Ferritic And Martensitic Welded Tube Of Stainless Steel

Stainless Steel: What, Where, Why of Ferritic Grades - Ryerson
In previous blogs we explored austenitic and martensitic stainless steels, detailing where to use some common grades and why. Here, the focus is on ferritic stainless steels. All stainless steels are iron-based alloys containing at least 10.5% chromium.
ASTM A268 for Seamless and Welded Ferritic and Martensitic
This guide covers standard specification for a number of grades of nominal-wall-thickness, welded ferritic and martensitic stainless steel tubing for general corrosion-resisting and high-temperature service.

Ferritic Stainless Steel Properties and Applications
Ferritic stainless steel alloys can generally be classified into five groups, three families of standard grades (Groups 1 to 3) and two families of specialty grade steels (Groups 4 and 5). While standard ferritic steels are, by far, the largest consumer group in terms of tonnage, demand for specialty grade stainless steels is increasing steadily.

Martensitic Stainless Steels | Stainless Steel Types
Martensitic Stainless Steel Grades. Martensitic stainless steels are characterized by high strength and hardness in the heat treated condition. We offer a range of martensitic stainless alloys which contain 11 – 17% chromium with 0.15 – 0.63% carbon.
Corrosion resistance levels in stainless steel - Ryerson
In fact, you can say that austenitic is the most popular family of all stainless steels, as about 50% of the stainless steel used today comes from this family—AISI 304 type, to be exact, which contains 18% chromium and 8% nickel. Look at your average food processing or dairy equipment and you will see an austenitic stainless steel-based product.
How to Weld Stainless Steel - The Definitive Guide for
Welding ferritic stainless steel. Ferritic stainless steel is often used in automotive industry, you can also find them in the AISI 400 series. Pure ferritic steel does not require pre-weld or post-weld heat treatments. If you add too much heat, ferritic stainless steel will drastically lose its strength because of grain growth.

Welded Stainless Steel Tubing Manufacturing Tour
Some alloy respond well to very short annealing times (ferritic and duplex alloys) and these can be effectively heat treated in-line on the tube mill while welding. Austenitic stainless steel and Ni alloys require significantly longer soak times and these alloys are heat treated in a continuous furnace .

Hydrogen Cracking of Ferritic-Austenitic Stainless Steel
The graph ( Fig.5) provides a guide to prevent fabrication hydrogen cracking in SMA welded ferritic-austenitic stainless steels. To illustrate the point, the work of Beeson [22] represents an in-service failure of SMA welded UNS S31803 duplex stainless steel. It was reported that cracks appeared to start at a highly ferritic (over 90% ferrite
Welded Tube - Penn Stainless
Beveling Stainless Steel tubes contain one end angled, so that it mates with a complementary tube end. Tubes can be beveled for certain applications in order to make welding of stainless steel tubes easier, which saves weld prep time and money compared to hand cutting.
