ASTM A213 TP304L Stainless Steel Tubes For Superheater And
High-Temperature And High-Pressure Pipe Fittings
1. Description
The difference between 304, 304H and 304L
In fact, according to the content of chromium and nickel, all of them are 304 stainless steel, with 18% chromium (CR) and 8% nickel (Ni), but the main difference lies in the carbon content.
Among them, the highest carbon content is 304H, the lowest is 304L,
and the carbon content of 304 stainless steel is between the two.
The higher the carbon content, the worse the corrosion resistance
of stainless steel. Different carbon content also leads to
different prices. However, in actual use, different requirements
for different uses are different.
ASTM A213 TP304L is normally for Stainless steel boiler,
superheater and heat exchanger. Because it is a variety of alloy
components, it is very difficult to process hardness and cutting.
It is mainly used to manufacture high-temperature superheater,
high-temperature reheater, high-temperature section of platen
superheater and high-temperature and high-pressure pipe fittings of
large power generation boiler with large pressure parameters and
close to critical or supercritical.
ASTM A213 TP304L stainless steel seamless steel pipe can be
sprayed marks on the surface, threaded at both ends, chamfered at
both ends, and wear caps at both ends. Plywood
boxes packaging can make sure the safety during the
transportation. Our stainless steel seamless steel pipe are in good
quality and fully meet the different needs. The products are now
sold well in Asia, and have won the praise and satisfaction of
customers. They are widely used in many fields, especially in
heaters, and boilers.
