What is trip steel?

TRIP steel is Transformation Induced Plasticity steel. It is a composite steel that consists of ferrite, bainite, martensite precipitants and restrained austenite. The austenite will transform into martensite when strained, thus increasing the strength of the steel. To stabilize the… Full Answer

How many kinds of stainless steel are there?

Several. Ferritic, Austenite and Martensitic which can be further broken down into different types. . Austenite has the highest degree of corrosion resistance, ferritic has the best machinability while martensite is the most suitable for objects that need to be… Full Answer

What is full annealing?

Full annealing is the process of slowly raising the temperature about 50 ºC (90 ºF) above the Austenitic temperature line A3 or line ACM in the case of Hypoeutectoid steels (steels with < 0.77% Carbon) and 50 ºC (90 ºF)… Full Answer

What is intercritical annealing?

Intercritical annealing is where the metal is heated to between its lower and upper critical temperature point to allow partial transformation of the matrix into austenite followed by slow cooling or holding below the lower critical temperature point. Full Answer

How are flexon glasses made?

Flexon glasses are a titanium alloy like Nickel-Titanium. These are shape memory alloys that have the ability to transform between martensite and austenite phases when a load or temperature change is applied. they can be forged, extruded, or vacuum melted. Full Answer

How do you anneal a ferrous metal?

Annealing is the process of slowly raising the temperature about 50 ºC (90 ºF) above the Austenitic temperature. It is held at this temperature for sufficient time for all the material to transform into Austenite or Austenite-Cementite as the case… Full Answer

What is the purpose of Ferrite test?

The amount of ferrite present in austenitic or duplex stainless steels is called "FN" or Ferrite Number. For austenitic SS, a small amount of ferrite will decrease the tendency for hot cracking during solidification. Company specifications should have a required… Full Answer
