In the stainless steel tube standard, brinell hardness is the most widely used, often to indentation diameter to express the hardness of the material, both intuitive and convenient. However, it is not suitable for hard or thin steel pipes.
Rockwell hardness
The Rockwell hardness test of stainless steel tube is the same as brinell hardness test, which is the indentation test method. The difference is that it measures the depth of the indentation. Rockwell hardness test is a widely used method at present, among which HRC is second only to Brinell hardness HB in steel pipe standard. Rockwell hardness can be applied to determine from very soft to very hard metal materials, it makes up for the Brinell method is not, is simpler than brinell method, can be directly from the hardness machine dial read hardness value. However, due to the small indentation, the hardness value is not as accurate as buchwald method.

Stainless steel export is an important part of China's export economy, it plays an important role in stimulating China's economic growth, but from the current situation of China's stainless steel foreign trade, China's stainless steel export encountered greater resistance.
Since last year, overseas frequently came to the stainless steel casting products in China "double reverse" message, it has a great influence for the stainless steel casting industry in China, and exports are a good portion of the stainless steel industry development in our country, in the development of the industry has a huge market share, in the face of the economic downturn, the development speed slow, Stainless steel industry development in our country should continuously improve product quality, better the development of overseas trade and against trade protectionism, the products and environmental protection, energy resources, humanities environment, enhance the competitiveness of the stainless steel products, only in this way can the indefectible position in the foreign trade.
