S34700 347H 07Cr18Ni11Tb ASTM A312 Cold Drawn / Cold Rolled Steel Pipe



Size Range:

1. Outer Diameter: 1/4" - 32" 
2. Wall thickness:1 mm-80mm 
3. Length: 6 metre or as per customer request 


1) Specifications:
347H is controlled, high carbon Nb stablised stainless steel for elevated temperature service.
General introduction: S347H is a austentic chromium steel containing colubium. It is recommended for parts fabricated by welding chich cannot be subsequently annealed. The addition of columbium produces a stablied type of stainless that eliminated carbide precipitation and consequently, intergranular corrosion.

Designed Features:
a. Superior general corrosion resistance over type 321 due to stabilization with columbium
b. Reduced tendencies to form contiunuous networks of chromium carbides at the grain boundaries.
c. Better high temperature properties than 304 or 304L. Generally used for parts which are intermittently heated up to 1500 deg. F. For continuous service the maximum temperature is 1650 deg. F.
d. Type 347H has high carbon (.04-.10) for better high temperature creep properties
e. Improved intergranular corrosion resistance.

Typical Application: High temperature chemical process, heat exchanger tubes, refineries, high temparature steam service.

(2) Process Method: Cold Drawn / Cold Rolled
