Environment-friendly stainless steel electrode component

Abstract

The invention discloses an environment-friendly stainless steel electrode component which consists of the following ingredients in parts by weight: 4-8 parts of silicon, 3-6 parts of nickel, 5-10 parts of manganese, 5-10 parts of carbon, 3-8 parts of ferrotitanium, 5-7 parts of pyroxene, 10-20 parts of mica and 2-5 parts of electrolytic manganese. The environment-friendly stainless steel electrode component is capable of resisting oxidation corrosion at a higher temperature, is wear-resistant and modification-resistant, and has higher mechanical strength, high elongation, favorable formability and favorable weldability.

Description

technical field [0001] The invention belongs to the field of welding materials, in particular to an electrode, in particular to an environment-friendly stainless steel electrode component. Background technique [0002] At present, the A101 electrode required by the domestic and foreign markets is often replaced by A102. The specifications of A102 commercially available products are generally ￠2-￠5mm, which are mainly suitable for the welding of thick stainless steel structures such as OCr19Ni9 and OCr19Ni11Ti and the welding of pressure vessels. At present, there are still deficiencies such as poor welding process performance, porosity sensitivity, crack sensitivity, and large spatter affecting the appearance of weldments. A101 stainless steel welding rods of the same type at home and abroad are usually designed with low alkalinity and high Si content in the deposited metal in terms of coating formula design, which can easily lead to weld porosity sensitivity and crack sensi...

Problems solved by technology

[0002] At present, the A101 electrode required by the domestic and foreign markets is often replaced by A102. The specifications of A102 commercially available products are generally ￠2-￠5mm, which are mainly suitable for the welding of thick stainless steel structures such as OCr19Ni9 and OCr19Ni11Ti and the welding of pressure vessels. At present, there are still deficiencies such as poor welding process performance, porosity sensitivity, crack sensitivity, large spatter affecting the appearance of weldments, etc.

A101 stainless steel welding rods of the same type at home and abroad are usually designed with low alkalinity and high Si content in the deposited metal in terms of coating formula design, which can easily lead to weld porosity sensitivity and crack sensitivity, followed by slag The melting point, viscosity, surface tension, fluidity, wettability and other aspects are also unsatisfactory, and it is difficult to meet the higher requirements of all-position welding performance, which is even more important for decoration projects
