ASME SA249 TP304 Stainless Steel Bright Annealed Welded Tube Round
Tube
Yuhong Special Steel has been engaged in the operation of seamless welded pipes and
pipes of austenitic stainless steel and nickel alloy steel
(Hastelloy, Monel, Inconel, Inconel) for more than 25 years, with
an annual sales of more than 80,000 tons of steel pipes and pipes.
pipeline. Our customers have covered more than 45 countries
including the United States, Canada, Italy, the United Kingdom,
Germany, Chile, Colombia, Saudi Arabia, South Korea, Singapore,
Australia, Poland, and France.
Compared with traditionally used chromium-nickel steel, marine
grade SA 249 TP304 has excellent corrosion resistance, especially
during exposure to corrosive compounds. One of the reasons why the
stainless steel 316 Erw is considered superior to the
chromium-nickel steel grade is the addition of chromium to its
alloy. Although similar to austenitic alloy 304, 316 stainless
steel welded pipe is more resistant to sea water and salt
solutions. Therefore, welding 304 stainless steel pipe is
synonymous with marine engineering applications.
In addition, in addition to solutions containing sulfuric acid,
ASTM A249 TP304 tubes can also tolerate halides such as chloride,
bromide, and iodide. ASTM A249 TP304 welded boiler tubes are also
resistant to fatty acids in high temperature environments. In
addition, SA-249 TP304 will not lose its mechanical properties when
used in a wide temperature range. Because the alloy is non-toxic,
A249 TP304 welded pipe is usually used in industries with zero
tolerance for pollution. For example, the textile, pharmaceutical
and food and beverage industries prefer to use ASME SA 249 TP304
because it has no pollution characteristics.
ASTM A249 304 Welded Pipe can be tested to determine the grain size
of this particular alloy grade, in addition to a number of
mechanical tests such as flattening, flange, hardness, reverse
bending, tension and hydrostatic pressure or non-destructive
electrical. In addition to resistance to atmospheric corrosion, the
SA 249 Tp 304 equivalent material has good resistance to moderately
oxidizing and reducing environments. One of the benefits of using
welded 304 stainless steel pipe is that pipes produced from SA 249
Tp 304 are less expensive compared to other stainless steel alloys
and thus prove to be an economical choice for a variety of
applications. Trade name UNS S30400, Sa-249 Welded Pipe is one of
our most popular products.
