Stainless steel is greater than 12% chromium steels. Stainless steel has been made since the 1912 invention of the rapid development of the world still has a rate of 3-5% per year. The world's total consumption of stainless steel up to 35 million. China is in the application of stainless steel production and consumption of high-speed growth period, has been widely used in petroleum, chemical industry, light industry, food, wine, pharmaceutical, household appliances, utilities, machinery, construction, municipal and civil equipment in all. China's stainless steel consumption in 1990 was 26 million tons in 1999 to 153 million tons in 2000 is 173 million tons in 2001 to 225 million tons of stainless steel consumption in 2004 reached 4.47 million tons, ranking first in the world, Stainless steel consumption is expected in 2006 will reach 600 million tons, of which chromium-nickel austenitic stainless steel consumption accounts for 75% of total consumption to 80%.
China from the fifties, development and production of stainless steel welding, stainless steel electrode 1997, the total output of China's 7,000 tons. In recent years, China's rapid growth in steel consumption in 2004, has made more than 35,000 tons of stainless steel Welding Rod, made in 2006 is expected to reach 50,000 tons of stainless steel welding rod around.
Since the 1950s started to develop the stainless steel electrode, mainly followed the former Soviet Union titania slag and raw material system, it has a low cost, easy to press coating, anti-porosity, mechanical properties and good, but the stainless steel electrode with the same brand name in Europe compared to the red electrode serious, big splash, slag off poor and forming, welding, low efficiency, waste, so since the mid-seventies to early eighties, imports for the domestic Swedish company Green P5 electrode AVESTA some domestic research institutions together with the electrode manufacturer, welding on stainless steel skin redness loss drug causes and solution have been studied, such as Ha and welding the Welding Electrode Manufacturer in Tianjin, Gansu Industry University and Blue Island Changhong welding, the machine tool plant in Shanxi Taiyuan Institute of Technology and so on.
