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.
