EN 1.4301 AISI 304 precision stainless steel tubing 8 X 1.0MM
EN10217-7 W2R AD2000 W2
Precision stainless steel tubing with excellent mechanical
properties, good corrosion resistance, more prominent cold
deformation capacity, non-magnetic, so widely used in aviation,
aerospace, ship and medical equipment and other fields. But the
precision stainless steel pipe cutting performance is much worse
than the carbon steel.
Typical Applications:
Moisture separator reheaters
Feedwater tubes
Heat exchangers
Typical Manufacturing Specifications:
ASTM A213
ASTM A249
ASTM A269
ASTM A270
EN10217-7
EN10296-2
EN10216-5
Also individual customer specifications.
Description:
Stainless steel types 1.4301 and 1.4307 are also known as grades
304 and 304L respectively. Type 304 is the most versatile and
widely used stainless steel. It is still sometimes referred to by
its old name 18/8 which is derived from the nominal composition of
type 304 being 18% chromium and 8% nickel.
Type 304 stainless steel is an austenitic grade that can be
severely deep drawn. This property has resulted in 304 being the
dominant grade used in applications like sinks and saucepans.
Type 304L is the low carbon version of 304. It is used in heavy
gauge components for improved weldability. Some products such as
plate and pipe may be available as “dual certified” material that
meets the criteria for both 304 and 304L.
304H, a high carbon content variant, is also available for use at
high temperatures.
