Al29-4C Applications

Al29-4C is a high performance austenitic stainless steel alloy that exhibits excellent resistance to pitting, crevice corrosion and general corrosion. The alloy is also highly resistant to chloride stress corrosion cracking. Al29-4C is used in a variety of applications that require superior corrosion resistance, such as chemical processing, petrochemical and power generation. The alloy is also commonly used in flue gas desulfurization (FGD) systems.

Al29-4C Double Wall:

Al29-4C double wall pipe is manufactured with an inner wall of Al29-4C stainless steel and an outer wall of 316L stainless steel. This pipe provides superior corrosion resistance to traditional single wall pipe while also providing increased strength and durability. Al29-4C double wall pipe is commonly used in aggressive environments where traditional single wall pipe would fail prematurely.


Duravent manufactures a full line of venting products for both residential and commercial applications. All Duravent products are designed to provide superior performance and durability. Duraventufffds product offerings include direct vent, B-vent, chimney relining systems, pellet venting systems and more.

ASTM A 959 Type 29-4c:

ASTM A 959 type 29-4c covers a heat resisting chromium nickel molybdenum columbium Alloy (UNS S31254) suitable for use in many high temperature applications such as heat exchangers, exhaust manifolds and turbine engine parts requiring creep resistance above 1000ufffdF (537ufffdC).
