Description
TP347H STAINLESS STEEL PIPE SEAMLESS AND WELDED
tp347h stainless steel pipe is a brand of stainless steel manufactured according to the ASTM standard. tp347h stainless steel pipe s are equivalent to china 0Cr18Ni11Nb stainless steel pipe.
TP347H STAINLESS STEEL PIPE BRIF INTRODUCTION.
tp347h stainless steel pipe: chromium 18%, including nickel 11%
tp347h stainless steel pipe = 0Cr18Ni11Nb contains Nb, which increases the corrosion resistance of crystals and increases the strength and plasticity. Reduce the thickness of the material. As a structural strength component.
tp347h stainless steel pipe heat treatment: solid solution treatment (980-1150 ℃) cold fast
tp347h mechanical properties of austenitic steel of stainless steel tube with solid solution (GB/t4237-92)
Yield strength is greater than 205 / MPa, the tensile strength is greater than 520 / MPa, the elongation rate is greater than 35%, hardness test: HBS is less than 187, HRB is less than 90, HV is less than 200
tp347h stainless steel pipe chemical composition: C is less than 0.08, Si less than 1.00, Mn is less than 2.00, P is less than 0.035, S is less than 0.30, Ni = 9 ~ 13, Cr = 17.00 ~ 19.00, Nb is greater than 5 * C %
In air or chemical corrosion resistant to corrosion medium of a kind of high alloy steel, stainless steel is a beautiful surface and corrosion resistant performance is good, need not after surface treatment, such as color of plating and the surface of the stainless steel inherent performance, used in a variety of steel a, often called stainless steel. It represents the performance of 13 chrome steel, 18-8 chrome nickel steel.
From the perspective of metallography analysis, because the stainless steel containing chromium and make the surface form very thin chromium film, the film is isolated from intrusion in the steel corrosion of oxygen.
To maintain the corrosion resistance inherent in stainless steel, steel must contain more than 12 percent chromium.

TP347H STAINLESS STEEL PIPE COMPONENT:
tp347h Stainless steel pipe export is an important component of China’s export economy, it plays an important role in stimulating economic growth in our country, however, from the current our country foreign trade of stainless steel, stainless steel of our country 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, the 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.
For, external export difficulties, the stainless steel industry in China on the one hand to rights, but the most important still is the stainless steel industry in China to improve their quality level, and to conduct a comprehensive upgrade
