What is the quality of steel?

Steel quality is the summation of how well a steel meets its specified chemistry, the cleanliness of the steel or degree to which it is free of impurities or inclusion, homogeneity of the microstructure, grain/carbide size and in some instances if it meets the mechanical requirements for that particular steel.

What is steel and its classification?

Carbon Steel has three main subgroups depending on how much carbon is in the metal: Low Carbon Steels/Mild Steels (up to 0.3\% carbon), Medium Carbon Steels (0.3–0.6\% carbon), and High Carbon Steels (more than 0.6\% carbon).

What are the different ways of inspecting steel quality?

The most common methods are dye-penetrant, magnetic particle, radiographic, and ultrasonic inspection.

Where can I find the quality control manual?

The Quality Control Manual shall be the document for demonstrating compliance to the ASTM/ASME Code and/or customer specifications. Copies of the manual (uncontrolled) shall be distributed by the Quality Control Department. Copies will not be serialized. They are also available online at www.rangersteel.com.

What are the tests performed by quality control personnel?

Metallurgical, hardness, hardenability, tension, ductility, compression, fatigue, impact, wear, corrosion, creep, machinability, radiography, magnetic particle, ultrasonic, and eddy current are some of the major tests that are performed by quality control personnel.

What is the machinability rating of steel?

Machinability ratings are expressed as a percentage, in comparison with AISI 1112 steel, which is rated at 100\%. Metals which are more difficult to machine have a rating of less than 100\% while metals which machine easily have a rating more than 100\%. Radiography of metals involves the use of x rays or gamma rays.

What are the advantages of using alloyed steels?

Alloyed steels, in general, have an increased depth of hardenability which is one of the main advantages of using alloyed steels. Next to the hardness test, the tensile test is the most frequently performed test to determine certain mechanical properties.
