Description

DUPLEX 2304 STAINLESS STEEL PIPE BRIEF INTRODUCTION

DUPLEX 2304 STAINLESS STEEL PIPE / Duplex 2304 pipe is a low-alloy duplex stainless steel developed by Sweden.It has a solution temperature of about 1000 ℃, the organization has 40% -50% ferrite and 50% -60% austenite, with the common characteristics of duplex stainless steel, Is as a high strength and inexpensive features, can replace the 304L and 316L commonly used austenitic stainless steel and the development of steel.

It has been recognized by the American Society of Mechanical Engineers (ASME) for use in boilers and pressure vessels, chemical plants and refineries, and many countries have incorporated standards.

US standard for the UNS S32304, Sweden’s commercial grade SAF 2304 .

DUPLEX 2304 STAINLESS STEEL PIPE CORROSION RESISTANCE:

duplex 2304 duplex stainless steel pipe PRE value of 25, and 316L stainless steel value equivalent.The CPT value of duplex 2304 stainless steel pipewas higher than that of 304L, which was equivalent to that of 316L when the critical pitting temperature (CPT) and chloride ion content of several steels were tested in NaCl solution at 300mV.

The results of several steels in the neutral chloride solution of the autoclave found that the applied stress was equivalent to the yield strength of the steel at this temperature, and the test time was 1000 h, where the stress corrosion cracking did not occur under the curve.In addition SAF2304 duplex 2304 stainless steel pipe corrosion resistance between the good, can be CuSO4 + H2SO4 copper method test.

SAF2304 dual phase steel in nitric acid has a good corrosion resistance, can be comparable with 304L, in other acids, such as sulfuric acid, its corrosion resistance with 316L, and in organic acids, such as formic acid, and even better than 316L.
