Description

A kind of high-nitrogen austenitic stainless steel special welding wire
Technical field
The present invention relates to a kind of wire composition formula design, be specifically related to a kind of special welding wire formula for high-nitrogen austenitic stainless steel.
Background technology
As a kind of resource-conserving rustless steel, the research and development of high-nitrogen austenitic stainless steel tallies with the national condition, and has fully demonstrated the strategy of social sustainable development. though high-nitrogen austenitic stainless steel is succeeded in developing, but the solder technology adapted with it, especially high-nitrogen austenitic stainless steel welding very easily produces pore and embrittlement, be the difficult point in application. therefore the extensive use of high-nitrogen austenitic stainless steel is heavily dependent on its welding characteristic. in high-nitrogen austenitic stainless steel fusion process, the effusion that loss main manifestations is the formation of nitrogen pore and nitrogen of weld metal zone nitrogen. high-nitrogen austenitic stainless steel just has good performance due to higher nitrogen content, and in its fusion process, the loss of weld metal zone nitrogen reduces the solid solution nitrogen content in weld seam, thus causing the decline of joint performance, therefore, need to solve the loss problem of nitrogen during high-nitrogen austenitic stainless steel melting welding. during 12, although having carried out high-nitrogen austenitic stainless steel through engineering approaches applied research, on the welding procedure basis of conventional armor steel, found out high-nitrogen austenitic stainless steel can through engineering approaches application welding technique, tentatively solve its solderability problem, but owing to there is no high-nitrogen austenitic stainless steel special welding wire, it is not solved by the loss problem of nitrogen, its property of welded joint does not find full expression, therefore, need according to high-nitrogen austenitic material metallurgical characteristics and property of welded joint requirement, research weldering welding material alloy system composition butt welded seam nitrogen content, the impact of gas porosity and tissue, analyze the Nitrogen action in weld seam when different soldering wire alloy component, carry out welding point weldability matching correct and preferred, mix high-nitrogen austenitic stainless steel special welding wire chemical composition, by smelting, rolling, draw and the operation such as dial and develop the welding material of applicable high nitrogen steel.
Summary of the invention
The present invention, by providing a kind of special welding wire suitable in nitrogen content at the high-nitrogen austenitic stainless steel 1Cr22Mn16N of 0.3%-0.6%, solves the loss problem of nitrogen during high-nitrogen austenitic stainless steel welding.
The present invention is realized by techniques below scheme:
A kind of high-nitrogen austenitic stainless steel special welding wire, consists of the following composition (percentage by weight):

The special welding wire of the present invention, by good joint performance coupling, it is possible to play the premium properties of high-nitrogen austenitic stainless steel comprehensively.
Detailed description of the invention
The present invention is a kind of special welding wire suitable in nitrogen content at the high-nitrogen austenitic stainless steel 1Cr22Mn16N of 0.3%-0.6%, consists of the following composition (percentage by weight): C��0.05, Si0.20��0.60, Mn3.50��4.50, P��0.015, S��0.015, Cr20.0��22.0, Ni9.0��10.5, Mo1.50��2.50, N0.20��0.30, V��0.25, Nb��0.10, all the other are Fe. After smelting, dish processed circle, make finished product welding wire through multiple tracks drawing. Deposited metals mechanical property: tensile strength >=750Mpa, yield strength >=530Mpa, elongation percentage >=30%, ballistic work >=110J;
Embodiment
Prepared by �� 1.2mm height nitrogen special welding wire:
Chemical analysis: %
Forge pressed discs circle after smelting, after 3 passage annealing drawings, make �� 1.2 finished product welding wire. Welding cladding Metal Mechanic Property: tensile strength 780Mpa, yield strength 550Mpa, elongation percentage 35%, ballistic work >=115J; The joint performance of welding 1Cr22Mn16N high nitrogen stainless steel is: tensile strength 905Mpa, elongation percentage 40%, heat affected area ballistic work >=120J, joint x-ray detection I level, significantly overcomes the weld porosity problem being difficult to avoid that in high nitrogen steel welding.
The present invention, by carrying out welding wire chemical analysis design, increases 0.2%-0.3%N on Cr-Mn-Ni-N alloy system basis, by reasonable component proportioning, prepares finished product welding wire through smelting drawing. High-nitrogen austenitic stainless steel postwelding weld seam ferrite content 5-8%, weld seam nitrogen porosity significantly reduces, and weld strength, joint toughness relatively conventional armor steel special stainless steel welding wire significantly improves. This welding wire can significantly inhibit the formation of nitrogen pore during high nitrogen steel welding, it is provided that a kind of high-quality welding material being suitable for high nitrogen steel.
