347H Round Special Steel Nickel Alloy Bar For Steel Structure Building

347H Stainless Steel Profiles round special steel nickel alloy bar for sale

1.Introduction

TP347H (1 cr19ni11nb) belong to the high carbon containing niobium Cr - Ni austenitic stainless steel,

due to containing stabilizing element Nb, its resistance to intercrystalline corrosion and sulfate

intergranular stress corrosion performance is good, the acid, alkali, salt and other corrosive medium

in the corrosion resistant and 18-8 containing Ti austenitic stainless steel, so it is widely used in boiler,

power generation, petroleum, chemical industry, synthetic fiber, food, paper and other industries.

Since Nb is less likely to burn out than Ti, this steel can also be used as a core for welding cr-ni

austenitic stainless steel.This steel has higher high temperature strength and better oxidation

resistance than 316 series, so it is often used as hot strength steel.

2.Chemical compositions

(1) high temperature strength and high temperature plasticity

(2) excellent oxidation resistance and corrosion resistance

(3) good organizational stability

(4) uniform chemical composition

(5) good machining performance and welding performance

(6) high dimensional accuracy and surface quality

4.application

347H austenitic stainless steel, with good corrosion resistance, welding performance and heat strength. 347H stainless steel is used for heat exchanger tubes for large boiler superheaters, reheaters, steam pipes and petrochemicals.
