ASTM A269 TP304 Description
ASTM A269 is a standard developed by the American Society for
Testing and Materials (ASTM), which specifies the standard
specifications for seamless and welded stainless steel pipes for
general service,which covers grades of nominal-wall-thickness,
stainless steel tubing for general corrosion-resisting and low- or
high-temperature service.
Grade 304 is a 300 series stainless steel austenitic, which has a
minimum of 18% chromium and 8% nickel.Chromium is the basic element
to make stainless steel corrosion resistance. When the chromium
content in steel reaches about 12%, chromium reacts with oxygen in
the corrosive medium to form a thin oxide layer on the surface of
stainless steel, which can prevent further corrosion of the steel
matrix.
Stainless steel pipes are in different grades, categories and in
shapes.Stainless steel pipes are being manufactured in different
shapes,sizes, schedules and diameters as every application requires
different size and diameter. HNJBL stainless pipes are available in
different grades,as grade 201,304,304L,316,316L,etc.Stainless steel
tubing is easy to weld, cut, bend, and be processed into various
shapes and sizes according to specific needs to adapt to different
application scenarios.
