TP347H stainless steel pipe

2017-12-05

Tp347h
stainless steel pipe is
a brand of stainless steel manufactured according to the ASTM
standard. tp347h stainless steel pipe s are equivalent to china
0Cr18Ni11Nb stainless steel pipe.

TP347H
STAINLESS STEEL PIPE BRIF INTRODUCTION.

tp347h
stainless steel pipe: chromium 18%, including nickel 11%

tp347h
stainless steel pipe = 0Cr18Ni11Nb contains Nb, which increases the
corrosion resistance of crystals and increases the strength and
plasticity. Reduce the thickness of the material. As a structural
strength component.

tp347h
stainless steel pipe heat treatment: solid solution treatment
(980-1150 ℃) cold fast

tp347h
mechanical properties of austenitic steel of stainless steel tube
with solid solution (GB/t4237-92)

Yield
strength is greater than 205 / MPa, the tensile strength is greater
than 520 / MPa, the elongation rate is greater than 35%, hardness
test: HBS is less than 187, HRB is less than 90, HV is less than 200

tp347h
stainless steel pipe chemical composition: C is less than 0.08, Si
less than 1.00, Mn is less than 2.00, P is less than 0.035, S is
less than 0.30, Ni = 9 ~ 13, Cr = 17.00 ~ 19.00, Nb is greater than
5 * C %

In
air or chemical corrosion resistant to corrosion medium of a kind of
high alloy steel, stainless steel is a beautiful surface and
corrosion resistant performance is good, need not after surface
treatment, such as color of plating and the surface of the stainless
steel inherent performance, used in a variety of steel a, often
called stainless steel. It represents the performance of 13 chrome
steel, 18-8 chrome nickel steel.

From
the perspective of metallography analysis, because the stainless
steel containing chromium and make the surface form very thin
chromium film, the film is isolated from intrusion in the steel
corrosion of oxygen.

To
maintain the corrosion resistance inherent in stainless steel, steel
must contain more than 12 percent chromium.

STAINLESS STEEL PIPE CHEMICAL COMPOSITIONS:

Stainless
steel 347 h

Name:
austenitic stainless steel

Standard:
AISI, ASTM

Model:
347 h.

UNS
number: S34709

347H
features and applications:

347H
austenitic stainless steel with good corrosion resistance, welding
performance and thermal performance. 347H stainless steel for the
heat exchanger pipe of large boiler superheater, reheater, steam
pipe and petrochemical.

The
chemical composition of 347H:

Carbon
C: 0.04 ~ 0.10

Mn
Mn: less than 2.00

Silicon
Si: less than 0.75

Cr:
17.0 ~ 19.0

Nickel

Niobium
Nb: (8C ~ 1.00)

Note:
the value of a single value is the highest unless otherwise
indicated. When used for certain pipe processes, some models of
austenitic stainless steel must be slightly higher than the number
shown in the table. (3) random; The maximum amount is 0.10%; The
maximum content is 0.75%; The maximum content is 0.70%

Yaang also supplies the same kind of products: 347H, tp347H stainless
steel pipe seamless
welded, tp347h stainless steel pipe fittings, tp347h stainless steel
pipe flanges

STAINLESS STEEL PIPE COMPONENT:

tp347h
Stainless steel pipe export is an important component of China’s
export economy, it plays an important role in stimulating economic
growth in our country, however, from the current our country
foreign trade of stainless steel, stainless steel of our country
export encountered greater resistance.

Since
last year, overseas frequently came to the stainless steel casting
products in China “double reverse” message, it has a great
influence for the stainless steel casting industry in China, and
exports are a good portion of the stainless steel industry
development in our country, in the development of the industry has
a huge market share, in the face of the economic downturn, the
development speed slow, the stainless steel industry development in
our country should continuously improve product quality, better the
development of overseas trade and against trade protectionism, the
products and environmental protection, energy resources, humanities
environment, enhance the competitiveness of the stainless steel
products, only in this way can the indefectible position in the
foreign trade.

For,
external export difficulties, the stainless steel industry in China
on the one hand to rights, but the most important still is the
stainless steel industry in China to improve their quality level,
and to conduct a comprehensive upgrade
