectic with FeO, or form oxysulfide, carbon
Sulphur compound etc., these can all cause the corrosion resistance of seam and toughness to reduce；The effect of P is similar with S, therefore tight in solder flux
