Can ultrasonic testing be used on stainless steel?

Ultrasonic testing of austenitic stainless steel welds False indications and the cause of their occurence – ScienceDirect.

Can you do UT on stainless steel?

An ultrasonic (UT) transducer developed under EPRI sponsorship is now widely used in nuclear plants for inspection of austenitic, stainless steel piping.

Is austenitic stainless steel Hardenable?

Austenitic steels, which contain 16 to 26 percent chromium and up to 35 percent nickel, usually have the highest corrosion resistance. They are not hardenable by heat treatment and are nonmagnetic.

What makes austenitic stainless steel prone to distortion?

Although classed as readily weldable, the austenitic stainless steels can be prone to distortion during and after welding. This is due mainly to their specific combination of physical properties, mainly their relatively high thermal expansion rate and low thermal conductivity.

What is meant by austenitic stainless steel?

Austenitic refers to an alloy consisting mainly of austenite. The most widely used grade of stainless steel is austenitic. Austenitic alloys contain a high percentage of nickel and chromium, which makes them, and the steel made from them, very resistant to corrosion.

Is 316 SS austenitic?

Type 316 stainless steel is an austenitic chromium-nickel stainless and heat-resisting steel with superior corrosion resistance as compared to other chromium-nickel steels when exposed to many types of chemical corrodents such as sea water, brine solutions, and the like.

Why is austenitic steel not magnetic?

In the case of steel, whether or not it is magnetic comes down to the microstructure of the steel. In austenitic steel, there is a higher percentage off chromium, and nickel is also present. In terms of magnetism, it is the addition of nickel that renders the steel non-magnetic.

What are the problems associated with welding of austenitic stainless steels?

Two problems are associated with welds in the austenitic stainless steels: 1) sensitization of the weld heat affected zone, and 2) hot cracking of weld metal. 3.3. 1 SENSITIZATION: Sensitization leads to intergranular corrosion in the heat affected zone as shown in Figure 1.

Is austenitic stainless steel weldable?

Austenitic stainless steel These alloys can be readily welded using any of the arc welding processes (TIG, MIG, MMA and SA). As they are non-hardenable on cooling, they exhibit good toughness and there is no need for pre- or post-weld heat treatment.

Why is it called austenitic stainless steel?

The term austenite is used to describe a face-centered cubic (FCC) iron or steel alloys that have this type of structure. It was named after Sir William Chandler Roberts-Austen, an Englishman known for his studies of the physical properties of metals.

What is austenitic steel used for?

Austenitic stainless steels are used for domestic, industrial, transport, and architectural products based primarily on their corrosion resistance but also for their formability, their strength, and their properties at extreme temperatures.

What is difference between SS 316 and SS 316L?

The key difference between 316 and 316L stainless steel is the carbon content. While 316 has a maximum carbon content of 0.08\%, 316L has a maximum carbon content of only 0.03\%.
