Abstract

The utility model relates to an SUS444 ferrite stainless steel clad plate which is characterized by being provided with a double-layer clad plate, wherein one layer thereof is an SUS444 ferrite stainless steel plate, and the other layer thereof is a general steel plate. The SUS444 ferrite stainless steel clad plate can effectively compound the SUS444 ferrite stainless steel plate with the general steel plate, thus guaranteeing the clad steel plate to have the required strength in the premise of having all advantages of SUS444 ferrite stainless steel, and further saving the using amount of expensive metal. Simultaneously, the SUS444 ferrite stainless steel clad plate is extremely high in welding quality and guarantees long-term stable use without breaking off.

Description

SUS444 ferritic stainless steel clad steel plate

Affiliated technical field

The utility model relates to the metallic explosive composite plate.

Background technology

SUS444 (00Cr18Mo2) is a kind of Ultra-low carbon, contain 18% chromium and 2% molybdenum, high anti-corrosion ferritic stainless steel.This steel grade generally adopts niobium or titanium to carry out stabilisation, the intercrystalline corrosion after can avoiding welding.Compare with SUS316L with austenitic stainless steel such as SUS304, the sharpest edges of this steel grade are to have excellent anti-chlorine ion stress corrosion cracking ability, and the anti-chlorine ion spot corrosion ability of this steel grade is better than SUS304, and are suitable with SUS316L.Therefore, this steel grade is particularly suitable for being applied to various water treatment facilities.

SUS44 is owing to have These characteristics, so widely as the direct contact surface of container in the water treatment facilities or pipeline, but because the market price of SUS44 is higher, satisfy the needs of intensity again, so SUS44 and common metal composite need be used.

Explosion welding technique is the high-voltage pulse load that produces by explosive detonation, promote the another kind of material (base material) of a kind of material (multiple material) high speed inclined impact, its loading stress is higher than the yield strength of metal material far away, the moment property of loading procedure (generally with millisecond meter), the locality of material stand under load, interweaving occurs in the small adjacent domain of application point and mode such as moves at high speed, realizes the metallurgical binding of two kinds of metals, and the land is rendered as wavy metallurgical binding.Explosive welding is again the new and high technology a kind of of great practical value of carrying out the intermetallic welding and producing metallic composite as the energy with explosive.Its maximum characteristics are metallic combination to be welded together simple, rapid and strongly in moment.The advantage of comparing explosion welding technique with solder technology such as rolling, built-up welding, casting is:

Material adaptability and solderability are applicable to most ductile metal or alloy widely; Especially for the welding of large-area metal, can be described as unique method of attachment; Be not only applicable to the combination of intermiscibility metal, and be applicable to the combination of non-intermiscibility metal, be applicable to the metal and the alloy of compound between easy generation brittle metal yet; Have good thermal conductivity, low interface resistance, the land does not have the heat affected area and constitutes good joint performance, and the thermal process of moment does not have the interface or a spot of dissolving is only arranged.

Summary of the invention

The purpose of this utility model provides a kind of SUS444 ferritic stainless steel clad steel plate to remedy the deficiency of prior art.

The purpose of this utility model is achieved in that SUS444 ferritic stainless steel clad steel plate, it is characterized in that: be provided with double layer composite board, wherein one deck is the SUS444 ferrite stainless steel, and one deck is a general steel plate in addition.

Beneficial effect

The product that the utility model provides, can be effectively that SUS444 ferrite stainless steel and general steel plate is compound, thereby guaranteeing that clad steel plate has under the prerequisite of all advantages of SUS444 ferritic stainless steel, had the intensity of needs, thereby saved the use amount of expensive metal.This product has very high welding quality simultaneously, guarantees that steady in a long-term the use can not come off.

The utility model is further described by embodiment below in conjunction with accompanying drawing:
