Super Austenitic Seamless Pipe PE 4" STD ASME B36.10M 904L Stainless Steel Round Pipe

Introduction

Stainless steel seamless steel pipe is a kind of long steel with hollow section and no joints around. Stainless steel seamless pipe

Features of stainless steel seamless pipe:

First, the thicker the wall thickness of the product is, the more economical and practical it is. The thinner the wall thickness is, the higher the processing cost will be; Secondly, the process of the product determines its limited performance. Generally, the precision of seamless steel pipe is low: uneven wall thickness, low brightness on the inner and outer surfaces of the pipe, high sizing cost, and pockmarks and black spots on the inner and outer surfaces are not easy to remove; Third, its detection and shaping must be handled offline. Therefore, it shows its advantages in high pressure, high strength and mechanical structure materials.

Duplex stainless steel has about half of ferrite phase and half of austenite phase in its solid solution structure. Generally, the content of small phase should reach 30%. With low C content, Cr content is 18%~28% and Ni content is 3%~10%. Some steels also contain alloy elements such as Mo, Cu, Nb, Ti and N.

904L (N08904, 14539) super austenitic stainless steel contains 14.0-18.0% chromium, 24.0-26.0% nickel and 4.5% molybdenum. 904L super austenitic stainless steel is a low-carbon, high nickel, molybdenum austenitic stainless acid resistant steel, which is a proprietary material imported from H · S Company of France. It has good activation passivation transformation ability, excellent corrosion resistance, good corrosion resistance in non oxidizing acids such as sulfuric acid, acetic acid, formic acid and phosphoric acid, good pitting resistance in neutral chloride containing medium, and good resistance to crevice corrosion and stress corrosion. It is applicable to various concentrations of sulfuric acid below 70 ℃. It can resist acetic acid of any concentration and temperature under normal pressure, and has good corrosion resistance in the mixed acid of formic acid and acetic acid.
