In the late 1990s, a stainless steel material called J4 produced by an Indian company was introduced into China (also known as 201A in this article). Its low price suddenly attracted many stainless steel pipe welding enterprises and decoration manufacturers to produce and sell, but at that time there were very few manufacturers that provided this material. After that, some domestic private enterprises quickly found the business opportunity, and quickly invested in the production of this stainless steel material. Around 2006, the company stopped selling and supplying only a small portion of its panels in China, where the welded pipe industry has almost stopped using them.
