Abstract
A kind of two phase stainless steel as welding material, its Main Ingredients and Appearance include following components（Represented with wt.%）：Ni 70-75%, Cr13-18%, Fe 6-12%, RE 0.5-2%, Mn≤1%, C 0.05-0.08%, Cu 0.3-0.5%, Si. 0.2-0.5%, Ti0.1-0.3%, A1 0.1-0.3%.The present invention, due to improve the content of Cr and Ni, greatly strengthen its corrosion-resistant and strength character, improve service life of the welding material in two phase stainless steel welding.
Description
Technical field
The present invention relates to stainless steel making field, especially with respect to a kind of two phase stainless steel as welding material.
Background technology
The comprehensive mechanical property of two phase stainless steel tubing is excellent, and with higher intensity and fatigue strength, its yield strength is the twice of 18-8 steel；In the operating mode of chloride ion high concentration, there is such as in high temperature seawater/high-temperature chlorine compound solution excellent resistance to pitting/resistance to corrosion at a seam/stress corrosion resistant ability；Its welding region hot cracking tendency is less, and solderability is good.The two-way rustless steels of Ocr25Ni6Mo3CuN are developed by SUMITOMO CHEMICAL metal industry company in 20 century 70s, the characteristics of steel grade is in Gao Ge, add tungsten on the basis of molybdenum, the elements such as copper are in order to improving the slit and corrosion resistant performance of steel, it is adapted to hot sea water, the ambient conditions such as bittern water, compared with 300 series austenitic stainless steel, there is high intensity, good plasticity and formability, there is outstanding local corrosion performance, it is the material of a resistance to neutral chloride local corrosion, ASTM standard has been included, A790 standards, and UNS standards are listed in the S31260 trades mark, and be applied successfully on the part such as sea water heat exchange and hot bittern water axial-flow pump.But the price of the steel is higher, the timeliness set sample SCC resistance of steel can be poor.
Content of the invention
It is an object of the invention to provide a kind of two phase stainless steel as welding material, be Ocr25Ni6Mo3CuN two-way stainless on the basis of, add the addition of rare earth material and control copper so as to more preferable mechanics and corrosion resistant welding material, to improve lumber recovery.
